Let's divide 74978136 by 391
Our goal is to divide 74978136 by 391.

Step 1:
391 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 391

Let's proceed to step 2:
When dividing 74 by 391, we get 0 with a remainder of 74.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 74 to get 74.
Fetch the next digit (9) from the dividend, attach it to 74 and continue: 749 / 391

Advancing to step 3:
391 goes into 749 1 times with a remainder of 358.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 391 from 749 leaves us with 358.
Fetch the next digit (7) from the dividend, attach it to 358 and continue: 3587 / 391

Moving on to step 4:
When dividing 3587 by 391, we get 9 with a remainder of 68.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
Deduct 3519 from 3587 and we're left with 68.
Include the next digit (8) from the dividend after 68, then repeat: 688 / 391

Going ahead to step 5:
When dividing 688 by 391, we get 1 with a remainder of 297.
Use 1 as the next digit of our solution. 
Result so far: 191.0
Subtract 391 from 688 to get 297.
Fetch the next digit (1) from the dividend, attach it to 297 and continue: 2971 / 391

Going ahead to step 6:
When dividing 2971 by 391, we get 7 with a remainder of 234.
Record the quotient 7 as the next digit in the result. 
Result so far: 1917.0
Subtract 2737 from 2971 to get 234.
Fetch the next digit (3) from the dividend, attach it to 234 and continue: 2343 / 391

Going ahead to step 7:
391 can be fit into 2343 5 times, resulting in a remainder of 388.
Write down 5 as next digit of the result. 
Result so far: 19175.0
If we take 1955 away from 2343, we end up with 388.
Append the next digit (6) from the dividend to 388 and continue with: 3886 / 391

Going ahead to step 8:
3886 divided by 391 is 9 with a remainder of 367.
Use 9 as the next digit of our solution. 
Result so far: 191759.0
If we subtract 3519 from 3886, we get 367.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3670, and continue the process.

Advancing to step 9:
3670 divided by 391 is 9 with a remainder of 151.
The next digit of our result is 9. 
Result so far: 191759.9
Deduct 3519 from 3670 and we're left with 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Let's proceed to step 10:
391 goes into 1510 3 times with a remainder of 337.
Use 3 as the next digit of our solution. 
Result so far: 191759.93
If we subtract 1173 from 1510, we get 337.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3370, and continue the process.

Going ahead to step 11:
3370 divided by 391 is 8 with a remainder of 242.
The next digit of our result is 8. 
Result so far: 191759.938
Deduct 3128 from 3370 and we're left with 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Going ahead to step 12:
If we divide 2420 by 391, we get 6 and a remainder of 74.
Write down 6 as next digit of the result. 
Result so far: 191759.9386
Deduct 2346 from 2420 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 13:
740 divided by 391 is 1 with a remainder of 349.
Put 1 as the next digit of the answer. 
Result so far: 191759.93861
Deduct 391 from 740 and we're left with 349.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3490, and continue the process.

Advancing to step 14:
3490 divided by 391 is 8 with a remainder of 362.
The number 8 becomes the next digit in our result. 
Result so far: 191759.938618
Subtracting 3128 from 3490 leaves us with 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Moving on to step 15:
The number 391 fits into 3620 9 times, leaving a remainder of 101.
The number 9 becomes the next digit in our result. 
Result so far: 191759.9386189
The remainder is 101 after subtracting 3519 from 3620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Moving on to step 16:
391 can be fit into 1010 2 times, resulting in a remainder of 228.
Write down 2 as next digit of the result. 
Result so far: 191759.93861892
If we subtract 782 from 1010, we get 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

After the division, we end up with 191759.93861892 and a remainder of 2.28e-07.
