598521 ÷ 59 
The aim is to understand the frequency of 59 in 598521.

Advancing to step 1:
When dividing 5 by 59, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Bring next digit (9) of the dividend behind the 5 and repeat the process: 59 / 59

Moving on to step 2:
The number 59 fits into 59 1 times, leaving a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 0 after subtracting 59 from 59.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 59

Going ahead to step 3:
59 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 59

Let's proceed to step 4:
If we divide 85 by 59, we get 1 and a remainder of 26.
Write down 1 as next digit of the result. 
Result so far: 101.0
The remainder is 26 after subtracting 59 from 85.
Append the next digit (2) from the dividend to 26 and continue with: 262 / 59

Going ahead to step 5:
262 divided by 59 is 4 with a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 1014.0
Deduct 236 from 262 and we're left with 26.
Take the next digit (1) from the dividend and append it to 26, then repeat: 261 / 59

Let's proceed to step 6:
The number 59 fits into 261 4 times, leaving a remainder of 25.
Record the quotient 4 as the next digit in the result. 
Result so far: 10144.0
If we take 236 away from 261, 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.

Step 7:
When dividing 250 by 59, we get 4 with a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 10144.4
If we subtract 236 from 250, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 8:
The number 59 fits into 140 2 times, leaving a remainder of 22.
Use 2 as the next digit of our solution. 
Result so far: 10144.42
If we take 118 away from 140, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 9:
220 divided by 59 is 3 with a remainder of 43.
Put 3 as the next digit of the answer. 
Result so far: 10144.423
Subtract 177 from 220 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 10:
59 can be fit into 430 7 times, resulting in a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 10144.4237
If we subtract 413 from 430, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 11:
The number 59 fits into 170 2 times, leaving a remainder of 52.
Record the quotient 2 as the next digit in the result. 
Result so far: 10144.42372
The remainder is 52 after subtracting 118 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 12:
59 can be fit into 520 8 times, resulting in a remainder of 48.
Use 8 as the next digit of our solution. 
Result so far: 10144.423728
If we take 472 away from 520, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 13:
59 goes into 480 8 times with a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 10144.4237288
If we take 472 away from 480, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 10144.4237288, with a leftover of 8e-08.
