We divide 646117 by 89
The aim is to understand the frequency of 89 in 646117.

On to step 1:
When dividing 6 by 89, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 89

Advancing to step 2:
89 goes into 64 0 times with a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Grab the next digit (6) from the dividend, add it to 64, then carry on: 646 / 89

Advancing to step 3:
If we divide 646 by 89, we get 7 and a remainder of 23.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 623 from 646 and we're left with 23.
Fetch the next digit (1) from the dividend, attach it to 23 and continue: 231 / 89

Step 4:
89 can be fit into 231 2 times, resulting in a remainder of 53.
Use 2 as the next digit of our solution. 
Result so far: 72.0
Subtract 178 from 231 to get 53.
Include the next digit (1) from the dividend after 53, then repeat: 531 / 89

Step 5:
531 divided by 89 is 5 with a remainder of 86.
The number 5 becomes the next digit in our result. 
Result so far: 725.0
Subtract 445 from 531 to get 86.
Grab the next digit (7) from the dividend, add it to 86, then carry on: 867 / 89

Let's proceed to step 6:
The number 89 fits into 867 9 times, leaving a remainder of 66.
Put 9 as the next digit of the answer. 
Result so far: 7259.0
Subtract 801 from 867 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 7:
89 goes into 660 7 times with a remainder of 37.
The next digit of our result is 7. 
Result so far: 7259.7
Deduct 623 from 660 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 8:
89 goes into 370 4 times with a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 7259.74
Subtracting 356 from 370 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 9:
89 goes into 140 1 times with a remainder of 51.
Write down 1 as next digit of the result. 
Result so far: 7259.741
Subtracting 89 from 140 leaves us 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.

Moving on to step 10:
89 can be fit into 510 5 times, resulting in a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 7259.7415
If we subtract 445 from 510, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 11:
The number 89 fits into 650 7 times, leaving a remainder of 27.
The next digit of our result is 7. 
Result so far: 7259.74157
The remainder is 27 after subtracting 623 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 12:
If we divide 270 by 89, we get 3 and a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 7259.741573
Deduct 267 from 270 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 13:
The number 89 fits into 30 0 times, leaving a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 7259.741573
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.

Going ahead to step 14:
89 goes into 300 3 times with a remainder of 33.
The number 3 becomes the next digit in our result. 
Result so far: 7259.74157303
Subtract 267 from 300 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

The quotient of the division is 7259.74157303, and the remainder is 3.3e-08.
