Let's divide 42431522 by 988
Our goal is to divide 42431522 by 988.

Going ahead to step 1:
988 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
Subtract 0 from 4 to get 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 988

Let's proceed to step 2:
When dividing 42 by 988, we get 0 with a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Bring next digit (4) of the dividend behind the 42 and repeat the process: 424 / 988

Advancing to step 3:
The number 988 fits into 424 0 times, leaving a remainder of 424.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 424, we get 424.
Append the next digit (3) from the dividend to 424 and continue with: 4243 / 988

Let's proceed to step 4:
If we divide 4243 by 988, we get 4 and a remainder of 291.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 3952 from 4243 leaves us with 291.
Bring next digit (1) of the dividend behind the 291 and repeat the process: 2911 / 988

Step 5:
The number 988 fits into 2911 2 times, leaving a remainder of 935.
Record the quotient 2 as the next digit in the result. 
Result so far: 42.0
Subtracting 1976 from 2911 leaves us with 935.
Grab the next digit (5) from the dividend, add it to 935, then carry on: 9355 / 988

Moving on to step 6:
The number 988 fits into 9355 9 times, leaving a remainder of 463.
Record the quotient 9 as the next digit in the result. 
Result so far: 429.0
Deduct 8892 from 9355 and we're left with 463.
Grab the next digit (2) from the dividend, add it to 463, then carry on: 4632 / 988

Step 7:
988 goes into 4632 4 times with a remainder of 680.
Write down 4 as next digit of the result. 
Result so far: 4294.0
The remainder is 680 after subtracting 3952 from 4632.
Grab the next digit (2) from the dividend, add it to 680, then carry on: 6802 / 988

Going ahead to step 8:
When dividing 6802 by 988, we get 6 with a remainder of 874.
Use 6 as the next digit of our solution. 
Result so far: 42946.0
Subtract 5928 from 6802 to get 874.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8740, and continue the process.

Step 9:
The number 988 fits into 8740 8 times, leaving a remainder of 836.
The next digit of our result is 8. 
Result so far: 42946.8
If we take 7904 away from 8740, we end up with 836.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8360, and continue the process.

Step 10:
If we divide 8360 by 988, we get 8 and a remainder of 456.
Write down 8 as next digit of the result. 
Result so far: 42946.88
The remainder is 456 after subtracting 7904 from 8360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

The final outcome is 42946.88, with a leftover of 0.456.
