We look at the division of 561780 by 59 
The aim is to understand the frequency of 59 in 561780.

Step 1:
The number 59 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 59

Going ahead to step 2:
If we divide 56 by 59, we get 0 and a remainder of 56.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 56 and we're left with 56.
Bring next digit (1) of the dividend behind the 56 and repeat the process: 561 / 59

Going ahead to step 3:
If we divide 561 by 59, we get 9 and a remainder of 30.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we take 531 away from 561, we end up with 30.
Bring next digit (7) of the dividend behind the 30 and repeat the process: 307 / 59

Let's proceed to step 4:
59 can be fit into 307 5 times, resulting in a remainder of 12.
Use 5 as the next digit of our solution. 
Result so far: 95.0
If we take 295 away from 307, we end up with 12.
Bring next digit (8) of the dividend behind the 12 and repeat the process: 128 / 59

Going ahead to step 5:
If we divide 128 by 59, we get 2 and a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 952.0
If we take 118 away from 128, we end up with 10.
Bring next digit (0) of the dividend behind the 10 and repeat the process: 100 / 59

Let's proceed to step 6:
When dividing 100 by 59, we get 1 with a remainder of 41.
Write down 1 as next digit of the result. 
Result so far: 9521.0
If we take 59 away from 100, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 7:
If we divide 410 by 59, we get 6 and a remainder of 56.
The number 6 becomes the next digit in our result. 
Result so far: 9521.6
If we subtract 354 from 410, we 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.

Let's proceed to step 8:
When dividing 560 by 59, we get 9 with a remainder of 29.
The next digit of our result is 9. 
Result so far: 9521.69
If we subtract 531 from 560, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 9:
If we divide 290 by 59, we get 4 and a remainder of 54.
Write down 4 as next digit of the result. 
Result so far: 9521.694
If we subtract 236 from 290, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 10:
59 can be fit into 540 9 times, resulting in a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 9521.6949
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.

Moving on to step 11:
59 can be fit into 90 1 times, resulting in a remainder of 31.
The next digit of our result is 1. 
Result so far: 9521.69491
Subtract 59 from 90 to 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.

Advancing to step 12:
If we divide 310 by 59, we get 5 and a remainder of 15.
The next digit of our result is 5. 
Result so far: 9521.694915
Subtracting 295 from 310 leaves us 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.

Advancing to step 13:
The number 59 fits into 150 2 times, leaving a remainder of 32.
The next digit of our result is 2. 
Result so far: 9521.6949152
Deduct 118 from 150 and we're left 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.

Going ahead to step 14:
320 divided by 59 is 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 9521.69491525
Subtract 295 from 320 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

After the division, we end up with 9521.69491525 and a remainder of 2.5e-08.
