Let's divide 42589691 by 8
We want to divide 42589691 by 8.

Advancing to step 1:
8 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 8

Moving on to step 2:
8 goes into 42 5 times with a remainder of 2.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtracting 40 from 42 leaves us with 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 8

Let's proceed to step 3:
When dividing 25 by 8, we get 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 53.0
Subtract 24 from 25 to get 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 8

Moving on to step 4:
8 goes into 18 2 times with a remainder of 2.
The next digit of our result is 2. 
Result so far: 532.0
If we subtract 16 from 18, we get 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 8

Step 5:
29 divided by 8 is 3 with a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 5323.0
Subtract 24 from 29 to get 5.
Append the next digit (6) from the dividend to 5 and continue with: 56 / 8

Step 6:
If we divide 56 by 8, we get 7 and a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 53237.0
Subtract 56 from 56 to get 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 8

Step 7:
When dividing 9 by 8, we get 1 with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 532371.0
The remainder is 1 after subtracting 8 from 9.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 8

Step 8:
When dividing 11 by 8, we get 1 with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 5323711.0
If we take 8 away from 11, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 9:
When dividing 30 by 8, we get 3 with a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 5323711.3
Subtracting 24 from 30 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 10:
If we divide 60 by 8, we get 7 and a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 5323711.37
Subtracting 56 from 60 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 11:
40 divided by 8 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 5323711.375
If we take 40 away from 40, 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.

Going ahead to step 12:
0 divided by 8 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 5323711.375
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.

Step 13:
When dividing 0 by 8, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 5323711.375
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.

After the division, we end up with 5323711.375 and a remainder of 0.0.
