Let's divide 31203945 by 751
We want to figure out the number of times 31203945 can be divided by 751.

Going ahead to step 1:
751 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 751

Step 2:
751 can be fit into 31 0 times, resulting in a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Grab the next digit (2) from the dividend, add it to 31, then carry on: 312 / 751

Advancing to step 3:
751 goes into 312 0 times with a remainder of 312.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 312 to get 312.
Grab the next digit (0) from the dividend, add it to 312, then carry on: 3120 / 751

Step 4:
The number 751 fits into 3120 4 times, leaving a remainder of 116.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 116 after subtracting 3004 from 3120.
Grab the next digit (3) from the dividend, add it to 116, then carry on: 1163 / 751

Advancing to step 5:
1163 divided by 751 is 1 with a remainder of 412.
Write down 1 as next digit of the result. 
Result so far: 41.0
Subtracting 751 from 1163 leaves us with 412.
Grab the next digit (9) from the dividend, add it to 412, then carry on: 4129 / 751

Going ahead to step 6:
When dividing 4129 by 751, we get 5 with a remainder of 374.
The number 5 becomes the next digit in our result. 
Result so far: 415.0
The remainder is 374 after subtracting 3755 from 4129.
Append the next digit (4) from the dividend to 374 and continue with: 3744 / 751

Advancing to step 7:
3744 divided by 751 is 4 with a remainder of 740.
The next digit of our result is 4. 
Result so far: 4154.0
Subtracting 3004 from 3744 leaves us with 740.
Bring next digit (5) of the dividend behind the 740 and repeat the process: 7405 / 751

Let's proceed to step 8:
The number 751 fits into 7405 9 times, leaving a remainder of 646.
Record the quotient 9 as the next digit in the result. 
Result so far: 41549.0
The remainder is 646 after subtracting 6759 from 7405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6460, and continue the process.

Moving on to step 9:
When dividing 6460 by 751, we get 8 with a remainder of 452.
Write down 8 as next digit of the result. 
Result so far: 41549.8
Subtracting 6008 from 6460 leaves us with 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Step 10:
If we divide 4520 by 751, we get 6 and a remainder of 14.
The next digit of our result is 6. 
Result so far: 41549.86
Subtracting 4506 from 4520 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 11:
751 can be fit into 140 0 times, resulting in a remainder of 140.
Write down 0 as next digit of the result. 
Result so far: 41549.86
Deduct 0 from 140 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 12:
When dividing 1400 by 751, we get 1 with a remainder of 649.
Use 1 as the next digit of our solution. 
Result so far: 41549.8601
Subtract 751 from 1400 to get 649.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6490, and continue the process.

Advancing to step 13:
6490 divided by 751 is 8 with a remainder of 482.
Use 8 as the next digit of our solution. 
Result so far: 41549.86018
The remainder is 482 after subtracting 6008 from 6490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

Step 14:
751 can be fit into 4820 6 times, resulting in a remainder of 314.
The next digit of our result is 6. 
Result so far: 41549.860186
If we subtract 4506 from 4820, we get 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Step 15:
The number 751 fits into 3140 4 times, leaving a remainder of 136.
The next digit of our result is 4. 
Result so far: 41549.8601864
If we subtract 3004 from 3140, we get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Step 16:
751 can be fit into 1360 1 times, resulting in a remainder of 609.
Use 1 as the next digit of our solution. 
Result so far: 41549.86018641
If we take 751 away from 1360, we end up with 609.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6090, and continue the process.

The final outcome is 41549.86018641, with a leftover of 6.09e-07.
