We're dividing 551772 by 87 
The aim is to understand the frequency of 87 in 551772.

Let's proceed to step 1:
5 divided by 87 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 87

Step 2:
When dividing 55 by 87, we get 0 with a remainder of 55.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 55, we end up with 55.
Append the next digit (1) from the dividend to 55 and continue with: 551 / 87

Going ahead to step 3:
The number 87 fits into 551 6 times, leaving a remainder of 29.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we subtract 522 from 551, we get 29.
Grab the next digit (7) from the dividend, add it to 29, then carry on: 297 / 87

Let's proceed to step 4:
87 goes into 297 3 times with a remainder of 36.
Use 3 as the next digit of our solution. 
Result so far: 63.0
If we subtract 261 from 297, we get 36.
Grab the next digit (7) from the dividend, add it to 36, then carry on: 367 / 87

Moving on to step 5:
When dividing 367 by 87, we get 4 with a remainder of 19.
Record the quotient 4 as the next digit in the result. 
Result so far: 634.0
Deduct 348 from 367 and we're left with 19.
Include the next digit (2) from the dividend after 19, then repeat: 192 / 87

Going ahead to step 6:
If we divide 192 by 87, we get 2 and a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 6342.0
If we take 174 away from 192, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 7:
180 divided by 87 is 2 with a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 6342.2
Subtract 174 from 180 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 8:
60 divided by 87 is 0 with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 6342.2
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 9:
When dividing 600 by 87, we get 6 with a remainder of 78.
Use 6 as the next digit of our solution. 
Result so far: 6342.206
Subtract 522 from 600 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Advancing to step 10:
87 can be fit into 780 8 times, resulting in a remainder of 84.
Put 8 as the next digit of the answer. 
Result so far: 6342.2068
If we take 696 away from 780, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 11:
87 goes into 840 9 times with a remainder of 57.
The next digit of our result is 9. 
Result so far: 6342.20689
If we subtract 783 from 840, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Let's proceed to step 12:
87 goes into 570 6 times with a remainder of 48.
Put 6 as the next digit of the answer. 
Result so far: 6342.206896
If we subtract 522 from 570, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 13:
If we divide 480 by 87, we get 5 and a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 6342.2068965
If we take 435 away from 480, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 14:
If we divide 450 by 87, we get 5 and a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 6342.20689655
If we take 435 away from 450, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The quotient of the division is 6342.20689655, and the remainder is 1.5e-08.
