We divide 637122 by 87
The aim is to understand the frequency of 87 in 637122.

On to step 1:
87 goes into 6 0 times 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.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 87

On to step 2:
63 divided by 87 is 0 with a remainder of 63.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 63 to get 63.
Append the next digit (7) from the dividend to 63 and continue with: 637 / 87

Moving on to step 3:
When dividing 637 by 87, we get 7 with a remainder of 28.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtracting 609 from 637 leaves us with 28.
Append the next digit (1) from the dividend to 28 and continue with: 281 / 87

Let's proceed to step 4:
87 goes into 281 3 times with a remainder of 20.
Use 3 as the next digit of our solution. 
Result so far: 73.0
Subtract 261 from 281 to get 20.
Bring next digit (2) of the dividend behind the 20 and repeat the process: 202 / 87

Let's proceed to step 5:
If we divide 202 by 87, we get 2 and a remainder of 28.
The next digit of our result is 2. 
Result so far: 732.0
Subtracting 174 from 202 leaves us with 28.
Append the next digit (2) from the dividend to 28 and continue with: 282 / 87

Let's proceed to step 6:
The number 87 fits into 282 3 times, leaving a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 7323.0
Deduct 261 from 282 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:
210 divided by 87 is 2 with a remainder of 36.
The number 2 becomes the next digit in our result. 
Result so far: 7323.2
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.

Advancing 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: 7323.24
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.

Advancing to step 9:
87 can be fit into 120 1 times, resulting in a remainder of 33.
Write down 1 as next digit of the result. 
Result so far: 7323.241
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.

Going ahead to step 10:
87 can be fit into 330 3 times, resulting in a remainder of 69.
The next digit of our result is 3. 
Result so far: 7323.2413
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.

Moving on to step 11:
When dividing 690 by 87, we get 7 with a remainder of 81.
Write down 7 as next digit of the result. 
Result so far: 7323.24137
If we take 609 away from 690, we end up 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:
87 goes into 810 9 times with a remainder of 27.
Put 9 as the next digit of the answer. 
Result so far: 7323.241379
If we subtract 783 from 810, we 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 13:
87 can be fit into 270 3 times, resulting in a remainder of 9.
Use 3 as the next digit of our solution. 
Result so far: 7323.2413793
The remainder is 9 after subtracting 261 from 270.
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.
Record the quotient 1 as the next digit in the result. 
Result so far: 7323.24137931
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.

The quotient of the division is 7323.24137931, and the remainder is 3e-09.
