537751 divided by 87 
The aim is to understand the frequency of 87 in 537751.

Step 1:
The number 87 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 87

Advancing to step 2:
87 goes into 53 0 times with a remainder of 53.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 53 to get 53.
Grab the next digit (7) from the dividend, add it to 53, then carry on: 537 / 87

Step 3:
If we divide 537 by 87, we get 6 and a remainder of 15.
The next digit of our result is 6. 
Result so far: 6.0
Deduct 522 from 537 and we're left with 15.
Append the next digit (7) from the dividend to 15 and continue with: 157 / 87

Moving on to step 4:
157 divided by 87 is 1 with a remainder of 70.
Write down 1 as next digit of the result. 
Result so far: 61.0
Deduct 87 from 157 and we're left with 70.
Fetch the next digit (5) from the dividend, attach it to 70 and continue: 705 / 87

The number 8 becomes the next digit in our result. 
Result so far: 618.0
Deduct 696 from 705 and we're left with 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 87

Moving on to step 6:
91 divided by 87 is 1 with a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 6181.0
If we take 87 away from 91, we end up 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.

Advancing to step 7:
The number 87 fits into 40 0 times, leaving a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 6181.0
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 8:
87 can be fit into 400 4 times, resulting in a remainder of 52.
The next digit of our result is 4. 
Result so far: 6181.04
If we take 348 away from 400, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 9:
87 can be fit into 520 5 times, resulting in a remainder of 85.
Put 5 as the next digit of the answer. 
Result so far: 6181.045
Deduct 435 from 520 and we're left 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.

Step 10:
87 can be fit into 850 9 times, resulting in a remainder of 67.
Put 9 as the next digit of the answer. 
Result so far: 6181.0459
Subtract 783 from 850 to 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.

On to step 11:
87 can be fit into 670 7 times, resulting in a remainder of 61.
Record the quotient 7 as the next digit in the result. 
Result so far: 6181.04597
Subtracting 609 from 670 leaves us 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.

On to step 12:
87 can be fit into 610 7 times, resulting in a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 6181.045977
Deduct 609 from 610 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.

Our division results in 6181.045977 with a remaining 1e-07.
