We look at the division of 78705390 by 478 
We want to divide 78705390 by 478.

On to step 1:
The number 478 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 take 0 away from 7, we end up with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 478

Let's proceed to step 2:
The number 478 fits into 78 0 times, leaving a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Fetch the next digit (7) from the dividend, attach it to 78 and continue: 787 / 478

On to step 3:
The number 478 fits into 787 1 times, leaving a remainder of 309.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 478 from 787 leaves us with 309.
Take the next digit (0) from the dividend and append it to 309, then repeat: 3090 / 478

On to step 4:
The number 478 fits into 3090 6 times, leaving a remainder of 222.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
If we take 2868 away from 3090, we end up with 222.
Append the next digit (5) from the dividend to 222 and continue with: 2225 / 478

Moving on to step 5:
If we divide 2225 by 478, we get 4 and a remainder of 313.
The next digit of our result is 4. 
Result so far: 164.0
If we take 1912 away from 2225, we end up with 313.
Take the next digit (3) from the dividend and append it to 313, then repeat: 3133 / 478

Step 6:
478 goes into 3133 6 times with a remainder of 265.
The next digit of our result is 6. 
Result so far: 1646.0
Subtract 2868 from 3133 to get 265.
Append the next digit (9) from the dividend to 265 and continue with: 2659 / 478

Moving on to step 7:
The number 478 fits into 2659 5 times, leaving a remainder of 269.
Write down 5 as next digit of the result. 
Result so far: 16465.0
Subtracting 2390 from 2659 leaves us with 269.
Bring next digit (0) of the dividend behind the 269 and repeat the process: 2690 / 478

Step 8:
When dividing 2690 by 478, we get 5 with a remainder of 300.
The number 5 becomes the next digit in our result. 
Result so far: 164655.0
If we subtract 2390 from 2690, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Advancing to step 9:
The number 478 fits into 3000 6 times, leaving a remainder of 132.
The number 6 becomes the next digit in our result. 
Result so far: 164655.6
If we take 2868 away from 3000, we end up with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Let's proceed to step 10:
The number 478 fits into 1320 2 times, leaving a remainder of 364.
Use 2 as the next digit of our solution. 
Result so far: 164655.62
If we take 956 away from 1320, we end up with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

On to step 11:
When dividing 3640 by 478, we get 7 with a remainder of 294.
The number 7 becomes the next digit in our result. 
Result so far: 164655.627
The remainder is 294 after subtracting 3346 from 3640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Let's proceed to step 12:
When dividing 2940 by 478, we get 6 with a remainder of 72.
Record the quotient 6 as the next digit in the result. 
Result so far: 164655.6276
If we take 2868 away from 2940, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 13:
The number 478 fits into 720 1 times, leaving a remainder of 242.
Write down 1 as next digit of the result. 
Result so far: 164655.62761
Subtracting 478 from 720 leaves us with 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

On to step 14:
478 goes into 2420 5 times with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 164655.627615
If we subtract 2390 from 2420, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 15:
478 can be fit into 300 0 times, resulting in a remainder of 300.
Use 0 as the next digit of our solution. 
Result so far: 164655.627615
The remainder is 300 after subtracting 0 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Going ahead to step 16:
When dividing 3000 by 478, we get 6 with a remainder of 132.
Write down 6 as next digit of the result. 
Result so far: 164655.62761506
The remainder is 132 after subtracting 2868 from 3000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

The final outcome is 164655.62761506, with a leftover of 1.32e-07.
