Let's divide 521051 by 8
Let's see how many times 8 fits into 521051.

Moving on to step 1:
8 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 8

Going ahead to step 2:
When dividing 52 by 8, we get 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we subtract 48 from 52, we get 4.
Grab the next digit (1) from the dividend, add it to 4, then carry on: 41 / 8

Advancing to step 3:
When dividing 41 by 8, we get 5 with a remainder of 1.
The next digit of our result is 5. 
Result so far: 65.0
Subtract 40 from 41 to get 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 8

Advancing to step 4:
10 divided by 8 is 1 with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 651.0
If we subtract 8 from 10, we get 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 8

Moving on to step 5:
If we divide 25 by 8, we get 3 and a remainder of 1.
The next digit of our result is 3. 
Result so far: 6513.0
Subtract 24 from 25 to get 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 8

Let's proceed to step 6:
When dividing 11 by 8, we get 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 65131.0
Subtracting 8 from 11 leaves us 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 7:
30 divided by 8 is 3 with a remainder of 6.
The next digit of our result is 3. 
Result so far: 65131.3
If we take 24 away from 30, we end up 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 8:
8 can be fit into 60 7 times, resulting in a remainder of 4.
The next digit of our result is 7. 
Result so far: 65131.37
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.

Going ahead to step 9:
If we divide 40 by 8, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 65131.375
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:
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: 65131.375
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:
8 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 65131.375
Subtracting 0 from 0 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.

The quotient of the division is 65131.375, and the remainder is 0.0.
