We're dividing 71317531 by 397 
Our goal is to divide 71317531 by 397.

On to step 1:
The number 397 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 397

Step 2:
If we divide 71 by 397, we get 0 and a remainder of 71.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 71, we end up with 71.
Grab the next digit (3) from the dividend, add it to 71, then carry on: 713 / 397

Step 3:
If we divide 713 by 397, we get 1 and a remainder of 316.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 397 away from 713, we end up with 316.
Append the next digit (1) from the dividend to 316 and continue with: 3161 / 397

Going ahead to step 4:
3161 divided by 397 is 7 with a remainder of 382.
Write down 7 as next digit of the result. 
Result so far: 17.0
If we subtract 2779 from 3161, we get 382.
Take the next digit (7) from the dividend and append it to 382, then repeat: 3827 / 397

Going ahead to step 5:
If we divide 3827 by 397, we get 9 and a remainder of 254.
Record the quotient 9 as the next digit in the result. 
Result so far: 179.0
The remainder is 254 after subtracting 3573 from 3827.
Append the next digit (5) from the dividend to 254 and continue with: 2545 / 397

Advancing to step 6:
The number 397 fits into 2545 6 times, leaving a remainder of 163.
The number 6 becomes the next digit in our result. 
Result so far: 1796.0
The remainder is 163 after subtracting 2382 from 2545.
Take the next digit (3) from the dividend and append it to 163, then repeat: 1633 / 397

Step 7:
If we divide 1633 by 397, we get 4 and a remainder of 45.
The number 4 becomes the next digit in our result. 
Result so far: 17964.0
Subtracting 1588 from 1633 leaves us with 45.
Append the next digit (1) from the dividend to 45 and continue with: 451 / 397

Going ahead to step 8:
The number 397 fits into 451 1 times, leaving a remainder of 54.
Record the quotient 1 as the next digit in the result. 
Result so far: 179641.0
If we subtract 397 from 451, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 9:
397 goes into 540 1 times with a remainder of 143.
Record the quotient 1 as the next digit in the result. 
Result so far: 179641.1
Subtracting 397 from 540 leaves us with 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Going ahead to step 10:
The number 397 fits into 1430 3 times, leaving a remainder of 239.
Record the quotient 3 as the next digit in the result. 
Result so far: 179641.13
The remainder is 239 after subtracting 1191 from 1430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

Going ahead to step 11:
The number 397 fits into 2390 6 times, leaving a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 179641.136
The remainder is 8 after subtracting 2382 from 2390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 12:
The number 397 fits into 80 0 times, leaving a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 179641.136
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 13:
If we divide 800 by 397, we get 2 and a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 179641.13602
The remainder is 6 after subtracting 794 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 14:
If we divide 60 by 397, we get 0 and a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 179641.13602
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 15:
397 can be fit into 600 1 times, resulting in a remainder of 203.
Put 1 as the next digit of the answer. 
Result so far: 179641.1360201
Subtracting 397 from 600 leaves us with 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Step 16:
The number 397 fits into 2030 5 times, leaving a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 179641.13602015
The remainder is 45 after subtracting 1985 from 2030.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

The final result is 179641.13602015 with a remainder of 4.5e-08.
