Let's divide 721337 by 89
The aim is to understand the frequency of 89 in 721337.

Step 1:
When dividing 7 by 89, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 89

Going ahead to step 2:
89 goes into 72 0 times with a remainder of 72.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 72 after subtracting 0 from 72.
Fetch the next digit (1) from the dividend, attach it to 72 and continue: 721 / 89

Step 3:
89 can be fit into 721 8 times, resulting in a remainder of 9.
Write down 8 as next digit of the result. 
Result so far: 8.0
Deduct 712 from 721 and we're left with 9.
Bring next digit (3) of the dividend behind the 9 and repeat the process: 93 / 89

Step 4:
The number 89 fits into 93 1 times, leaving a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 81.0
If we take 89 away from 93, we end up with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 89

Advancing to step 5:
The number 89 fits into 43 0 times, leaving a remainder of 43.
Write down 0 as next digit of the result. 
Result so far: 810.0
Deduct 0 from 43 and we're left with 43.
Grab the next digit (7) from the dividend, add it to 43, then carry on: 437 / 89

Let's proceed to step 6:
When dividing 437 by 89, we get 4 with a remainder of 81.
The next digit of our result is 4. 
Result so far: 8104.0
Deduct 356 from 437 and we're left with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

On to step 7:
89 can be fit into 810 9 times, resulting in a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 8104.9
If we subtract 801 from 810, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 8:
The number 89 fits into 90 1 times, leaving a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 8104.91
Subtracting 89 from 90 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 9:
89 goes into 10 0 times with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 8104.91
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 10:
89 goes into 100 1 times with a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 8104.9101
Subtract 89 from 100 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 11:
89 goes into 110 1 times with a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 8104.91011
If we take 89 away from 110, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

The quotient of the division is 8104.91011, and the remainder is 2.1e-05.
