We look at the division of 625516 by 87 
The aim is to understand the frequency of 87 in 625516.

Let's proceed to step 1:
6 divided by 87 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 87

Going ahead to step 2:
When dividing 62 by 87, we get 0 with a remainder of 62.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 62 after subtracting 0 from 62.
Append the next digit (5) from the dividend to 62 and continue with: 625 / 87

Going ahead to step 3:
625 divided by 87 is 7 with a remainder of 16.
Write down 7 as next digit of the result. 
Result so far: 7.0
The remainder is 16 after subtracting 609 from 625.
Fetch the next digit (5) from the dividend, attach it to 16 and continue: 165 / 87

Moving on to step 4:
87 can be fit into 165 1 times, resulting in a remainder of 78.
Use 1 as the next digit of our solution. 
Result so far: 71.0
If we take 87 away from 165, we end up with 78.
Fetch the next digit (1) from the dividend, attach it to 78 and continue: 781 / 87

Advancing to step 5:
87 can be fit into 781 8 times, resulting in a remainder of 85.
The next digit of our result is 8. 
Result so far: 718.0
If we take 696 away from 781, we end up with 85.
Grab the next digit (6) from the dividend, add it to 85, then carry on: 856 / 87

Step 6:
When dividing 856 by 87, we get 9 with a remainder of 73.
Use 9 as the next digit of our solution. 
Result so far: 7189.0
Deduct 783 from 856 and we're left with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Step 7:
The number 87 fits into 730 8 times, leaving a remainder of 34.
The number 8 becomes the next digit in our result. 
Result so far: 7189.8
If we subtract 696 from 730, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 8:
The number 87 fits into 340 3 times, leaving a remainder of 79.
Put 3 as the next digit of the answer. 
Result so far: 7189.83
Deduct 261 from 340 and we're left with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Going ahead to step 9:
87 can be fit into 790 9 times, resulting in a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 7189.839
Subtracting 783 from 790 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 10:
When dividing 70 by 87, we get 0 with a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 7189.839
Subtract 0 from 70 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 11:
When dividing 700 by 87, we get 8 with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 7189.83908
The remainder is 4 after subtracting 696 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 12:
87 can be fit into 40 0 times, resulting in a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 7189.83908
If we take 0 away from 40, we end up 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.

Step 13:
The number 87 fits into 400 4 times, leaving a remainder of 52.
Record the quotient 4 as the next digit in the result. 
Result so far: 7189.8390804
If we subtract 348 from 400, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 14:
If we divide 520 by 87, we get 5 and a remainder of 85.
Record the quotient 5 as the next digit in the result. 
Result so far: 7189.83908045
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.

The final outcome is 7189.83908045, with a leftover of 8.5e-08.
