83861 ÷ 19 
We want to figure out the number of times 83861 can be divided by 19.

Going ahead to step 1:
19 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 19

Going ahead to step 2:
The number 19 fits into 83 4 times, leaving a remainder of 7.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 76 from 83, we get 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 19

Let's proceed to step 3:
If we divide 78 by 19, we get 4 and a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 44.0
The remainder is 2 after subtracting 76 from 78.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 19

Going ahead to step 4:
26 divided by 19 is 1 with a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 441.0
If we subtract 19 from 26, we get 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 19

Let's proceed to step 5:
71 divided by 19 is 3 with a remainder of 14.
The number 3 becomes the next digit in our result. 
Result so far: 4413.0
If we take 57 away from 71, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 6:
When dividing 140 by 19, we get 7 with a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 4413.7
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.

Moving on to step 7:
When dividing 70 by 19, we get 3 with a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 4413.73
Subtracting 57 from 70 leaves us 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.

Step 8:
When dividing 130 by 19, we get 6 with a remainder of 16.
The next digit of our result is 6. 
Result so far: 4413.736
Subtracting 114 from 130 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 9:
19 can be fit into 160 8 times, resulting in a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 4413.7368
If we subtract 152 from 160, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 10:
When dividing 80 by 19, we get 4 with a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 4413.73684
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.

On to step 11:
The number 19 fits into 40 2 times, leaving a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 4413.736842
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.

Let's proceed to step 12:
The number 19 fits into 20 1 times, leaving a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 4413.7368421
The remainder is 1 after subtracting 19 from 20.
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 13:
10 divided by 19 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 4413.7368421
Deduct 0 from 10 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 4413.7368421, with a leftover of 1e-08.
