Let's divide 686261 by 87
The aim is to understand the frequency of 87 in 686261.

Moving on to step 1:
The number 87 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 87

Moving on to step 2:
87 goes into 68 0 times with a remainder of 68.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 68 after subtracting 0 from 68.
Grab the next digit (6) from the dividend, add it to 68, then carry on: 686 / 87

On to step 3:
87 can be fit into 686 7 times, resulting in a remainder of 77.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we take 609 away from 686, we end up with 77.
Grab the next digit (2) from the dividend, add it to 77, then carry on: 772 / 87

On to step 4:
When dividing 772 by 87, we get 8 with a remainder of 76.
Use 8 as the next digit of our solution. 
Result so far: 78.0
If we take 696 away from 772, we end up with 76.
Bring next digit (6) of the dividend behind the 76 and repeat the process: 766 / 87

Moving on to step 5:
When dividing 766 by 87, we get 8 with a remainder of 70.
Record the quotient 8 as the next digit in the result. 
Result so far: 788.0
Deduct 696 from 766 and we're left with 70.
Include the next digit (1) from the dividend after 70, then repeat: 701 / 87

Going ahead to step 6:
If we divide 701 by 87, we get 8 and a remainder of 5.
The next digit of our result is 8. 
Result so far: 7888.0
Deduct 696 from 701 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 7:
87 goes into 50 0 times with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 7888.0
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 8:
When dividing 500 by 87, we get 5 with a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 7888.05
The remainder is 65 after subtracting 435 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Step 9:
When dividing 650 by 87, we get 7 with a remainder of 41.
Use 7 as the next digit of our solution. 
Result so far: 7888.057
Subtract 609 from 650 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 10:
When dividing 410 by 87, we get 4 with a remainder of 62.
Write down 4 as next digit of the result. 
Result so far: 7888.0574
The remainder is 62 after subtracting 348 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 11:
87 goes into 620 7 times with a remainder of 11.
Record the quotient 7 as the next digit in the result. 
Result so far: 7888.05747
The remainder is 11 after subtracting 609 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 12:
The number 87 fits into 110 1 times, leaving a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 7888.057471
Subtracting 87 from 110 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 13:
230 divided by 87 is 2 with a remainder of 56.
Use 2 as the next digit of our solution. 
Result so far: 7888.0574712
Subtract 174 from 230 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 14:
560 divided by 87 is 6 with a remainder of 38.
The number 6 becomes the next digit in our result. 
Result so far: 7888.05747126
The remainder is 38 after subtracting 522 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Our division results in 7888.05747126 with a remaining 3.8e-08.
