Let's divide 74904391 by 478
We want to figure out the number of times 74904391 can be divided by 478.

Moving on to step 1:
If we divide 7 by 478, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 478

Moving on to step 2:
When dividing 74 by 478, we get 0 with a remainder of 74.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 74 leaves us with 74.
Append the next digit (9) from the dividend to 74 and continue with: 749 / 478

Step 3:
If we divide 749 by 478, we get 1 and a remainder of 271.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 478 from 749 and we're left with 271.
Bring next digit (0) of the dividend behind the 271 and repeat the process: 2710 / 478

Advancing to step 4:
The number 478 fits into 2710 5 times, leaving a remainder of 320.
Put 5 as the next digit of the answer. 
Result so far: 15.0
The remainder is 320 after subtracting 2390 from 2710.
Include the next digit (4) from the dividend after 320, then repeat: 3204 / 478

Let's proceed to step 5:
If we divide 3204 by 478, we get 6 and a remainder of 336.
The next digit of our result is 6. 
Result so far: 156.0
Subtracting 2868 from 3204 leaves us with 336.
Fetch the next digit (3) from the dividend, attach it to 336 and continue: 3363 / 478

Advancing to step 6:
When dividing 3363 by 478, we get 7 with a remainder of 17.
The next digit of our result is 7. 
Result so far: 1567.0
If we subtract 3346 from 3363, we get 17.
Grab the next digit (9) from the dividend, add it to 17, then carry on: 179 / 478

Moving on to step 7:
478 can be fit into 179 0 times, resulting in a remainder of 179.
Use 0 as the next digit of our solution. 
Result so far: 15670.0
The remainder is 179 after subtracting 0 from 179.
Grab the next digit (1) from the dividend, add it to 179, then carry on: 1791 / 478

Advancing to step 8:
The number 478 fits into 1791 3 times, leaving a remainder of 357.
The next digit of our result is 3. 
Result so far: 156703.0
Deduct 1434 from 1791 and we're left with 357.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3570, and continue the process.

Advancing to step 9:
478 can be fit into 3570 7 times, resulting in a remainder of 224.
The next digit of our result is 7. 
Result so far: 156703.7
Deduct 3346 from 3570 and we're left with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Advancing to step 10:
If we divide 2240 by 478, we get 4 and a remainder of 328.
Record the quotient 4 as the next digit in the result. 
Result so far: 156703.74
Subtracting 1912 from 2240 leaves us with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Advancing to step 11:
478 goes into 3280 6 times with a remainder of 412.
Record the quotient 6 as the next digit in the result. 
Result so far: 156703.746
Deduct 2868 from 3280 and we're left with 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Moving on to step 12:
4120 divided by 478 is 8 with a remainder of 296.
The next digit of our result is 8. 
Result so far: 156703.7468
Subtract 3824 from 4120 to get 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Moving on to step 13:
If we divide 2960 by 478, we get 6 and a remainder of 92.
The next digit of our result is 6. 
Result so far: 156703.74686
The remainder is 92 after subtracting 2868 from 2960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Step 14:
When dividing 920 by 478, we get 1 with a remainder of 442.
The next digit of our result is 1. 
Result so far: 156703.746861
If we take 478 away from 920, we end up with 442.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

On to step 15:
The number 478 fits into 4420 9 times, leaving a remainder of 118.
Use 9 as the next digit of our solution. 
Result so far: 156703.7468619
If we take 4302 away from 4420, we end up with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

On to step 16:
1180 divided by 478 is 2 with a remainder of 224.
Record the quotient 2 as the next digit in the result. 
Result so far: 156703.74686192
Deduct 956 from 1180 and we're left with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

The final result is 156703.74686192 with a remainder of 2.24e-07.
