Let's divide 837547 by 87
The aim is to understand the frequency of 87 in 837547.

Moving on to step 1:
If we divide 8 by 87, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 87

Going ahead to step 2:
87 can be fit into 83 0 times, resulting in a remainder of 83.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 83, we get 83.
Append the next digit (7) from the dividend to 83 and continue with: 837 / 87

Going ahead to step 3:
87 can be fit into 837 9 times, resulting in a remainder of 54.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtract 783 from 837 to get 54.
Include the next digit (5) from the dividend after 54, then repeat: 545 / 87

On to step 4:
If we divide 545 by 87, we get 6 and a remainder of 23.
Write down 6 as next digit of the result. 
Result so far: 96.0
The remainder is 23 after subtracting 522 from 545.
Grab the next digit (4) from the dividend, add it to 23, then carry on: 234 / 87

Going ahead to step 5:
87 goes into 234 2 times with a remainder of 60.
Write down 2 as next digit of the result. 
Result so far: 962.0
Subtract 174 from 234 to get 60.
Grab the next digit (7) from the dividend, add it to 60, then carry on: 607 / 87

Step 6:
607 divided by 87 is 6 with a remainder of 85.
Record the quotient 6 as the next digit in the result. 
Result so far: 9626.0
Subtracting 522 from 607 leaves us with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Going ahead to step 7:
When dividing 850 by 87, we get 9 with a remainder of 67.
The next digit of our result is 9. 
Result so far: 9626.9
If we subtract 783 from 850, we get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Step 8:
87 goes into 670 7 times with a remainder of 61.
Record the quotient 7 as the next digit in the result. 
Result so far: 9626.97
If we take 609 away from 670, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 9:
If we divide 610 by 87, we get 7 and a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 9626.977
Subtracting 609 from 610 leaves us 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.

The quotient of the division is 9626.977, and the remainder is 0.0001.
