We look at the division of 57954594 by 987 
The aim is to understand the frequency of 987 in 57954594.

Moving on to step 1:
When dividing 5 by 987, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 987

Advancing to step 2:
When dividing 57 by 987, we get 0 with a remainder of 57.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 57 to get 57.
Append the next digit (9) from the dividend to 57 and continue with: 579 / 987

Moving on to step 3:
If we divide 579 by 987, we get 0 and a remainder of 579.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 579, we end up with 579.
Take the next digit (5) from the dividend and append it to 579, then repeat: 5795 / 987

Step 4:
The number 987 fits into 5795 5 times, leaving a remainder of 860.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtract 4935 from 5795 to get 860.
Append the next digit (4) from the dividend to 860 and continue with: 8604 / 987

Advancing to step 5:
The number 987 fits into 8604 8 times, leaving a remainder of 708.
The number 8 becomes the next digit in our result. 
Result so far: 58.0
If we take 7896 away from 8604, we end up with 708.
Grab the next digit (5) from the dividend, add it to 708, then carry on: 7085 / 987

Going ahead to step 6:
When dividing 7085 by 987, we get 7 with a remainder of 176.
Record the quotient 7 as the next digit in the result. 
Result so far: 587.0
If we take 6909 away from 7085, we end up with 176.
Grab the next digit (9) from the dividend, add it to 176, then carry on: 1769 / 987

Step 7:
987 goes into 1769 1 times with a remainder of 782.
Write down 1 as next digit of the result. 
Result so far: 5871.0
Subtract 987 from 1769 to get 782.
Take the next digit (4) from the dividend and append it to 782, then repeat: 7824 / 987

Advancing to step 8:
When dividing 7824 by 987, we get 7 with a remainder of 915.
The number 7 becomes the next digit in our result. 
Result so far: 58717.0
If we take 6909 away from 7824, we end up with 915.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9150, and continue the process.

Advancing to step 9:
If we divide 9150 by 987, we get 9 and a remainder of 267.
The next digit of our result is 9. 
Result so far: 58717.9
Subtract 8883 from 9150 to get 267.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

Advancing to step 10:
987 goes into 2670 2 times with a remainder of 696.
Put 2 as the next digit of the answer. 
Result so far: 58717.92
If we take 1974 away from 2670, we end up with 696.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6960, and continue the process.

Going ahead to step 11:
When dividing 6960 by 987, we get 7 with a remainder of 51.
The number 7 becomes the next digit in our result. 
Result so far: 58717.927
Deduct 6909 from 6960 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Advancing to step 12:
510 divided by 987 is 0 with a remainder of 510.
Put 0 as the next digit of the answer. 
Result so far: 58717.927
Deduct 0 from 510 and we're left with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

On to step 13:
If we divide 5100 by 987, we get 5 and a remainder of 165.
Record the quotient 5 as the next digit in the result. 
Result so far: 58717.92705
Subtracting 4935 from 5100 leaves us with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Step 14:
987 can be fit into 1650 1 times, resulting in a remainder of 663.
Put 1 as the next digit of the answer. 
Result so far: 58717.927051
Deduct 987 from 1650 and we're left with 663.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6630, and continue the process.

Advancing to step 15:
When dividing 6630 by 987, we get 6 with a remainder of 708.
Put 6 as the next digit of the answer. 
Result so far: 58717.9270516
If we take 5922 away from 6630, we end up with 708.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7080, and continue the process.

Step 16:
7080 divided by 987 is 7 with a remainder of 171.
The next digit of our result is 7. 
Result so far: 58717.92705167
Subtracting 6909 from 7080 leaves us with 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

After the division, we end up with 58717.92705167 and a remainder of 1.71e-07.
