Let's divide 13404657 by 8
Our goal is to divide 13404657 by 8.

Going ahead to step 1:
The number 8 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 8

Let's proceed to step 2:
13 divided by 8 is 1 with a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 8 away from 13, we end up with 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 8

Step 3:
54 divided by 8 is 6 with a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Subtract 48 from 54 to get 6.
Take the next digit (0) from the dividend and append it to 6, then repeat: 60 / 8

Let's proceed to step 4:
8 can be fit into 60 7 times, resulting in a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 167.0
If we subtract 56 from 60, we get 4.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 8

Step 5:
The number 8 fits into 44 5 times, leaving a remainder of 4.
The next digit of our result is 5. 
Result so far: 1675.0
Subtract 40 from 44 to get 4.
Take the next digit (6) from the dividend and append it to 4, then repeat: 46 / 8

Step 6:
8 can be fit into 46 5 times, resulting in a remainder of 6.
Write down 5 as next digit of the result. 
Result so far: 16755.0
Subtract 40 from 46 to get 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 8

Moving on to step 7:
8 goes into 65 8 times with a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 167558.0
If we take 64 away from 65, we end up with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 8

Let's proceed to step 8:
When dividing 17 by 8, we get 2 with a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 1675582.0
If we take 16 away from 17, we end up 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.

On to step 9:
8 goes into 10 1 times with a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 1675582.1
Subtracting 8 from 10 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.

On to step 10:
When dividing 20 by 8, we get 2 with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 1675582.12
If we subtract 16 from 20, 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 11:
The number 8 fits into 40 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 1675582.125
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.

Let's proceed to step 12:
0 divided by 8 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 1675582.125
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.

On to step 13:
0 divided by 8 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 1675582.125
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.

The final outcome is 1675582.125, with a leftover of 0.0.
