We look at the division of 120825 by 8 
We want to figure out the number of times 120825 can be divided by 8.

Step 1:
8 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 8

Moving on to step 2:
When dividing 12 by 8, we get 1 with a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 8 from 12, we get 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 8

Step 3:
When dividing 40 by 8, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
If we subtract 40 from 40, we get 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 8

Advancing to step 4:
If we divide 8 by 8, we get 1 and a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 151.0
Subtracting 8 from 8 leaves us with 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 8

Step 5:
2 divided by 8 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 1510.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 8

Moving on to step 6:
25 divided by 8 is 3 with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 15103.0
Subtracting 24 from 25 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
The number 8 fits into 10 1 times, leaving a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 15103.1
If we subtract 8 from 10, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
The number 8 fits into 20 2 times, leaving a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 15103.12
Subtracting 16 from 20 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.

On to step 9:
8 goes into 40 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 15103.125
Deduct 40 from 40 and we're left 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.

On to step 10:
If we divide 0 by 8, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 15103.125
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 11:
The number 8 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 15103.125
Deduct 0 from 0 and we're left 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.

After the division, we end up with 15103.125 and a remainder of 0.0.
