39180743 ÷ 931 
We're looking to find how many times 931 goes into 39180743.

Going ahead to step 1:
3 divided by 931 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 931

Let's proceed to step 2:
The number 931 fits into 39 0 times, leaving a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Include the next digit (1) from the dividend after 39, then repeat: 391 / 931

Going ahead to step 3:
The number 931 fits into 391 0 times, leaving a remainder of 391.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 391 and we're left with 391.
Append the next digit (8) from the dividend to 391 and continue with: 3918 / 931

Moving on to step 4:
If we divide 3918 by 931, we get 4 and a remainder of 194.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 3724 away from 3918, we end up with 194.
Grab the next digit (0) from the dividend, add it to 194, then carry on: 1940 / 931

Advancing to step 5:
When dividing 1940 by 931, we get 2 with a remainder of 78.
The next digit of our result is 2. 
Result so far: 42.0
If we subtract 1862 from 1940, we get 78.
Grab the next digit (7) from the dividend, add it to 78, then carry on: 787 / 931

On to step 6:
If we divide 787 by 931, we get 0 and a remainder of 787.
The number 0 becomes the next digit in our result. 
Result so far: 420.0
Subtract 0 from 787 to get 787.
Include the next digit (4) from the dividend after 787, then repeat: 7874 / 931

Advancing to step 7:
The number 931 fits into 7874 8 times, leaving a remainder of 426.
Put 8 as the next digit of the answer. 
Result so far: 4208.0
Subtract 7448 from 7874 to get 426.
Append the next digit (3) from the dividend to 426 and continue with: 4263 / 931

Moving on to step 8:
When dividing 4263 by 931, we get 4 with a remainder of 539.
The next digit of our result is 4. 
Result so far: 42084.0
Subtracting 3724 from 4263 leaves us with 539.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5390, and continue the process.

Step 9:
If we divide 5390 by 931, we get 5 and a remainder of 735.
Put 5 as the next digit of the answer. 
Result so far: 42084.5
If we subtract 4655 from 5390, we get 735.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7350, and continue the process.

Let's proceed to step 10:
931 can be fit into 7350 7 times, resulting in a remainder of 833.
Write down 7 as next digit of the result. 
Result so far: 42084.57
Subtract 6517 from 7350 to get 833.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8330, and continue the process.

On to step 11:
If we divide 8330 by 931, we get 8 and a remainder of 882.
The next digit of our result is 8. 
Result so far: 42084.578
If we take 7448 away from 8330, we end up with 882.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8820, and continue the process.

Going ahead to step 12:
8820 divided by 931 is 9 with a remainder of 441.
The number 9 becomes the next digit in our result. 
Result so far: 42084.5789
Deduct 8379 from 8820 and we're left with 441.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4410, and continue the process.

On to step 13:
If we divide 4410 by 931, we get 4 and a remainder of 686.
Use 4 as the next digit of our solution. 
Result so far: 42084.57894
If we take 3724 away from 4410, we end up with 686.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6860, and continue the process.

Step 14:
When dividing 6860 by 931, we get 7 with a remainder of 343.
Use 7 as the next digit of our solution. 
Result so far: 42084.578947
If we subtract 6517 from 6860, we get 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

Advancing to step 15:
3430 divided by 931 is 3 with a remainder of 637.
Record the quotient 3 as the next digit in the result. 
Result so far: 42084.5789473
Subtract 2793 from 3430 to get 637.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6370, and continue the process.

On to step 16:
6370 divided by 931 is 6 with a remainder of 784.
Record the quotient 6 as the next digit in the result. 
Result so far: 42084.57894736
Deduct 5586 from 6370 and we're left with 784.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7840, and continue the process.

The final outcome is 42084.57894736, with a leftover of 7.84e-07.
