We look at the division of 853328 by 87 
The aim is to understand the frequency of 87 in 853328.

Moving on to step 1:
The number 87 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 87

On to step 2:
85 divided by 87 is 0 with a remainder of 85.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 85 leaves us with 85.
Grab the next digit (3) from the dividend, add it to 85, then carry on: 853 / 87

Moving on to step 3:
If we divide 853 by 87, we get 9 and a remainder of 70.
Write down 9 as next digit of the result. 
Result so far: 9.0
The remainder is 70 after subtracting 783 from 853.
Append the next digit (3) from the dividend to 70 and continue with: 703 / 87

Step 4:
87 can be fit into 703 8 times, resulting in a remainder of 7.
The next digit of our result is 8. 
Result so far: 98.0
The remainder is 7 after subtracting 696 from 703.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 87

Moving on to step 5:
The number 87 fits into 72 0 times, leaving a remainder of 72.
Record the quotient 0 as the next digit in the result. 
Result so far: 980.0
The remainder is 72 after subtracting 0 from 72.
Fetch the next digit (8) from the dividend, attach it to 72 and continue: 728 / 87

Let's proceed to step 6:
87 can be fit into 728 8 times, resulting in a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 9808.0
Subtract 696 from 728 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 7:
320 divided by 87 is 3 with a remainder of 59.
Put 3 as the next digit of the answer. 
Result so far: 9808.3
If we subtract 261 from 320, we get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Let's proceed to step 8:
When dividing 590 by 87, we get 6 with a remainder of 68.
Put 6 as the next digit of the answer. 
Result so far: 9808.36
If we subtract 522 from 590, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 9:
87 can be fit into 680 7 times, resulting in a remainder of 71.
The number 7 becomes the next digit in our result. 
Result so far: 9808.367
Deduct 609 from 680 and we're left with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Moving on to step 10:
If we divide 710 by 87, we get 8 and a remainder of 14.
Write down 8 as next digit of the result. 
Result so far: 9808.3678
Subtracting 696 from 710 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 11:
When dividing 140 by 87, we get 1 with a remainder of 53.
Put 1 as the next digit of the answer. 
Result so far: 9808.36781
Subtracting 87 from 140 leaves us with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

On to step 12:
When dividing 530 by 87, we get 6 with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 9808.367816
The remainder is 8 after subtracting 522 from 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 13:
The number 87 fits into 80 0 times, leaving a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 9808.367816
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 14:
The number 87 fits into 800 9 times, leaving a remainder of 17.
The number 9 becomes the next digit in our result. 
Result so far: 9808.36781609
The remainder is 17 after subtracting 783 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

The quotient of the division is 9808.36781609, and the remainder is 1.7e-08.
