We divide 720639 by 59
The aim is to understand the frequency of 59 in 720639.

Step 1:
If we divide 7 by 59, we get 0 and a remainder of 7.
The next digit of our result is 0. 
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 / 59

Moving on to step 2:
59 can be fit into 72 1 times, resulting in a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 59 from 72, we get 13.
Append the next digit (0) from the dividend to 13 and continue with: 130 / 59

Advancing to step 3:
If we divide 130 by 59, we get 2 and a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we subtract 118 from 130, we get 12.
Grab the next digit (6) from the dividend, add it to 12, then carry on: 126 / 59

On to step 4:
126 divided by 59 is 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 122.0
If we subtract 118 from 126, we get 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 59

Advancing to step 5:
59 goes into 83 1 times with a remainder of 24.
Record the quotient 1 as the next digit in the result. 
Result so far: 1221.0
Deduct 59 from 83 and we're left with 24.
Append the next digit (9) from the dividend to 24 and continue with: 249 / 59

Step 6:
When dividing 249 by 59, we get 4 with a remainder of 13.
The number 4 becomes the next digit in our result. 
Result so far: 12214.0
The remainder is 13 after subtracting 236 from 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 7:
59 goes into 130 2 times with a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 12214.2
Subtract 118 from 130 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 8:
If we divide 120 by 59, we get 2 and a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 12214.22
Deduct 118 from 120 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final result is 12214.22 with a remainder of 0.002.
