404938 divided by 89 
The aim is to understand the frequency of 89 in 404938.

On to step 1:
89 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 89

Step 2:
89 goes into 40 0 times with a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Append the next digit (4) from the dividend to 40 and continue with: 404 / 89

On to step 3:
89 goes into 404 4 times with a remainder of 48.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 48 after subtracting 356 from 404.
Grab the next digit (9) from the dividend, add it to 48, then carry on: 489 / 89

Step 4:
If we divide 489 by 89, we get 5 and a remainder of 44.
The number 5 becomes the next digit in our result. 
Result so far: 45.0
Subtract 445 from 489 to get 44.
Fetch the next digit (3) from the dividend, attach it to 44 and continue: 443 / 89

Advancing to step 5:
89 can be fit into 443 4 times, resulting in a remainder of 87.
Use 4 as the next digit of our solution. 
Result so far: 454.0
If we subtract 356 from 443, we get 87.
Append the next digit (8) from the dividend to 87 and continue with: 878 / 89

Moving on to step 6:
89 can be fit into 878 9 times, resulting in a remainder of 77.
Use 9 as the next digit of our solution. 
Result so far: 4549.0
Subtracting 801 from 878 leaves us with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

On to step 7:
89 can be fit into 770 8 times, resulting in a remainder of 58.
The number 8 becomes the next digit in our result. 
Result so far: 4549.8
The remainder is 58 after subtracting 712 from 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 8:
89 goes into 580 6 times with a remainder of 46.
Put 6 as the next digit of the answer. 
Result so far: 4549.86
The remainder is 46 after subtracting 534 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 9:
460 divided by 89 is 5 with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 4549.865
Subtracting 445 from 460 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 10:
150 divided by 89 is 1 with a remainder of 61.
The next digit of our result is 1. 
Result so far: 4549.8651
Subtracting 89 from 150 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 11:
89 can be fit into 610 6 times, resulting in a remainder of 76.
The next digit of our result is 6. 
Result so far: 4549.86516
Deduct 534 from 610 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 12:
89 can be fit into 760 8 times, resulting in a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 4549.865168
Deduct 712 from 760 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 13:
If we divide 480 by 89, we get 5 and a remainder of 35.
The next digit of our result is 5. 
Result so far: 4549.8651685
If we take 445 away from 480, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 14:
If we divide 350 by 89, we get 3 and a remainder of 83.
Write down 3 as next digit of the result. 
Result so far: 4549.86516853
Subtract 267 from 350 to get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

After the division, we end up with 4549.86516853 and a remainder of 8.3e-08.
