We're dividing 42628528 by 398 
We want to divide 42628528 by 398.

Going ahead to step 1:
398 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 398

Step 2:
398 goes into 42 0 times with a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Append the next digit (6) from the dividend to 42 and continue with: 426 / 398

Advancing to step 3:
If we divide 426 by 398, we get 1 and a remainder of 28.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 398 from 426 and we're left with 28.
Append the next digit (2) from the dividend to 28 and continue with: 282 / 398

Advancing to step 4:
The number 398 fits into 282 0 times, leaving a remainder of 282.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtract 0 from 282 to get 282.
Take the next digit (8) from the dividend and append it to 282, then repeat: 2828 / 398

On to step 5:
2828 divided by 398 is 7 with a remainder of 42.
The next digit of our result is 7. 
Result so far: 107.0
The remainder is 42 after subtracting 2786 from 2828.
Bring next digit (5) of the dividend behind the 42 and repeat the process: 425 / 398

Going ahead to step 6:
398 can be fit into 425 1 times, resulting in a remainder of 27.
The next digit of our result is 1. 
Result so far: 1071.0
If we take 398 away from 425, we end up with 27.
Append the next digit (2) from the dividend to 27 and continue with: 272 / 398

Let's proceed to step 7:
When dividing 272 by 398, we get 0 with a remainder of 272.
The number 0 becomes the next digit in our result. 
Result so far: 10710.0
Subtracting 0 from 272 leaves us with 272.
Include the next digit (8) from the dividend after 272, then repeat: 2728 / 398

On to step 8:
398 goes into 2728 6 times with a remainder of 340.
Use 6 as the next digit of our solution. 
Result so far: 107106.0
Deduct 2388 from 2728 and we're left with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Let's proceed to step 9:
The number 398 fits into 3400 8 times, leaving a remainder of 216.
The next digit of our result is 8. 
Result so far: 107106.8
If we take 3184 away from 3400, we end up with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Step 10:
If we divide 2160 by 398, we get 5 and a remainder of 170.
The number 5 becomes the next digit in our result. 
Result so far: 107106.85
Deduct 1990 from 2160 and we're left with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Moving on to step 11:
1700 divided by 398 is 4 with a remainder of 108.
Record the quotient 4 as the next digit in the result. 
Result so far: 107106.854
The remainder is 108 after subtracting 1592 from 1700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Moving on to step 12:
398 can be fit into 1080 2 times, resulting in a remainder of 284.
The number 2 becomes the next digit in our result. 
Result so far: 107106.8542
If we take 796 away from 1080, we end up with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

On to step 13:
The number 398 fits into 2840 7 times, leaving a remainder of 54.
Record the quotient 7 as the next digit in the result. 
Result so far: 107106.85427
If we subtract 2786 from 2840, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 14:
540 divided by 398 is 1 with a remainder of 142.
The number 1 becomes the next digit in our result. 
Result so far: 107106.854271
The remainder is 142 after subtracting 398 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Advancing to step 15:
If we divide 1420 by 398, we get 3 and a remainder of 226.
Put 3 as the next digit of the answer. 
Result so far: 107106.8542713
If we subtract 1194 from 1420, we get 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Going ahead to step 16:
398 can be fit into 2260 5 times, resulting in a remainder of 270.
Write down 5 as next digit of the result. 
Result so far: 107106.85427135
Subtract 1990 from 2260 to get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

The final outcome is 107106.85427135, with a leftover of 2.7e-07.
