We look at the division of 40146930 by 938 
We want to figure out the number of times 40146930 can be divided by 938.

Going ahead to step 1:
4 divided by 938 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 938

Moving on to step 2:
938 can be fit into 40 0 times, resulting in a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Grab the next digit (1) from the dividend, add it to 40, then carry on: 401 / 938

Advancing to step 3:
When dividing 401 by 938, we get 0 with a remainder of 401.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 401, we end up with 401.
Take the next digit (4) from the dividend and append it to 401, then repeat: 4014 / 938

On to step 4:
The number 938 fits into 4014 4 times, leaving a remainder of 262.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 262 after subtracting 3752 from 4014.
Include the next digit (6) from the dividend after 262, then repeat: 2626 / 938

Moving on to step 5:
If we divide 2626 by 938, we get 2 and a remainder of 750.
Write down 2 as next digit of the result. 
Result so far: 42.0
Subtracting 1876 from 2626 leaves us with 750.
Grab the next digit (9) from the dividend, add it to 750, then carry on: 7509 / 938

Step 6:
The number 938 fits into 7509 8 times, leaving a remainder of 5.
Use 8 as the next digit of our solution. 
Result so far: 428.0
If we take 7504 away from 7509, we end up with 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 938

Moving on to step 7:
53 divided by 938 is 0 with a remainder of 53.
Use 0 as the next digit of our solution. 
Result so far: 4280.0
If we take 0 away from 53, we end up with 53.
Fetch the next digit (0) from the dividend, attach it to 53 and continue: 530 / 938

Step 8:
938 goes into 530 0 times with a remainder of 530.
Record the quotient 0 as the next digit in the result. 
Result so far: 42800.0
The remainder is 530 after subtracting 0 from 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Step 9:
938 goes into 5300 5 times with a remainder of 610.
Record the quotient 5 as the next digit in the result. 
Result so far: 42800.5
Subtracting 4690 from 5300 leaves us with 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Step 10:
6100 divided by 938 is 6 with a remainder of 472.
Record the quotient 6 as the next digit in the result. 
Result so far: 42800.56
If we take 5628 away from 6100, we end up with 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Step 11:
4720 divided by 938 is 5 with a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 42800.565
If we subtract 4690 from 4720, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 12:
938 can be fit into 300 0 times, resulting in a remainder of 300.
Use 0 as the next digit of our solution. 
Result so far: 42800.565
Subtract 0 from 300 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

On to step 13:
The number 938 fits into 3000 3 times, leaving a remainder of 186.
Write down 3 as next digit of the result. 
Result so far: 42800.56503
Deduct 2814 from 3000 and we're left with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Step 14:
938 goes into 1860 1 times with a remainder of 922.
The number 1 becomes the next digit in our result. 
Result so far: 42800.565031
If we subtract 938 from 1860, we get 922.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9220, and continue the process.

On to step 15:
If we divide 9220 by 938, we get 9 and a remainder of 778.
Record the quotient 9 as the next digit in the result. 
Result so far: 42800.5650319
Deduct 8442 from 9220 and we're left with 778.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7780, and continue the process.

Going ahead to step 16:
938 goes into 7780 8 times with a remainder of 276.
Write down 8 as next digit of the result. 
Result so far: 42800.56503198
If we take 7504 away from 7780, we end up with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

After the division, we end up with 42800.56503198 and a remainder of 2.76e-07.
