We look at the division of 92415143 by 987 
The aim is to understand the frequency of 987 in 92415143.

Going ahead to step 1:
987 goes into 9 0 times with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Include the next digit (2) from the dividend after 9, then repeat: 92 / 987

Moving on to step 2:
When dividing 92 by 987, we get 0 with a remainder of 92.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 92, we get 92.
Grab the next digit (4) from the dividend, add it to 92, then carry on: 924 / 987

Let's proceed to step 3:
987 goes into 924 0 times with a remainder of 924.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 924, we end up with 924.
Fetch the next digit (1) from the dividend, attach it to 924 and continue: 9241 / 987

Advancing to step 4:
The number 987 fits into 9241 9 times, leaving a remainder of 358.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtracting 8883 from 9241 leaves us with 358.
Take the next digit (5) from the dividend and append it to 358, then repeat: 3585 / 987

Step 5:
When dividing 3585 by 987, we get 3 with a remainder of 624.
Write down 3 as next digit of the result. 
Result so far: 93.0
If we subtract 2961 from 3585, we get 624.
Take the next digit (1) from the dividend and append it to 624, then repeat: 6241 / 987

Step 6:
If we divide 6241 by 987, we get 6 and a remainder of 319.
The next digit of our result is 6. 
Result so far: 936.0
The remainder is 319 after subtracting 5922 from 6241.
Fetch the next digit (4) from the dividend, attach it to 319 and continue: 3194 / 987

On to step 7:
If we divide 3194 by 987, we get 3 and a remainder of 233.
The next digit of our result is 3. 
Result so far: 9363.0
If we take 2961 away from 3194, we end up with 233.
Bring next digit (3) of the dividend behind the 233 and repeat the process: 2333 / 987

Step 8:
987 goes into 2333 2 times with a remainder of 359.
The number 2 becomes the next digit in our result. 
Result so far: 93632.0
The remainder is 359 after subtracting 1974 from 2333.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3590, and continue the process.

Step 9:
If we divide 3590 by 987, we get 3 and a remainder of 629.
Use 3 as the next digit of our solution. 
Result so far: 93632.3
Subtract 2961 from 3590 to get 629.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6290, and continue the process.

Advancing to step 10:
The number 987 fits into 6290 6 times, leaving a remainder of 368.
Use 6 as the next digit of our solution. 
Result so far: 93632.36
Deduct 5922 from 6290 and we're left with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Going ahead to step 11:
3680 divided by 987 is 3 with a remainder of 719.
The number 3 becomes the next digit in our result. 
Result so far: 93632.363
If we subtract 2961 from 3680, we get 719.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7190, and continue the process.

Let's proceed to step 12:
If we divide 7190 by 987, we get 7 and a remainder of 281.
Write down 7 as next digit of the result. 
Result so far: 93632.3637
Subtracting 6909 from 7190 leaves us with 281.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2810, and continue the process.

Moving on to step 13:
If we divide 2810 by 987, we get 2 and a remainder of 836.
Put 2 as the next digit of the answer. 
Result so far: 93632.36372
The remainder is 836 after subtracting 1974 from 2810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8360, and continue the process.

Step 14:
987 goes into 8360 8 times with a remainder of 464.
The number 8 becomes the next digit in our result. 
Result so far: 93632.363728
If we subtract 7896 from 8360, we get 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Moving on to step 15:
When dividing 4640 by 987, we get 4 with a remainder of 692.
Put 4 as the next digit of the answer. 
Result so far: 93632.3637284
The remainder is 692 after subtracting 3948 from 4640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6920, and continue the process.

Step 16:
When dividing 6920 by 987, we get 7 with a remainder of 11.
Use 7 as the next digit of our solution. 
Result so far: 93632.36372847
Deduct 6909 from 6920 and we're left 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.

The final result is 93632.36372847 with a remainder of 1.1e-08.
