699240 divided by 87 
The aim is to understand the frequency of 87 in 699240.

Let's proceed to step 1:
When dividing 6 by 87, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 87

On to step 2:
If we divide 69 by 87, we get 0 and a remainder of 69.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 69 after subtracting 0 from 69.
Append the next digit (9) from the dividend to 69 and continue with: 699 / 87

On to step 3:
699 divided by 87 is 8 with a remainder of 3.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Deduct 696 from 699 and we're left with 3.
Grab the next digit (2) from the dividend, add it to 3, then carry on: 32 / 87

Moving on to step 4:
87 can be fit into 32 0 times, resulting in a remainder of 32.
Use 0 as the next digit of our solution. 
Result so far: 80.0
If we subtract 0 from 32, we get 32.
Fetch the next digit (4) from the dividend, attach it to 32 and continue: 324 / 87

Moving on to step 5:
If we divide 324 by 87, we get 3 and a remainder of 63.
Put 3 as the next digit of the answer. 
Result so far: 803.0
If we subtract 261 from 324, we get 63.
Fetch the next digit (0) from the dividend, attach it to 63 and continue: 630 / 87

Let's proceed to step 6:
If we divide 630 by 87, we get 7 and a remainder of 21.
Write down 7 as next digit of the result. 
Result so far: 8037.0
The remainder is 21 after subtracting 609 from 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 7:
The number 87 fits into 210 2 times, leaving a remainder of 36.
The next digit of our result is 2. 
Result so far: 8037.2
Subtract 174 from 210 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 8:
When dividing 360 by 87, we get 4 with a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 8037.24
If we take 348 away from 360, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 9:
If we divide 120 by 87, we get 1 and a remainder of 33.
Record the quotient 1 as the next digit in the result. 
Result so far: 8037.241
The remainder is 33 after subtracting 87 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 10:
When dividing 330 by 87, we get 3 with a remainder of 69.
The next digit of our result is 3. 
Result so far: 8037.2413
Deduct 261 from 330 and we're left with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Going ahead to step 11:
If we divide 690 by 87, we get 7 and a remainder of 81.
Record the quotient 7 as the next digit in the result. 
Result so far: 8037.24137
Subtracting 609 from 690 leaves us with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Advancing to step 12:
If we divide 810 by 87, we get 9 and a remainder of 27.
Put 9 as the next digit of the answer. 
Result so far: 8037.241379
Subtracting 783 from 810 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 13:
If we divide 270 by 87, we get 3 and a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 8037.2413793
Subtract 261 from 270 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 14:
If we divide 90 by 87, we get 1 and a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 8037.24137931
The remainder is 3 after subtracting 87 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Our division results in 8037.24137931 with a remaining 3e-09.
