Let's divide 74570662 by 399
Let's see how many times 399 fits into 74570662.

Step 1:
7 divided by 399 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 399

Going ahead 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
Subtracting 0 from 74 leaves us with 74.
Fetch the next digit (5) from the dividend, attach it to 74 and continue: 745 / 399

Moving on to step 3:
If we divide 745 by 399, we get 1 and a remainder of 346.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 399 from 745 and we're left with 346.
Fetch the next digit (7) from the dividend, attach it to 346 and continue: 3467 / 399

Advancing to step 4:
399 goes into 3467 8 times with a remainder of 275.
Use 8 as the next digit of our solution. 
Result so far: 18.0
If we take 3192 away from 3467, we end up with 275.
Take the next digit (0) from the dividend and append it to 275, then repeat: 2750 / 399

Going ahead to step 5:
2750 divided by 399 is 6 with a remainder of 356.
The next digit of our result is 6. 
Result so far: 186.0
If we take 2394 away from 2750, we end up with 356.
Append the next digit (6) from the dividend to 356 and continue with: 3566 / 399

Moving on to step 6:
399 goes into 3566 8 times with a remainder of 374.
Record the quotient 8 as the next digit in the result. 
Result so far: 1868.0
If we take 3192 away from 3566, we end up with 374.
Fetch the next digit (6) from the dividend, attach it to 374 and continue: 3746 / 399

Going ahead to step 7:
When dividing 3746 by 399, we get 9 with a remainder of 155.
Put 9 as the next digit of the answer. 
Result so far: 18689.0
Subtracting 3591 from 3746 leaves us with 155.
Append the next digit (2) from the dividend to 155 and continue with: 1552 / 399

Going ahead to step 8:
1552 divided by 399 is 3 with a remainder of 355.
Record the quotient 3 as the next digit in the result. 
Result so far: 186893.0
Subtracting 1197 from 1552 leaves us with 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

Going ahead to step 9:
When dividing 3550 by 399, we get 8 with a remainder of 358.
Record the quotient 8 as the next digit in the result. 
Result so far: 186893.8
The remainder is 358 after subtracting 3192 from 3550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Let's proceed to step 10:
If we divide 3580 by 399, we get 8 and a remainder of 388.
The number 8 becomes the next digit in our result. 
Result so far: 186893.88
If we subtract 3192 from 3580, we get 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

After the division, we end up with 186893.88 and a remainder of 0.388.
