669396 divided by 89 
The aim is to understand the frequency of 89 in 669396.

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
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 89

Advancing to step 2:
When dividing 66 by 89, we get 0 with a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Fetch the next digit (9) from the dividend, attach it to 66 and continue: 669 / 89

On to step 3:
89 goes into 669 7 times with a remainder of 46.
The next digit of our result is 7. 
Result so far: 7.0
Deduct 623 from 669 and we're left with 46.
Include the next digit (3) from the dividend after 46, then repeat: 463 / 89

On to step 4:
If we divide 463 by 89, we get 5 and a remainder of 18.
The number 5 becomes the next digit in our result. 
Result so far: 75.0
Subtract 445 from 463 to get 18.
Grab the next digit (9) from the dividend, add it to 18, then carry on: 189 / 89

Let's proceed to step 5:
89 goes into 189 2 times with a remainder of 11.
Record the quotient 2 as the next digit in the result. 
Result so far: 752.0
Deduct 178 from 189 and we're left with 11.
Grab the next digit (6) from the dividend, add it to 11, then carry on: 116 / 89

Advancing to step 6:
116 divided by 89 is 1 with a remainder of 27.
Record the quotient 1 as the next digit in the result. 
Result so far: 7521.0
Deduct 89 from 116 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 7:
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: 7521.3
The remainder is 3 after subtracting 267 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 8:
When dividing 30 by 89, we get 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 7521.3
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 9:
89 goes into 300 3 times with a remainder of 33.
Use 3 as the next digit of our solution. 
Result so far: 7521.303
If we take 267 away from 300, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 10:
330 divided by 89 is 3 with a remainder of 63.
Write down 3 as next digit of the result. 
Result so far: 7521.3033
Deduct 267 from 330 and we're left with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

The quotient of the division is 7521.3033, and the remainder is 0.00063.
