943110 divided by 87 
The aim is to understand the frequency of 87 in 943110.

Advancing to step 1:
The number 87 fits into 9 0 times, leaving 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.
Grab the next digit (4) from the dividend, add it to 9, then carry on: 94 / 87

Moving on to step 2:
If we divide 94 by 87, we get 1 and a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 87 from 94 leaves us with 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 87

Going ahead to step 3:
87 goes into 73 0 times with a remainder of 73.
Write down 0 as next digit of the result. 
Result so far: 10.0
Deduct 0 from 73 and we're left with 73.
Fetch the next digit (1) from the dividend, attach it to 73 and continue: 731 / 87

Advancing to step 4:
If we divide 731 by 87, we get 8 and a remainder of 35.
Write down 8 as next digit of the result. 
Result so far: 108.0
The remainder is 35 after subtracting 696 from 731.
Include the next digit (1) from the dividend after 35, then repeat: 351 / 87

Step 5:
87 goes into 351 4 times with a remainder of 3.
The next digit of our result is 4. 
Result so far: 1084.0
The remainder is 3 after subtracting 348 from 351.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 87

Advancing to step 6:
30 divided by 87 is 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 10840.0
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 7:
If we divide 300 by 87, we get 3 and a remainder of 39.
Use 3 as the next digit of our solution. 
Result so far: 10840.3
The remainder is 39 after subtracting 261 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 8:
If we divide 390 by 87, we get 4 and a remainder of 42.
The next digit of our result is 4. 
Result so far: 10840.34
Subtract 348 from 390 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 9:
If we divide 420 by 87, we get 4 and a remainder of 72.
Use 4 as the next digit of our solution. 
Result so far: 10840.344
Subtract 348 from 420 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

After the division, we end up with 10840.344 and a remainder of 0.0072.
