We divide 840912 by 8
The aim is to understand the frequency of 8 in 840912.

Moving on to step 1:
8 can be fit into 8 1 times, resulting in a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 8 from 8 leaves us with 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 8

On to step 2:
If we divide 4 by 8, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 10.0
Subtract 0 from 4 to get 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 8

Moving on to step 3:
40 divided by 8 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 105.0
Subtracting 40 from 40 leaves us with 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 8

On to step 4:
When dividing 9 by 8, we get 1 with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 1051.0
The remainder is 1 after subtracting 8 from 9.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 8

Going ahead to step 5:
The number 8 fits into 11 1 times, leaving a remainder of 3.
The next digit of our result is 1. 
Result so far: 10511.0
Subtract 8 from 11 to get 3.
Take the next digit (2) from the dividend and append it to 3, then repeat: 32 / 8

Advancing to step 6:
8 can be fit into 32 4 times, resulting in a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 105114.0
If we take 32 away from 32, 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.

Step 7:
The number 8 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 105114.0
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.

Advancing to step 8:
0 divided by 8 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 105114.0
If we subtract 0 from 0, we 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.

The quotient of the division is 105114.0, and the remainder is 0.0.
