Let's divide 642670 by 89
The aim is to understand the frequency of 89 in 642670.

Step 1:
89 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 89

Step 2:
64 divided by 89 is 0 with a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Bring next digit (2) of the dividend behind the 64 and repeat the process: 642 / 89

Moving on to step 3:
When dividing 642 by 89, we get 7 with a remainder of 19.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 623 from 642, we get 19.
Grab the next digit (6) from the dividend, add it to 19, then carry on: 196 / 89

Moving on to step 4:
The number 89 fits into 196 2 times, leaving a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 72.0
Deduct 178 from 196 and we're left with 18.
Bring next digit (7) of the dividend behind the 18 and repeat the process: 187 / 89

On to step 5:
89 can be fit into 187 2 times, resulting in a remainder of 9.
The number 2 becomes the next digit in our result. 
Result so far: 722.0
Deduct 178 from 187 and we're left with 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 89

Going ahead to step 6:
90 divided by 89 is 1 with a remainder of 1.
The next digit of our result is 1. 
Result so far: 7221.0
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.

Going ahead to step 7:
89 goes into 10 0 times with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 7221.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
89 goes into 100 1 times with a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 7221.01
Deduct 89 from 100 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 9:
The number 89 fits into 110 1 times, leaving a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 7221.011
Subtracting 89 from 110 leaves us 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.

In conclusion, the division gives 7221.011 with a balance of 0.0021.
