We're dividing 84429428 by 8 
Our goal is to divide 84429428 by 8.

Going ahead to step 1:
8 goes into 8 1 times with a remainder of 0.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 0 after subtracting 8 from 8.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 8

Step 2:
The number 8 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we take 0 away from 4, we end up with 4.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 8

Let's proceed to step 3:
8 goes into 44 5 times with a remainder of 4.
Put 5 as the next digit of the answer. 
Result so far: 105.0
If we subtract 40 from 44, we get 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 8

Advancing to step 4:
The number 8 fits into 42 5 times, leaving a remainder of 2.
Write down 5 as next digit of the result. 
Result so far: 1055.0
If we take 40 away from 42, we end up with 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 8

Moving on to step 5:
8 goes into 29 3 times with a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 10553.0
Subtracting 24 from 29 leaves us with 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 8

Going ahead to step 6:
When dividing 54 by 8, we get 6 with a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 105536.0
Subtracting 48 from 54 leaves us with 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 8

Going ahead to step 7:
62 divided by 8 is 7 with a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 1055367.0
Subtracting 56 from 62 leaves us with 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 8

Let's proceed to step 8:
If we divide 68 by 8, we get 8 and a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 10553678.0
Subtract 64 from 68 to 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 9:
8 goes into 40 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 10553678.5
Subtracting 40 from 40 leaves us with 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 10:
8 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 10553678.5
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 11:
If we divide 0 by 8, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 10553678.5
Subtract 0 from 0 to 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.

The final outcome is 10553678.5, with a leftover of 0.0.
