84142 ÷ 8 
Our goal is to divide 84142 by 8.

On to step 1:
If we divide 8 by 8, we get 1 and a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 8 from 8 to get 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 8

Let's proceed to step 2:
The number 8 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 10.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (1) from the dividend, attach it to 4 and continue: 41 / 8

Step 3:
8 can be fit into 41 5 times, resulting in a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 105.0
The remainder is 1 after subtracting 40 from 41.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 8

Advancing to step 4:
When dividing 14 by 8, we get 1 with a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 1051.0
Subtracting 8 from 14 leaves us with 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 8

Let's proceed to step 5:
8 can be fit into 62 7 times, resulting in a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 10517.0
If we subtract 56 from 62, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 6:
The number 8 fits into 60 7 times, leaving a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 10517.7
If we subtract 56 from 60, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 7:
The number 8 fits into 40 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 10517.75
If we subtract 40 from 40, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
8 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 10517.75
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
When dividing 0 by 8, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10517.75
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 10517.75 with a remaining 0.0.
