We look at the division of 87888325 by 912 
The aim is to understand the frequency of 912 in 87888325.

On to step 1:
8 divided by 912 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 912

On to step 2:
912 can be fit into 87 0 times, resulting in a remainder of 87.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 87, we get 87.
Bring next digit (8) of the dividend behind the 87 and repeat the process: 878 / 912

Going ahead to step 3:
If we divide 878 by 912, we get 0 and a remainder of 878.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 878 to get 878.
Grab the next digit (8) from the dividend, add it to 878, then carry on: 8788 / 912

On to step 4:
When dividing 8788 by 912, we get 9 with a remainder of 580.
The next digit of our result is 9. 
Result so far: 9.0
If we take 8208 away from 8788, we end up with 580.
Take the next digit (8) from the dividend and append it to 580, then repeat: 5808 / 912

Advancing to step 5:
912 goes into 5808 6 times with a remainder of 336.
Record the quotient 6 as the next digit in the result. 
Result so far: 96.0
The remainder is 336 after subtracting 5472 from 5808.
Append the next digit (3) from the dividend to 336 and continue with: 3363 / 912

Advancing to step 6:
912 goes into 3363 3 times with a remainder of 627.
Use 3 as the next digit of our solution. 
Result so far: 963.0
The remainder is 627 after subtracting 2736 from 3363.
Grab the next digit (2) from the dividend, add it to 627, then carry on: 6272 / 912

Going ahead to step 7:
912 can be fit into 6272 6 times, resulting in a remainder of 800.
Put 6 as the next digit of the answer. 
Result so far: 9636.0
The remainder is 800 after subtracting 5472 from 6272.
Take the next digit (5) from the dividend and append it to 800, then repeat: 8005 / 912

Advancing to step 8:
912 can be fit into 8005 8 times, resulting in a remainder of 709.
Use 8 as the next digit of our solution. 
Result so far: 96368.0
Deduct 7296 from 8005 and we're left with 709.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7090, and continue the process.

Moving on to step 9:
7090 divided by 912 is 7 with a remainder of 706.
Record the quotient 7 as the next digit in the result. 
Result so far: 96368.7
The remainder is 706 after subtracting 6384 from 7090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7060, and continue the process.

Advancing to step 10:
If we divide 7060 by 912, we get 7 and a remainder of 676.
Use 7 as the next digit of our solution. 
Result so far: 96368.77
If we take 6384 away from 7060, we end up with 676.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6760, and continue the process.

The quotient of the division is 96368.77, and the remainder is 0.676.
