845574 ÷ 87 
The aim is to understand the frequency of 87 in 845574.

Let's proceed to step 1:
When dividing 8 by 87, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 87

Step 2:
87 can be fit into 84 0 times, resulting in a remainder of 84.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 84 to get 84.
Append the next digit (5) from the dividend to 84 and continue with: 845 / 87

Let's proceed to step 3:
87 can be fit into 845 9 times, resulting in a remainder of 62.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtracting 783 from 845 leaves us with 62.
Grab the next digit (5) from the dividend, add it to 62, then carry on: 625 / 87

On to step 4:
If we divide 625 by 87, we get 7 and a remainder of 16.
The number 7 becomes the next digit in our result. 
Result so far: 97.0
If we subtract 609 from 625, we get 16.
Append the next digit (7) from the dividend to 16 and continue with: 167 / 87

Step 5:
87 can be fit into 167 1 times, resulting in a remainder of 80.
The number 1 becomes the next digit in our result. 
Result so far: 971.0
Subtracting 87 from 167 leaves us with 80.
Bring next digit (4) of the dividend behind the 80 and repeat the process: 804 / 87

Moving on to step 6:
When dividing 804 by 87, we get 9 with a remainder of 21.
Put 9 as the next digit of the answer. 
Result so far: 9719.0
Deduct 783 from 804 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.

On to step 7:
When dividing 210 by 87, we get 2 with a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 9719.2
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.

On to step 8:
If we divide 360 by 87, we get 4 and a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 9719.24
Subtracting 348 from 360 leaves us 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.

Let's proceed to step 9:
When dividing 120 by 87, we get 1 with a remainder of 33.
Write down 1 as next digit of the result. 
Result so far: 9719.241
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.

On to step 10:
The number 87 fits into 330 3 times, leaving a remainder of 69.
The number 3 becomes the next digit in our result. 
Result so far: 9719.2413
Subtract 261 from 330 to 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.

Going ahead to step 11:
87 can be fit into 690 7 times, resulting in a remainder of 81.
The number 7 becomes the next digit in our result. 
Result so far: 9719.24137
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.

Moving on to step 12:
87 goes into 810 9 times with a remainder of 27.
Use 9 as the next digit of our solution. 
Result so far: 9719.241379
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.

Moving on to step 13:
87 can be fit into 270 3 times, resulting in a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 9719.2413793
Subtracting 261 from 270 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 14:
87 goes into 90 1 times with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 9719.24137931
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 9719.24137931 with a remaining 3e-09.
