86001 divided by 19 
The aim is to understand the frequency of 19 in 86001.

Let's proceed to step 1:
When dividing 8 by 19, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 19

Moving on to step 2:
When dividing 86 by 19, we get 4 with a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 76 away from 86, we end up with 10.
Fetch the next digit (0) from the dividend, attach it to 10 and continue: 100 / 19

Moving on to step 3:
If we divide 100 by 19, we get 5 and a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 45.0
Subtracting 95 from 100 leaves us with 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 19

On to step 4:
When dividing 50 by 19, we get 2 with a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 452.0
If we subtract 38 from 50, we get 12.
Include the next digit (1) from the dividend after 12, then repeat: 121 / 19

Step 5:
19 can be fit into 121 6 times, resulting in a remainder of 7.
Record the quotient 6 as the next digit in the result. 
Result so far: 4526.0
If we subtract 114 from 121, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 6:
19 goes into 70 3 times with a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 4526.3
If we take 57 away from 70, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 7:
If we divide 130 by 19, we get 6 and a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 4526.36
If we subtract 114 from 130, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 8:
If we divide 160 by 19, we get 8 and a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 4526.368
Subtracting 152 from 160 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.

Advancing to step 9:
When dividing 80 by 19, we get 4 with a remainder of 4.
The next digit of our result is 4. 
Result so far: 4526.3684
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.

Moving on to step 10:
19 can be fit into 40 2 times, resulting in a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 4526.36842
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.

On to step 11:
20 divided by 19 is 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 4526.368421
Subtracting 19 from 20 leaves us with 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 12:
The number 19 fits into 10 0 times, leaving a remainder of 10.
The next digit of our result is 0. 
Result so far: 4526.368421
If we take 0 away from 10, we end up 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.

Advancing to step 13:
If we divide 100 by 19, we get 5 and a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 4526.36842105
Deduct 95 from 100 and we're left 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.

The quotient of the division is 4526.36842105, and the remainder is 5e-09.
