We're dividing 78602 by 19 
We're looking to find how many times 19 goes into 78602.

On to step 1:
19 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 19

Moving on to step 2:
78 divided by 19 is 4 with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 76 from 78, we get 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 19

Moving on to step 3:
If we divide 26 by 19, we get 1 and a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 41.0
Subtracting 19 from 26 leaves us with 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 19

Step 4:
19 can be fit into 70 3 times, resulting in a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 413.0
Subtract 57 from 70 to get 13.
Grab the next digit (2) from the dividend, add it to 13, then carry on: 132 / 19

Going ahead to step 5:
When dividing 132 by 19, we get 6 with a remainder of 18.
Put 6 as the next digit of the answer. 
Result so far: 4136.0
The remainder is 18 after subtracting 114 from 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 6:
19 can be fit into 180 9 times, resulting in a remainder of 9.
The next digit of our result is 9. 
Result so far: 4136.9
If we take 171 away from 180, we end up 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.

Advancing to step 7:
If we divide 90 by 19, we get 4 and a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 4136.94
The remainder is 14 after subtracting 76 from 90.
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 8:
The number 19 fits into 140 7 times, leaving a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 4136.947
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.

Step 9:
19 can be fit into 70 3 times, resulting in a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 4136.9473
Subtract 57 from 70 to get 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 10:
The number 19 fits into 130 6 times, leaving a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 4136.94736
Subtract 114 from 130 to 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.

Moving on to step 11:
If we divide 160 by 19, we get 8 and a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 4136.947368
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.

Let's proceed to step 12:
If we divide 80 by 19, we get 4 and a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 4136.9473684
The remainder is 4 after subtracting 76 from 80.
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 13:
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: 4136.94736842
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.

The final outcome is 4136.94736842, with a leftover of 2e-09.
