74372158 ÷ 399 
We want to figure out the number of times 74372158 can be divided by 399.

Moving on to step 1:
399 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 399

On to step 2:
When dividing 74 by 399, we get 0 with a remainder of 74.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 74 and we're left with 74.
Append the next digit (3) from the dividend to 74 and continue with: 743 / 399

On to step 3:
When dividing 743 by 399, we get 1 with a remainder of 344.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 399 from 743, we get 344.
Append the next digit (7) from the dividend to 344 and continue with: 3447 / 399

Let's proceed to step 4:
The number 399 fits into 3447 8 times, leaving a remainder of 255.
The next digit of our result is 8. 
Result so far: 18.0
The remainder is 255 after subtracting 3192 from 3447.
Take the next digit (2) from the dividend and append it to 255, then repeat: 2552 / 399

On to step 5:
2552 divided by 399 is 6 with a remainder of 158.
The next digit of our result is 6. 
Result so far: 186.0
Subtract 2394 from 2552 to get 158.
Fetch the next digit (1) from the dividend, attach it to 158 and continue: 1581 / 399

Advancing to step 6:
399 goes into 1581 3 times with a remainder of 384.
Write down 3 as next digit of the result. 
Result so far: 1863.0
Subtract 1197 from 1581 to get 384.
Fetch the next digit (5) from the dividend, attach it to 384 and continue: 3845 / 399

Advancing to step 7:
If we divide 3845 by 399, we get 9 and a remainder of 254.
Record the quotient 9 as the next digit in the result. 
Result so far: 18639.0
If we take 3591 away from 3845, we end up with 254.
Include the next digit (8) from the dividend after 254, then repeat: 2548 / 399

Going ahead to step 8:
The number 399 fits into 2548 6 times, leaving a remainder of 154.
Record the quotient 6 as the next digit in the result. 
Result so far: 186396.0
Subtracting 2394 from 2548 leaves us with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Moving on to step 9:
399 goes into 1540 3 times with a remainder of 343.
Write down 3 as next digit of the result. 
Result so far: 186396.3
Deduct 1197 from 1540 and we're left with 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

Step 10:
3430 divided by 399 is 8 with a remainder of 238.
Write down 8 as next digit of the result. 
Result so far: 186396.38
Subtract 3192 from 3430 to get 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Moving on to step 11:
The number 399 fits into 2380 5 times, leaving a remainder of 385.
The next digit of our result is 5. 
Result so far: 186396.385
If we take 1995 away from 2380, we end up with 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Going ahead to step 12:
3850 divided by 399 is 9 with a remainder of 259.
Record the quotient 9 as the next digit in the result. 
Result so far: 186396.3859
Deduct 3591 from 3850 and we're left with 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

Let's proceed to step 13:
2590 divided by 399 is 6 with a remainder of 196.
The number 6 becomes the next digit in our result. 
Result so far: 186396.38596
Subtract 2394 from 2590 to get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Step 14:
When dividing 1960 by 399, we get 4 with a remainder of 364.
Put 4 as the next digit of the answer. 
Result so far: 186396.385964
If we subtract 1596 from 1960, we get 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

On to step 15:
3640 divided by 399 is 9 with a remainder of 49.
The next digit of our result is 9. 
Result so far: 186396.3859649
If we subtract 3591 from 3640, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 16:
If we divide 490 by 399, we get 1 and a remainder of 91.
The number 1 becomes the next digit in our result. 
Result so far: 186396.38596491
Subtract 399 from 490 to get 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

In conclusion, the division gives 186396.38596491 with a balance of 9.1e-08.
