Let's divide 77860 by 19
Let's see how many times 19 fits into 77860.

On to step 1:
The number 19 fits into 7 0 times, leaving 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.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 19

Moving on to step 2:
The number 19 fits into 77 4 times, leaving a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 76 away from 77, we end up with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 19

Step 3:
The number 19 fits into 18 0 times, leaving a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 40.0
If we subtract 0 from 18, we get 18.
Grab the next digit (6) from the dividend, add it to 18, then carry on: 186 / 19

Going ahead to step 4:
If we divide 186 by 19, we get 9 and a remainder of 15.
The next digit of our result is 9. 
Result so far: 409.0
Subtract 171 from 186 to get 15.
Bring next digit (0) of the dividend behind the 15 and repeat the process: 150 / 19

Going ahead to step 5:
19 goes into 150 7 times with a remainder of 17.
The next digit of our result is 7. 
Result so far: 4097.0
Subtract 133 from 150 to get 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 6:
19 goes into 170 8 times with a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 4097.8
The remainder is 18 after subtracting 152 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 7:
If we divide 180 by 19, we get 9 and a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 4097.89
Deduct 171 from 180 and we're left 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.

Let's proceed to step 8:
The number 19 fits into 90 4 times, leaving a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 4097.894
If we subtract 76 from 90, we 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.

On to step 9:
When dividing 140 by 19, we get 7 with a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 4097.8947
If we subtract 133 from 140, 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.

Moving on to step 10:
19 goes into 70 3 times with a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 4097.89473
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.

Advancing to step 11:
19 can be fit into 130 6 times, resulting in a remainder of 16.
The next digit of our result is 6. 
Result so far: 4097.894736
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.

Moving on to step 12:
19 goes into 160 8 times with a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 4097.8947368
Subtract 152 from 160 to 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.

Moving on to step 13:
19 can be fit into 80 4 times, resulting in a remainder of 4.
The next digit of our result is 4. 
Result so far: 4097.89473684
If we subtract 76 from 80, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final outcome is 4097.89473684, with a leftover of 4e-09.
