We look at the division of 56403954 by 8 
We want to divide 56403954 by 8.

Advancing to step 1:
The number 8 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (6) from the dividend after 5, then repeat: 56 / 8

Moving on to step 2:
The number 8 fits into 56 7 times, leaving a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Deduct 56 from 56 and we're left with 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 8

Advancing to step 3:
When dividing 4 by 8, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 70.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 8

Advancing to step 4:
8 goes into 40 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 705.0
Deduct 40 from 40 and we're left with 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 8

Advancing to step 5:
3 divided by 8 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 7050.0
If we subtract 0 from 3, we get 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 8

Let's proceed to step 6:
39 divided by 8 is 4 with a remainder of 7.
Write down 4 as next digit of the result. 
Result so far: 70504.0
If we subtract 32 from 39, we get 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 8

Advancing to step 7:
8 can be fit into 75 9 times, resulting in a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 705049.0
If we subtract 72 from 75, we get 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 8

Let's proceed to step 8:
8 can be fit into 34 4 times, resulting in a remainder of 2.
The next digit of our result is 4. 
Result so far: 7050494.0
Subtracting 32 from 34 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 9:
The number 8 fits into 20 2 times, leaving a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 7050494.2
Deduct 16 from 20 and we're left 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.

Step 10:
40 divided by 8 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 7050494.25
Subtract 40 from 40 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.

Going ahead 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: 7050494.25
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.

Let's proceed to step 12:
0 divided by 8 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 7050494.25
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.

The quotient of the division is 7050494.25, and the remainder is 0.0.
