We're dividing 901539 by 19 
The aim is to understand the frequency of 19 in 901539.

Advancing to step 1:
19 goes into 9 0 times with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 19

Step 2:
90 divided by 19 is 4 with a remainder of 14.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 76 from 90 and we're left with 14.
Bring next digit (1) of the dividend behind the 14 and repeat the process: 141 / 19

Going ahead to step 3:
141 divided by 19 is 7 with a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 47.0
If we take 133 away from 141, we end up with 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 19

Let's proceed to step 4:
85 divided by 19 is 4 with a remainder of 9.
The next digit of our result is 4. 
Result so far: 474.0
The remainder is 9 after subtracting 76 from 85.
Take the next digit (3) from the dividend and append it to 9, then repeat: 93 / 19

Step 5:
When dividing 93 by 19, we get 4 with a remainder of 17.
Write down 4 as next digit of the result. 
Result so far: 4744.0
Subtract 76 from 93 to get 17.
Append the next digit (9) from the dividend to 17 and continue with: 179 / 19

On to step 6:
179 divided by 19 is 9 with a remainder of 8.
The number 9 becomes the next digit in our result. 
Result so far: 47449.0
Subtracting 171 from 179 leaves us 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.

Let's proceed to step 7:
When dividing 80 by 19, we get 4 with a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 47449.4
If we take 76 away from 80, we end up 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 19 is 2 with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 47449.42
If we take 38 away from 40, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 9:
19 goes into 20 1 times with a remainder of 1.
The next digit of our result is 1. 
Result so far: 47449.421
Subtract 19 from 20 to 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.

Step 10:
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: 47449.421
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 11:
The number 19 fits into 100 5 times, leaving a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 47449.42105
Subtract 95 from 100 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 12:
50 divided by 19 is 2 with a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 47449.421052
Subtracting 38 from 50 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.

Advancing to step 13:
19 can be fit into 120 6 times, resulting in a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 47449.4210526
Subtract 114 from 120 to 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.

Advancing to step 14:
If we divide 60 by 19, we get 3 and a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 47449.42105263
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 result is 47449.42105263 with a remainder of 3e-09.
