Let's divide 372807 by 87
The aim is to understand the frequency of 87 in 372807.

Advancing to step 1:
3 divided by 87 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 87

Moving on to step 2:
When dividing 37 by 87, we get 0 with a remainder of 37.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 37 after subtracting 0 from 37.
Fetch the next digit (2) from the dividend, attach it to 37 and continue: 372 / 87

Moving on to step 3:
87 can be fit into 372 4 times, resulting in a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 348 from 372 to get 24.
Include the next digit (8) from the dividend after 24, then repeat: 248 / 87

Moving on to step 4:
When dividing 248 by 87, we get 2 with a remainder of 74.
The number 2 becomes the next digit in our result. 
Result so far: 42.0
If we take 174 away from 248, we end up with 74.
Append the next digit (0) from the dividend to 74 and continue with: 740 / 87

Let's proceed to step 5:
The number 87 fits into 740 8 times, leaving a remainder of 44.
Write down 8 as next digit of the result. 
Result so far: 428.0
If we subtract 696 from 740, we get 44.
Bring next digit (7) of the dividend behind the 44 and repeat the process: 447 / 87

Step 6:
When dividing 447 by 87, we get 5 with a remainder of 12.
Put 5 as the next digit of the answer. 
Result so far: 4285.0
If we subtract 435 from 447, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 7:
120 divided by 87 is 1 with a remainder of 33.
Put 1 as the next digit of the answer. 
Result so far: 4285.1
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 8:
87 goes into 330 3 times with a remainder of 69.
Write down 3 as next digit of the result. 
Result so far: 4285.13
Subtracting 261 from 330 leaves us 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.

On to step 9:
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: 4285.137
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.

Step 10:
When dividing 810 by 87, we get 9 with a remainder of 27.
Use 9 as the next digit of our solution. 
Result so far: 4285.1379
Subtract 783 from 810 to get 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 11:
270 divided by 87 is 3 with a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 4285.13793
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.

On to step 12:
The number 87 fits into 90 1 times, leaving a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 4285.137931
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.

Moving on to step 13:
If we divide 30 by 87, we get 0 and a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 4285.137931
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 14:
87 can be fit into 300 3 times, resulting in a remainder of 39.
The number 3 becomes the next digit in our result. 
Result so far: 4285.13793103
Subtract 261 from 300 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

The quotient of the division is 4285.13793103, and the remainder is 3.9e-08.
