837857 ÷ 8 
The aim is to understand the frequency of 8 in 837857.

On to step 1:
If we divide 8 by 8, we get 1 and a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 8 from 8 and we're left with 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 8

On to step 2:
If we divide 3 by 8, we get 0 and 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.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 8

Moving on to step 3:
If we divide 37 by 8, we get 4 and a remainder of 5.
Record the quotient 4 as the next digit in the result. 
Result so far: 104.0
If we take 32 away from 37, we end up with 5.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 8

Let's proceed to step 4:
8 goes into 58 7 times with a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 1047.0
Deduct 56 from 58 and we're left with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 8

On to step 5:
8 goes into 25 3 times with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 10473.0
If we take 24 away from 25, we end up with 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 8

Going ahead to step 6:
If we divide 17 by 8, we get 2 and a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 104732.0
Subtract 16 from 17 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
10 divided by 8 is 1 with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 104732.1
If we take 8 away from 10, we end up 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 8:
8 goes into 20 2 times with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 104732.12
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.

Let's proceed to step 9:
If we divide 40 by 8, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 104732.125
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.

Advancing to step 10:
If we divide 0 by 8, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 104732.125
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.

Moving on 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: 104732.125
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 final outcome is 104732.125, with a leftover of 0.0.
