Let's divide 74574217 by 391
We're looking to find how many times 391 goes into 74574217.

On to step 1:
The number 391 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 391

Let's proceed to step 2:
The number 391 fits into 74 0 times, leaving a remainder of 74.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 74, we end up with 74.
Grab the next digit (5) from the dividend, add it to 74, then carry on: 745 / 391

On to step 3:
If we divide 745 by 391, we get 1 and a remainder of 354.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 391 from 745 leaves us with 354.
Include the next digit (7) from the dividend after 354, then repeat: 3547 / 391

Advancing to step 4:
3547 divided by 391 is 9 with a remainder of 28.
Put 9 as the next digit of the answer. 
Result so far: 19.0
Deduct 3519 from 3547 and we're left with 28.
Include the next digit (4) from the dividend after 28, then repeat: 284 / 391

Going ahead to step 5:
When dividing 284 by 391, we get 0 with a remainder of 284.
Record the quotient 0 as the next digit in the result. 
Result so far: 190.0
If we subtract 0 from 284, we get 284.
Grab the next digit (2) from the dividend, add it to 284, then carry on: 2842 / 391

Going ahead to step 6:
If we divide 2842 by 391, we get 7 and a remainder of 105.
Record the quotient 7 as the next digit in the result. 
Result so far: 1907.0
If we subtract 2737 from 2842, we get 105.
Bring next digit (1) of the dividend behind the 105 and repeat the process: 1051 / 391

On to step 7:
If we divide 1051 by 391, we get 2 and a remainder of 269.
The next digit of our result is 2. 
Result so far: 19072.0
If we subtract 782 from 1051, we get 269.
Grab the next digit (7) from the dividend, add it to 269, then carry on: 2697 / 391

Step 8:
391 can be fit into 2697 6 times, resulting in a remainder of 351.
Put 6 as the next digit of the answer. 
Result so far: 190726.0
The remainder is 351 after subtracting 2346 from 2697.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

Let's proceed to step 9:
3510 divided by 391 is 8 with a remainder of 382.
The number 8 becomes the next digit in our result. 
Result so far: 190726.8
Subtract 3128 from 3510 to get 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Step 10:
3820 divided by 391 is 9 with a remainder of 301.
The number 9 becomes the next digit in our result. 
Result so far: 190726.89
Deduct 3519 from 3820 and we're left with 301.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

Step 11:
391 can be fit into 3010 7 times, resulting in a remainder of 273.
The next digit of our result is 7. 
Result so far: 190726.897
If we take 2737 away from 3010, we end up with 273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

Step 12:
2730 divided by 391 is 6 with a remainder of 384.
Put 6 as the next digit of the answer. 
Result so far: 190726.8976
Subtract 2346 from 2730 to get 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Advancing to step 13:
When dividing 3840 by 391, we get 9 with a remainder of 321.
Put 9 as the next digit of the answer. 
Result so far: 190726.89769
Deduct 3519 from 3840 and we're left with 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

Let's proceed to step 14:
391 can be fit into 3210 8 times, resulting in a remainder of 82.
The number 8 becomes the next digit in our result. 
Result so far: 190726.897698
If we subtract 3128 from 3210, we get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Going ahead to step 15:
391 goes into 820 2 times with a remainder of 38.
Write down 2 as next digit of the result. 
Result so far: 190726.8976982
The remainder is 38 after subtracting 782 from 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 16:
If we divide 380 by 391, we get 0 and a remainder of 380.
The next digit of our result is 0. 
Result so far: 190726.8976982
Deduct 0 from 380 and we're left with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

The final result is 190726.8976982 with a remainder of 3.8e-07.
