We divide 686315 by 89
The aim is to understand the frequency of 89 in 686315.

Step 1:
If we divide 6 by 89, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 89

On to step 2:
When dividing 68 by 89, we get 0 with a remainder of 68.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 68, we get 68.
Take the next digit (6) from the dividend and append it to 68, then repeat: 686 / 89

Going ahead to step 3:
The number 89 fits into 686 7 times, leaving a remainder of 63.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtracting 623 from 686 leaves us with 63.
Take the next digit (3) from the dividend and append it to 63, then repeat: 633 / 89

On to step 4:
If we divide 633 by 89, we get 7 and a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 77.0
If we take 623 away from 633, we end up with 10.
Bring next digit (1) of the dividend behind the 10 and repeat the process: 101 / 89

Step 5:
89 goes into 101 1 times with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 771.0
If we take 89 away from 101, we end up with 12.
Grab the next digit (5) from the dividend, add it to 12, then carry on: 125 / 89

Let's proceed to step 6:
If we divide 125 by 89, we get 1 and a remainder of 36.
Write down 1 as next digit of the result. 
Result so far: 7711.0
If we take 89 away from 125, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 7:
The number 89 fits into 360 4 times, leaving a remainder of 4.
The next digit of our result is 4. 
Result so far: 7711.4
The remainder is 4 after subtracting 356 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 8:
The number 89 fits into 40 0 times, leaving a remainder of 40.
The next digit of our result is 0. 
Result so far: 7711.4
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
400 divided by 89 is 4 with a remainder of 44.
The next digit of our result is 4. 
Result so far: 7711.404
Subtract 356 from 400 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 10:
The number 89 fits into 440 4 times, leaving a remainder of 84.
Record the quotient 4 as the next digit in the result. 
Result so far: 7711.4044
If we take 356 away from 440, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

The quotient of the division is 7711.4044, and the remainder is 0.00084.
