We divide 663848 by 87
The aim is to understand the frequency of 87 in 663848.

Step 1:
6 divided by 87 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 87

Let's proceed to step 2:
87 can be fit into 66 0 times, resulting in a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Include the next digit (3) from the dividend after 66, then repeat: 663 / 87

On to step 3:
87 can be fit into 663 7 times, resulting in a remainder of 54.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtract 609 from 663 to get 54.
Grab the next digit (8) from the dividend, add it to 54, then carry on: 548 / 87

On to step 4:
If we divide 548 by 87, we get 6 and a remainder of 26.
The next digit of our result is 6. 
Result so far: 76.0
Subtract 522 from 548 to get 26.
Take the next digit (4) from the dividend and append it to 26, then repeat: 264 / 87

Step 5:
87 goes into 264 3 times with a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 763.0
Subtracting 261 from 264 leaves us with 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 87

Advancing to step 6:
87 goes into 38 0 times with a remainder of 38.
Write down 0 as next digit of the result. 
Result so far: 7630.0
If we take 0 away from 38, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 7:
87 goes into 380 4 times with a remainder of 32.
Write down 4 as next digit of the result. 
Result so far: 7630.4
If we subtract 348 from 380, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 8:
If we divide 320 by 87, we get 3 and a remainder of 59.
Write down 3 as next digit of the result. 
Result so far: 7630.43
Subtract 261 from 320 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Going ahead to step 9:
When dividing 590 by 87, we get 6 with a remainder of 68.
Use 6 as the next digit of our solution. 
Result so far: 7630.436
Subtract 522 from 590 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 10:
When dividing 680 by 87, we get 7 with a remainder of 71.
Use 7 as the next digit of our solution. 
Result so far: 7630.4367
The remainder is 71 after subtracting 609 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Advancing to step 11:
The number 87 fits into 710 8 times, leaving a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 7630.43678
If we take 696 away from 710, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 12:
The number 87 fits into 140 1 times, leaving a remainder of 53.
Use 1 as the next digit of our solution. 
Result so far: 7630.436781
If we subtract 87 from 140, we get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

On to step 13:
87 can be fit into 530 6 times, resulting in a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 7630.4367816
If we subtract 522 from 530, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 14:
80 divided by 87 is 0 with a remainder of 80.
The next digit of our result is 0. 
Result so far: 7630.4367816
Subtracting 0 from 80 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The quotient of the division is 7630.4367816, and the remainder is 8e-08.
