We look at the division of 89784958 by 668 
The aim is to understand the frequency of 668 in 89784958.

Advancing to step 1:
The number 668 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 668

Going ahead to step 2:
668 can be fit into 89 0 times, resulting in a remainder of 89.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 89 leaves us with 89.
Grab the next digit (7) from the dividend, add it to 89, then carry on: 897 / 668

On to step 3:
The number 668 fits into 897 1 times, leaving a remainder of 229.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 668 from 897 to get 229.
Bring next digit (8) of the dividend behind the 229 and repeat the process: 2298 / 668

Moving on to step 4:
668 goes into 2298 3 times with a remainder of 294.
The next digit of our result is 3. 
Result so far: 13.0
Subtracting 2004 from 2298 leaves us with 294.
Grab the next digit (4) from the dividend, add it to 294, then carry on: 2944 / 668

On to step 5:
If we divide 2944 by 668, we get 4 and a remainder of 272.
Put 4 as the next digit of the answer. 
Result so far: 134.0
Subtracting 2672 from 2944 leaves us with 272.
Bring next digit (9) of the dividend behind the 272 and repeat the process: 2729 / 668

Advancing to step 6:
When dividing 2729 by 668, we get 4 with a remainder of 57.
Record the quotient 4 as the next digit in the result. 
Result so far: 1344.0
If we take 2672 away from 2729, we end up with 57.
Grab the next digit (5) from the dividend, add it to 57, then carry on: 575 / 668

Moving on to step 7:
668 goes into 575 0 times with a remainder of 575.
The number 0 becomes the next digit in our result. 
Result so far: 13440.0
Deduct 0 from 575 and we're left with 575.
Grab the next digit (8) from the dividend, add it to 575, then carry on: 5758 / 668

On to step 8:
668 goes into 5758 8 times with a remainder of 414.
Record the quotient 8 as the next digit in the result. 
Result so far: 134408.0
If we take 5344 away from 5758, we end up with 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

Step 9:
4140 divided by 668 is 6 with a remainder of 132.
The next digit of our result is 6. 
Result so far: 134408.6
Subtracting 4008 from 4140 leaves us with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Advancing to step 10:
668 goes into 1320 1 times with a remainder of 652.
Use 1 as the next digit of our solution. 
Result so far: 134408.61
If we subtract 668 from 1320, we get 652.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6520, and continue the process.

Moving on to step 11:
If we divide 6520 by 668, we get 9 and a remainder of 508.
The number 9 becomes the next digit in our result. 
Result so far: 134408.619
If we subtract 6012 from 6520, we get 508.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

Moving on to step 12:
The number 668 fits into 5080 7 times, leaving a remainder of 404.
Put 7 as the next digit of the answer. 
Result so far: 134408.6197
If we take 4676 away from 5080, we end up with 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

On to step 13:
When dividing 4040 by 668, we get 6 with a remainder of 32.
The next digit of our result is 6. 
Result so far: 134408.61976
If we subtract 4008 from 4040, 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.

Moving on to step 14:
The number 668 fits into 320 0 times, leaving a remainder of 320.
Put 0 as the next digit of the answer. 
Result so far: 134408.61976
The remainder is 320 after subtracting 0 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Moving on to step 15:
668 can be fit into 3200 4 times, resulting in a remainder of 528.
The number 4 becomes the next digit in our result. 
Result so far: 134408.6197604
Deduct 2672 from 3200 and we're left with 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

On to step 16:
668 goes into 5280 7 times with a remainder of 604.
The next digit of our result is 7. 
Result so far: 134408.61976047
Subtract 4676 from 5280 to get 604.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

Our division results in 134408.61976047 with a remaining 6.04e-07.
