78770 ÷ 51 
We want to divide 78770 by 51.

Going ahead to step 1:
7 divided by 51 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 51

Step 2:
The number 51 fits into 78 1 times, leaving a remainder of 27.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 51 from 78 and we're left with 27.
Grab the next digit (7) from the dividend, add it to 27, then carry on: 277 / 51

Going ahead to step 3:
277 divided by 51 is 5 with a remainder of 22.
Write down 5 as next digit of the result. 
Result so far: 15.0
Subtracting 255 from 277 leaves us with 22.
Take the next digit (7) from the dividend and append it to 22, then repeat: 227 / 51

Let's proceed to step 4:
51 goes into 227 4 times with a remainder of 23.
Put 4 as the next digit of the answer. 
Result so far: 154.0
Subtract 204 from 227 to get 23.
Bring next digit (0) of the dividend behind the 23 and repeat the process: 230 / 51

Let's proceed to step 5:
51 can be fit into 230 4 times, resulting in a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 1544.0
If we take 204 away from 230, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 6:
When dividing 260 by 51, we get 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 1544.5
If we take 255 away from 260, we end up 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.

On to step 7:
50 divided by 51 is 0 with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 1544.5
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 8:
When dividing 500 by 51, we get 9 with a remainder of 41.
Record the quotient 9 as the next digit in the result. 
Result so far: 1544.509
Deduct 459 from 500 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 9:
51 goes into 410 8 times with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 1544.5098
The remainder is 2 after subtracting 408 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 10:
51 goes into 20 0 times with a remainder of 20.
The next digit of our result is 0. 
Result so far: 1544.5098
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 11:
If we divide 200 by 51, we get 3 and a remainder of 47.
Record the quotient 3 as the next digit in the result. 
Result so far: 1544.509803
Subtract 153 from 200 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 12:
470 divided by 51 is 9 with a remainder of 11.
The next digit of our result is 9. 
Result so far: 1544.5098039
Subtracting 459 from 470 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 13:
110 divided by 51 is 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 1544.50980392
Deduct 102 from 110 and we're left 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.

The final outcome is 1544.50980392, with a leftover of 8e-09.
