Let's divide 561916 by 58
The aim is to understand the frequency of 58 in 561916.

On to step 1:
If we divide 5 by 58, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (6) of the dividend behind the 5 and repeat the process: 56 / 58

Moving on to step 2:
When dividing 56 by 58, we get 0 with a remainder of 56.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 56 leaves us with 56.
Bring next digit (1) of the dividend behind the 56 and repeat the process: 561 / 58

On to step 3:
The number 58 fits into 561 9 times, leaving a remainder of 39.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtracting 522 from 561 leaves us with 39.
Fetch the next digit (9) from the dividend, attach it to 39 and continue: 399 / 58

Let's proceed to step 4:
When dividing 399 by 58, we get 6 with a remainder of 51.
Put 6 as the next digit of the answer. 
Result so far: 96.0
Deduct 348 from 399 and we're left with 51.
Append the next digit (1) from the dividend to 51 and continue with: 511 / 58

Step 5:
The number 58 fits into 511 8 times, leaving a remainder of 47.
The number 8 becomes the next digit in our result. 
Result so far: 968.0
If we take 464 away from 511, we end up with 47.
Append the next digit (6) from the dividend to 47 and continue with: 476 / 58

On to step 6:
58 goes into 476 8 times with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 9688.0
Subtracting 464 from 476 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 7:
When dividing 120 by 58, we get 2 with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 9688.2
Deduct 116 from 120 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 8:
40 divided by 58 is 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 9688.2
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 9:
The number 58 fits into 400 6 times, leaving a remainder of 52.
Put 6 as the next digit of the answer. 
Result so far: 9688.206
Subtracting 348 from 400 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 10:
When dividing 520 by 58, we get 8 with a remainder of 56.
Write down 8 as next digit of the result. 
Result so far: 9688.2068
Subtract 464 from 520 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.

Advancing to step 11:
If we divide 560 by 58, we get 9 and a remainder of 38.
Write down 9 as next digit of the result. 
Result so far: 9688.20689
If we subtract 522 from 560, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 12:
380 divided by 58 is 6 with a remainder of 32.
The next digit of our result is 6. 
Result so far: 9688.206896
If we take 348 away from 380, 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.

On to step 13:
If we divide 320 by 58, we get 5 and a remainder of 30.
The next digit of our result is 5. 
Result so far: 9688.2068965
Subtract 290 from 320 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 14:
58 can be fit into 300 5 times, resulting in a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 9688.20689655
Deduct 290 from 300 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 9688.20689655, with a leftover of 1e-08.
