We look at the division of 31711925 by 397 
Let's see how many times 397 fits into 31711925.

Let's proceed to step 1:
397 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 397

Going ahead to step 2:
The number 397 fits into 31 0 times, leaving a remainder of 31.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 31 leaves us with 31.
Grab the next digit (7) from the dividend, add it to 31, then carry on: 317 / 397

On to step 3:
When dividing 317 by 397, we get 0 with a remainder of 317.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 317 to get 317.
Fetch the next digit (1) from the dividend, attach it to 317 and continue: 3171 / 397

Let's proceed to step 4:
If we divide 3171 by 397, we get 7 and a remainder of 392.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtract 2779 from 3171 to get 392.
Grab the next digit (1) from the dividend, add it to 392, then carry on: 3921 / 397

Advancing to step 5:
The number 397 fits into 3921 9 times, leaving a remainder of 348.
Write down 9 as next digit of the result. 
Result so far: 79.0
Subtracting 3573 from 3921 leaves us with 348.
Append the next digit (9) from the dividend to 348 and continue with: 3489 / 397

Advancing to step 6:
3489 divided by 397 is 8 with a remainder of 313.
Use 8 as the next digit of our solution. 
Result so far: 798.0
The remainder is 313 after subtracting 3176 from 3489.
Grab the next digit (2) from the dividend, add it to 313, then carry on: 3132 / 397

Let's proceed to step 7:
The number 397 fits into 3132 7 times, leaving a remainder of 353.
Use 7 as the next digit of our solution. 
Result so far: 7987.0
Deduct 2779 from 3132 and we're left with 353.
Grab the next digit (5) from the dividend, add it to 353, then carry on: 3535 / 397

Let's proceed to step 8:
3535 divided by 397 is 8 with a remainder of 359.
Use 8 as the next digit of our solution. 
Result so far: 79878.0
The remainder is 359 after subtracting 3176 from 3535.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3590, and continue the process.

Moving on to step 9:
The number 397 fits into 3590 9 times, leaving a remainder of 17.
Use 9 as the next digit of our solution. 
Result so far: 79878.9
Deduct 3573 from 3590 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 10:
170 divided by 397 is 0 with a remainder of 170.
Record the quotient 0 as the next digit in the result. 
Result so far: 79878.9
The remainder is 170 after subtracting 0 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Going ahead to step 11:
1700 divided by 397 is 4 with a remainder of 112.
Use 4 as the next digit of our solution. 
Result so far: 79878.904
If we take 1588 away from 1700, we end up with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Step 12:
When dividing 1120 by 397, we get 2 with a remainder of 326.
Put 2 as the next digit of the answer. 
Result so far: 79878.9042
Deduct 794 from 1120 and we're left with 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Let's proceed to step 13:
The number 397 fits into 3260 8 times, leaving a remainder of 84.
Write down 8 as next digit of the result. 
Result so far: 79878.90428
If we take 3176 away from 3260, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 14:
When dividing 840 by 397, we get 2 with a remainder of 46.
Write down 2 as next digit of the result. 
Result so far: 79878.904282
If we subtract 794 from 840, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 15:
When dividing 460 by 397, we get 1 with a remainder of 63.
Record the quotient 1 as the next digit in the result. 
Result so far: 79878.9042821
The remainder is 63 after subtracting 397 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Advancing to step 16:
630 divided by 397 is 1 with a remainder of 233.
The next digit of our result is 1. 
Result so far: 79878.90428211
If we subtract 397 from 630, we get 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

The final result is 79878.90428211 with a remainder of 2.33e-07.
