We look at the division of 725638 by 59 
The aim is to understand the frequency of 59 in 725638.

On to step 1:
59 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 59

On to step 2:
59 goes into 72 1 times with a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 59 from 72 to get 13.
Bring next digit (5) of the dividend behind the 13 and repeat the process: 135 / 59

Step 3:
135 divided by 59 is 2 with a remainder of 17.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtract 118 from 135 to get 17.
Include the next digit (6) from the dividend after 17, then repeat: 176 / 59

Going ahead to step 4:
If we divide 176 by 59, we get 2 and a remainder of 58.
Write down 2 as next digit of the result. 
Result so far: 122.0
The remainder is 58 after subtracting 118 from 176.
Fetch the next digit (3) from the dividend, attach it to 58 and continue: 583 / 59

Step 5:
The number 59 fits into 583 9 times, leaving a remainder of 52.
The next digit of our result is 9. 
Result so far: 1229.0
If we take 531 away from 583, we end up with 52.
Append the next digit (8) from the dividend to 52 and continue with: 528 / 59

Going ahead to step 6:
When dividing 528 by 59, we get 8 with a remainder of 56.
Put 8 as the next digit of the answer. 
Result so far: 12298.0
Subtract 472 from 528 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 7:
The number 59 fits into 560 9 times, leaving a remainder of 29.
The number 9 becomes the next digit in our result. 
Result so far: 12298.9
If we take 531 away from 560, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 8:
59 can be fit into 290 4 times, resulting in a remainder of 54.
The next digit of our result is 4. 
Result so far: 12298.94
If we take 236 away from 290, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 9:
If we divide 540 by 59, we get 9 and a remainder of 9.
The next digit of our result is 9. 
Result so far: 12298.949
If we take 531 away from 540, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 10:
59 goes into 90 1 times with a remainder of 31.
Use 1 as the next digit of our solution. 
Result so far: 12298.9491
If we subtract 59 from 90, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 11:
59 can be fit into 310 5 times, resulting in a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 12298.94915
Deduct 295 from 310 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 12:
If we divide 150 by 59, we get 2 and a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 12298.949152
If we take 118 away from 150, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 13:
320 divided by 59 is 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 12298.9491525
If we take 295 away from 320, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 14:
59 can be fit into 250 4 times, resulting in a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 12298.94915254
If we take 236 away from 250, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Our division results in 12298.94915254 with a remaining 1.4e-08.
