89487221 divided by 824 
The aim is to understand the frequency of 824 in 89487221.

Advancing to step 1:
824 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 824

Let's proceed to step 2:
The number 824 fits into 89 0 times, leaving a remainder of 89.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 89 after subtracting 0 from 89.
Append the next digit (4) from the dividend to 89 and continue with: 894 / 824

Let's proceed to step 3:
824 can be fit into 894 1 times, resulting in a remainder of 70.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 824 from 894 leaves us with 70.
Take the next digit (8) from the dividend and append it to 70, then repeat: 708 / 824

Going ahead to step 4:
708 divided by 824 is 0 with a remainder of 708.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we subtract 0 from 708, we get 708.
Append the next digit (7) from the dividend to 708 and continue with: 7087 / 824

Let's proceed to step 5:
7087 divided by 824 is 8 with a remainder of 495.
Use 8 as the next digit of our solution. 
Result so far: 108.0
Deduct 6592 from 7087 and we're left with 495.
Take the next digit (2) from the dividend and append it to 495, then repeat: 4952 / 824

Advancing to step 6:
When dividing 4952 by 824, we get 6 with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 1086.0
Subtract 4944 from 4952 to get 8.
Take the next digit (2) from the dividend and append it to 8, then repeat: 82 / 824

Going ahead to step 7:
824 goes into 82 0 times with a remainder of 82.
Write down 0 as next digit of the result. 
Result so far: 10860.0
Deduct 0 from 82 and we're left with 82.
Take the next digit (1) from the dividend and append it to 82, then repeat: 821 / 824

Let's proceed to step 8:
824 goes into 821 0 times with a remainder of 821.
Write down 0 as next digit of the result. 
Result so far: 108600.0
Subtract 0 from 821 to get 821.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8210, and continue the process.

Moving on to step 9:
If we divide 8210 by 824, we get 9 and a remainder of 794.
Write down 9 as next digit of the result. 
Result so far: 108600.9
The remainder is 794 after subtracting 7416 from 8210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7940, and continue the process.

Advancing to step 10:
The number 824 fits into 7940 9 times, leaving a remainder of 524.
Put 9 as the next digit of the answer. 
Result so far: 108600.99
Deduct 7416 from 7940 and we're left with 524.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

The final result is 108600.99 with a remainder of 0.524.
