We're dividing 57160 by 19 
The aim is to understand the frequency of 19 in 57160.

Advancing to step 1:
19 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 19

Moving on to step 2:
19 goes into 57 3 times with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 57 from 57, we get 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 19

Step 3:
19 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
If we subtract 0 from 1, we get 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 19

On to step 4:
If we divide 16 by 19, we get 0 and a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 300.0
Deduct 0 from 16 and we're left with 16.
Grab the next digit (0) from the dividend, add it to 16, then carry on: 160 / 19

Going ahead to step 5:
If we divide 160 by 19, we get 8 and a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 3008.0
Deduct 152 from 160 and we're left 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.

Moving on to step 6:
19 can be fit into 80 4 times, resulting in a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 3008.4
Deduct 76 from 80 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.

Going ahead to step 7:
If we divide 40 by 19, we get 2 and a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 3008.42
If we subtract 38 from 40, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 8:
If we divide 20 by 19, we get 1 and a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 3008.421
If we subtract 19 from 20, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 9:
19 goes into 10 0 times with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 3008.421
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 10:
19 goes into 100 5 times with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 3008.42105
If we take 95 away from 100, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 11:
50 divided by 19 is 2 with a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 3008.421052
Deduct 38 from 50 and we're left 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.

On to step 12:
The number 19 fits into 120 6 times, leaving a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 3008.4210526
If we take 114 away from 120, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 13:
If we divide 60 by 19, we get 3 and a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 3008.42105263
If we take 57 away from 60, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The final outcome is 3008.42105263, with a leftover of 3e-09.
