837432 divided by 8 
The aim is to understand the frequency of 8 in 837432.

On to step 1:
8 divided by 8 is 1 with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 8 away from 8, we end up with 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 8

Moving on to step 2:
3 divided by 8 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 8

On to step 3:
8 goes into 37 4 times with a remainder of 5.
Write down 4 as next digit of the result. 
Result so far: 104.0
Subtract 32 from 37 to get 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 8

On to step 4:
8 goes into 54 6 times with a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 1046.0
If we take 48 away from 54, we end up with 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 8

Step 5:
63 divided by 8 is 7 with a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 10467.0
Subtracting 56 from 63 leaves us with 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 8

Advancing to step 6:
8 can be fit into 72 9 times, resulting in a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 104679.0
Subtracting 72 from 72 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.

On to step 7:
If we divide 0 by 8, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 104679.0
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.

On to step 8:
0 divided by 8 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 104679.0
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 104679.0 and a remainder of 0.0.
