We divide 925121 by 87
The aim is to understand the frequency of 87 in 925121.

Moving on to step 1:
87 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Include the next digit (2) from the dividend after 9, then repeat: 92 / 87

Step 2:
The number 87 fits into 92 1 times, leaving a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 87 from 92 and we're left with 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 87

Advancing to step 3:
The number 87 fits into 55 0 times, leaving a remainder of 55.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
The remainder is 55 after subtracting 0 from 55.
Append the next digit (1) from the dividend to 55 and continue with: 551 / 87

Going ahead to step 4:
87 goes into 551 6 times with a remainder of 29.
Write down 6 as next digit of the result. 
Result so far: 106.0
Deduct 522 from 551 and we're left with 29.
Include the next digit (2) from the dividend after 29, then repeat: 292 / 87

Advancing to step 5:
87 goes into 292 3 times with a remainder of 31.
Use 3 as the next digit of our solution. 
Result so far: 1063.0
Subtracting 261 from 292 leaves us with 31.
Include the next digit (1) from the dividend after 31, then repeat: 311 / 87

Step 6:
87 can be fit into 311 3 times, resulting in a remainder of 50.
The number 3 becomes the next digit in our result. 
Result so far: 10633.0
If we take 261 away from 311, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 7:
If we divide 500 by 87, we get 5 and a remainder of 65.
Record the quotient 5 as the next digit in the result. 
Result so far: 10633.5
If we subtract 435 from 500, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 8:
650 divided by 87 is 7 with a remainder of 41.
The number 7 becomes the next digit in our result. 
Result so far: 10633.57
The remainder is 41 after subtracting 609 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 9:
87 can be fit into 410 4 times, resulting in a remainder of 62.
Use 4 as the next digit of our solution. 
Result so far: 10633.574
Subtract 348 from 410 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 10:
The number 87 fits into 620 7 times, leaving a remainder of 11.
Write down 7 as next digit of the result. 
Result so far: 10633.5747
If we take 609 away from 620, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 11:
The number 87 fits into 110 1 times, leaving a remainder of 23.
Write down 1 as next digit of the result. 
Result so far: 10633.57471
Subtracting 87 from 110 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 12:
If we divide 230 by 87, we get 2 and a remainder of 56.
The next digit of our result is 2. 
Result so far: 10633.574712
The remainder is 56 after subtracting 174 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 13:
If we divide 560 by 87, we get 6 and a remainder of 38.
The number 6 becomes the next digit in our result. 
Result so far: 10633.5747126
Subtracting 522 from 560 leaves us 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.

Step 14:
The number 87 fits into 380 4 times, leaving a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 10633.57471264
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.

The final result is 10633.57471264 with a remainder of 3.2e-08.
