901202 ÷ 87 
The aim is to understand the frequency of 87 in 901202.

On to step 1:
87 can be fit into 9 0 times, resulting in a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 87

On to step 2:
90 divided by 87 is 1 with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 87 from 90 to get 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 87

Moving on to step 3:
87 goes into 31 0 times with a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtract 0 from 31 to get 31.
Append the next digit (2) from the dividend to 31 and continue with: 312 / 87

Going ahead to step 4:
If we divide 312 by 87, we get 3 and a remainder of 51.
Use 3 as the next digit of our solution. 
Result so far: 103.0
Subtracting 261 from 312 leaves us with 51.
Take the next digit (0) from the dividend and append it to 51, then repeat: 510 / 87

On to step 5:
The number 87 fits into 510 5 times, leaving a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 1035.0
If we subtract 435 from 510, we get 75.
Fetch the next digit (2) from the dividend, attach it to 75 and continue: 752 / 87

Moving on to step 6:
87 can be fit into 752 8 times, resulting in a remainder of 56.
The next digit of our result is 8. 
Result so far: 10358.0
Deduct 696 from 752 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 7:
87 goes into 560 6 times with a remainder of 38.
The next digit of our result is 6. 
Result so far: 10358.6
If we take 522 away from 560, 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.

Let's proceed to step 8:
The number 87 fits into 380 4 times, leaving a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 10358.64
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.

Step 9:
87 can be fit into 320 3 times, resulting in a remainder of 59.
Write down 3 as next digit of the result. 
Result so far: 10358.643
The remainder is 59 after subtracting 261 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

On to step 10:
If we divide 590 by 87, we get 6 and a remainder of 68.
Record the quotient 6 as the next digit in the result. 
Result so far: 10358.6436
Subtracting 522 from 590 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 11:
87 can be fit into 680 7 times, resulting in a remainder of 71.
Record the quotient 7 as the next digit in the result. 
Result so far: 10358.64367
Deduct 609 from 680 and we're left with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Going ahead to step 12:
If we divide 710 by 87, we get 8 and a remainder of 14.
Put 8 as the next digit of the answer. 
Result so far: 10358.643678
Subtract 696 from 710 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 13:
If we divide 140 by 87, we get 1 and a remainder of 53.
Write down 1 as next digit of the result. 
Result so far: 10358.6436781
The remainder is 53 after subtracting 87 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Moving on to step 14:
87 can be fit into 530 6 times, resulting in a remainder of 8.
The next digit of our result is 6. 
Result so far: 10358.64367816
Subtracting 522 from 530 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final result is 10358.64367816 with a remainder of 8e-09.
