We divide 72763921 by 8
The aim is to understand the frequency of 8 in 72763921.

Step 1:
If we divide 7 by 8, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 8

Going ahead to step 2:
72 divided by 8 is 9 with a remainder of 0.
The next digit of our result is 9. 
Result so far: 9.0
If we take 72 away from 72, we end up with 0.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 8

Step 3:
If we divide 7 by 8, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 90.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (6) from the dividend, add it to 7, then carry on: 76 / 8

Advancing to step 4:
8 goes into 76 9 times with a remainder of 4.
Use 9 as the next digit of our solution. 
Result so far: 909.0
If we take 72 away from 76, we end up with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 8

Moving on to step 5:
43 divided by 8 is 5 with a remainder of 3.
Put 5 as the next digit of the answer. 
Result so far: 9095.0
Subtracting 40 from 43 leaves us with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 8

Moving on to step 6:
If we divide 39 by 8, we get 4 and a remainder of 7.
The number 4 becomes the next digit in our result. 
Result so far: 90954.0
Deduct 32 from 39 and we're left with 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 8

Let's proceed to step 7:
8 goes into 72 9 times with a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 909549.0
Deduct 72 from 72 and we're left with 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 8

Step 8:
If we divide 1 by 8, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 9095490.0
Deduct 0 from 1 and we're left 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.

Advancing to step 9:
When dividing 10 by 8, we get 1 with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 9095490.1
If we subtract 8 from 10, we get 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 10:
8 goes into 20 2 times with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 9095490.12
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.

Going ahead to step 11:
8 goes into 40 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 9095490.125
Deduct 40 from 40 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.

Advancing to step 12:
The number 8 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 9095490.125
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.

Moving on to step 13:
0 divided by 8 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 9095490.125
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 quotient of the division is 9095490.125, and the remainder is 0.0.
