71015019 divided by 397 
We want to figure out the number of times 71015019 can be divided by 397.

On to step 1:
7 divided by 397 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 397

Advancing to step 2:
When dividing 71 by 397, we get 0 with a remainder of 71.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 71 to get 71.
Append the next digit (0) from the dividend to 71 and continue with: 710 / 397

Moving on to step 3:
The number 397 fits into 710 1 times, leaving a remainder of 313.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 397 from 710 leaves us with 313.
Append the next digit (1) from the dividend to 313 and continue with: 3131 / 397

Moving on to step 4:
397 goes into 3131 7 times with a remainder of 352.
Use 7 as the next digit of our solution. 
Result so far: 17.0
If we take 2779 away from 3131, we end up with 352.
Append the next digit (5) from the dividend to 352 and continue with: 3525 / 397

On to step 5:
If we divide 3525 by 397, we get 8 and a remainder of 349.
The next digit of our result is 8. 
Result so far: 178.0
If we take 3176 away from 3525, we end up with 349.
Fetch the next digit (0) from the dividend, attach it to 349 and continue: 3490 / 397

Going ahead to step 6:
The number 397 fits into 3490 8 times, leaving a remainder of 314.
Put 8 as the next digit of the answer. 
Result so far: 1788.0
If we subtract 3176 from 3490, we get 314.
Grab the next digit (1) from the dividend, add it to 314, then carry on: 3141 / 397

Moving on to step 7:
3141 divided by 397 is 7 with a remainder of 362.
Write down 7 as next digit of the result. 
Result so far: 17887.0
Subtract 2779 from 3141 to get 362.
Take the next digit (9) from the dividend and append it to 362, then repeat: 3629 / 397

Advancing to step 8:
When dividing 3629 by 397, we get 9 with a remainder of 56.
Write down 9 as next digit of the result. 
Result so far: 178879.0
Subtracting 3573 from 3629 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 9:
If we divide 560 by 397, we get 1 and a remainder of 163.
The number 1 becomes the next digit in our result. 
Result so far: 178879.1
If we take 397 away from 560, we end up with 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Step 10:
397 can be fit into 1630 4 times, resulting in a remainder of 42.
Write down 4 as next digit of the result. 
Result so far: 178879.14
Subtracting 1588 from 1630 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 11:
397 goes into 420 1 times with a remainder of 23.
The next digit of our result is 1. 
Result so far: 178879.141
Deduct 397 from 420 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 12:
397 goes into 230 0 times with a remainder of 230.
Put 0 as the next digit of the answer. 
Result so far: 178879.141
If we take 0 away from 230, we end up with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

On to step 13:
397 goes into 2300 5 times with a remainder of 315.
Put 5 as the next digit of the answer. 
Result so far: 178879.14105
If we subtract 1985 from 2300, we get 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

On to step 14:
The number 397 fits into 3150 7 times, leaving a remainder of 371.
The number 7 becomes the next digit in our result. 
Result so far: 178879.141057
If we take 2779 away from 3150, we end up with 371.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3710, and continue the process.

Going ahead to step 15:
3710 divided by 397 is 9 with a remainder of 137.
Use 9 as the next digit of our solution. 
Result so far: 178879.1410579
If we subtract 3573 from 3710, we get 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

On to step 16:
When dividing 1370 by 397, we get 3 with a remainder of 179.
Record the quotient 3 as the next digit in the result. 
Result so far: 178879.14105793
The remainder is 179 after subtracting 1191 from 1370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

The final outcome is 178879.14105793, with a leftover of 1.79e-07.
