712029 ÷ 87 
The aim is to understand the frequency of 87 in 712029.

Step 1:
If we divide 7 by 87, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 87

Let's proceed to step 2:
When dividing 71 by 87, we get 0 with a remainder of 71.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 71 after subtracting 0 from 71.
Grab the next digit (2) from the dividend, add it to 71, then carry on: 712 / 87

Let's proceed to step 3:
When dividing 712 by 87, we get 8 with a remainder of 16.
The next digit of our result is 8. 
Result so far: 8.0
If we subtract 696 from 712, we get 16.
Append the next digit (0) from the dividend to 16 and continue with: 160 / 87

Step 4:
160 divided by 87 is 1 with a remainder of 73.
The number 1 becomes the next digit in our result. 
Result so far: 81.0
Subtracting 87 from 160 leaves us with 73.
Append the next digit (2) from the dividend to 73 and continue with: 732 / 87

Advancing to step 5:
732 divided by 87 is 8 with a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 818.0
Subtracting 696 from 732 leaves us with 36.
Append the next digit (9) from the dividend to 36 and continue with: 369 / 87

On to step 6:
The number 87 fits into 369 4 times, leaving a remainder of 21.
Write down 4 as next digit of the result. 
Result so far: 8184.0
Deduct 348 from 369 and we're left with 21.
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:
87 can be fit into 210 2 times, resulting in a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 8184.2
Deduct 174 from 210 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 8:
The number 87 fits into 360 4 times, leaving a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 8184.24
Deduct 348 from 360 and we're left 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.

Moving on to step 9:
87 goes into 120 1 times with a remainder of 33.
Record the quotient 1 as the next digit in the result. 
Result so far: 8184.241
If we subtract 87 from 120, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 10:
When dividing 330 by 87, we get 3 with a remainder of 69.
Use 3 as the next digit of our solution. 
Result so far: 8184.2413
If we subtract 261 from 330, we get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 11:
If we divide 690 by 87, we get 7 and a remainder of 81.
The next digit of our result is 7. 
Result so far: 8184.24137
If we subtract 609 from 690, we get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

On to step 12:
When dividing 810 by 87, we get 9 with a remainder of 27.
The number 9 becomes the next digit in our result. 
Result so far: 8184.241379
Deduct 783 from 810 and we're left 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.

On to step 13:
The number 87 fits into 270 3 times, leaving a remainder of 9.
Use 3 as the next digit of our solution. 
Result so far: 8184.2413793
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.

Moving on to step 14:
90 divided by 87 is 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 8184.24137931
If we take 87 away from 90, we end up with 3.
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 8184.24137931 with a remaining 3e-09.
