We look at the division of 78395396 by 966 
We want to divide 78395396 by 966.

Let's proceed to step 1:
When dividing 7 by 966, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 966

Moving on to step 2:
If we divide 78 by 966, we get 0 and a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Fetch the next digit (3) from the dividend, attach it to 78 and continue: 783 / 966

Let's proceed to step 3:
If we divide 783 by 966, we get 0 and a remainder of 783.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 783 after subtracting 0 from 783.
Append the next digit (9) from the dividend to 783 and continue with: 7839 / 966

Step 4:
When dividing 7839 by 966, we get 8 with a remainder of 111.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtracting 7728 from 7839 leaves us with 111.
Take the next digit (5) from the dividend and append it to 111, then repeat: 1115 / 966

On to step 5:
The number 966 fits into 1115 1 times, leaving a remainder of 149.
The number 1 becomes the next digit in our result. 
Result so far: 81.0
If we take 966 away from 1115, we end up with 149.
Include the next digit (3) from the dividend after 149, then repeat: 1493 / 966

Advancing to step 6:
966 goes into 1493 1 times with a remainder of 527.
Use 1 as the next digit of our solution. 
Result so far: 811.0
If we take 966 away from 1493, we end up with 527.
Include the next digit (9) from the dividend after 527, then repeat: 5279 / 966

On to step 7:
5279 divided by 966 is 5 with a remainder of 449.
Write down 5 as next digit of the result. 
Result so far: 8115.0
The remainder is 449 after subtracting 4830 from 5279.
Include the next digit (6) from the dividend after 449, then repeat: 4496 / 966

Advancing to step 8:
When dividing 4496 by 966, we get 4 with a remainder of 632.
Put 4 as the next digit of the answer. 
Result so far: 81154.0
Subtracting 3864 from 4496 leaves us with 632.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

Going ahead to step 9:
If we divide 6320 by 966, we get 6 and a remainder of 524.
Record the quotient 6 as the next digit in the result. 
Result so far: 81154.6
If we subtract 5796 from 6320, we get 524.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

Advancing to step 10:
966 can be fit into 5240 5 times, resulting in a remainder of 410.
Record the quotient 5 as the next digit in the result. 
Result so far: 81154.65
The remainder is 410 after subtracting 4830 from 5240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Step 11:
When dividing 4100 by 966, we get 4 with a remainder of 236.
Put 4 as the next digit of the answer. 
Result so far: 81154.654
If we take 3864 away from 4100, we end up with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Going ahead to step 12:
The number 966 fits into 2360 2 times, leaving a remainder of 428.
Use 2 as the next digit of our solution. 
Result so far: 81154.6542
The remainder is 428 after subtracting 1932 from 2360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Step 13:
966 can be fit into 4280 4 times, resulting in a remainder of 416.
Put 4 as the next digit of the answer. 
Result so far: 81154.65424
Deduct 3864 from 4280 and we're left with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Advancing to step 14:
When dividing 4160 by 966, we get 4 with a remainder of 296.
Use 4 as the next digit of our solution. 
Result so far: 81154.654244
If we take 3864 away from 4160, we end up with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

The final outcome is 81154.654244, with a leftover of 2.96e-05.
