We're dividing 70781 by 19 
The aim is to understand the frequency of 19 in 70781.

Moving on to step 1:
The number 19 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 19

Moving on to step 2:
The number 19 fits into 70 3 times, leaving a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 57 from 70 and we're left with 13.
Take the next digit (7) from the dividend and append it to 13, then repeat: 137 / 19

On to step 3:
The number 19 fits into 137 7 times, leaving a remainder of 4.
The next digit of our result is 7. 
Result so far: 37.0
Subtracting 133 from 137 leaves us with 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 19

Advancing to step 4:
19 can be fit into 48 2 times, resulting in a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 372.0
Subtract 38 from 48 to get 10.
Append the next digit (1) from the dividend to 10 and continue with: 101 / 19

Going ahead to step 5:
19 can be fit into 101 5 times, resulting in a remainder of 6.
Write down 5 as next digit of the result. 
Result so far: 3725.0
If we subtract 95 from 101, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 6:
19 can be fit into 60 3 times, resulting in a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 3725.3
The remainder is 3 after subtracting 57 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
If we divide 30 by 19, we get 1 and a remainder of 11.
The next digit of our result is 1. 
Result so far: 3725.31
Subtracting 19 from 30 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 8:
19 goes into 110 5 times with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 3725.315
If we take 95 away from 110, we end up 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.

Going ahead to step 9:
150 divided by 19 is 7 with a remainder of 17.
Use 7 as the next digit of our solution. 
Result so far: 3725.3157
Subtracting 133 from 150 leaves us with 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 10:
19 goes into 170 8 times with a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 3725.31578
Subtracting 152 from 170 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 11:
180 divided by 19 is 9 with a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 3725.315789
Subtracting 171 from 180 leaves us 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 12:
90 divided by 19 is 4 with a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 3725.3157894
Subtract 76 from 90 to 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.

Advancing to step 13:
If we divide 140 by 19, we get 7 and a remainder of 7.
The next digit of our result is 7. 
Result so far: 3725.31578947
If we take 133 away from 140, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

The final outcome is 3725.31578947, with a leftover of 7e-09.
