We're dividing 77776 by 78 
Our goal is to divide 77776 by 78.

Advancing to step 1:
78 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 78

Let's proceed to step 2:
The number 78 fits into 77 0 times, leaving a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Grab the next digit (7) from the dividend, add it to 77, then carry on: 777 / 78

Moving on to step 3:
78 goes into 777 9 times with a remainder of 75.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Deduct 702 from 777 and we're left with 75.
Grab the next digit (7) from the dividend, add it to 75, then carry on: 757 / 78

Advancing to step 4:
78 can be fit into 757 9 times, resulting in a remainder of 55.
The next digit of our result is 9. 
Result so far: 99.0
Deduct 702 from 757 and we're left with 55.
Take the next digit (6) from the dividend and append it to 55, then repeat: 556 / 78

Moving on to step 5:
78 can be fit into 556 7 times, resulting in a remainder of 10.
The next digit of our result is 7. 
Result so far: 997.0
Deduct 546 from 556 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 6:
When dividing 100 by 78, we get 1 with a remainder of 22.
The next digit of our result is 1. 
Result so far: 997.1
If we subtract 78 from 100, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 7:
78 goes into 220 2 times with a remainder of 64.
Put 2 as the next digit of the answer. 
Result so far: 997.12
Subtracting 156 from 220 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 8:
If we divide 640 by 78, we get 8 and a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 997.128
Deduct 624 from 640 and we're left 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.

Step 9:
When dividing 160 by 78, we get 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 997.1282
If we subtract 156 from 160, 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.

On to step 10:
40 divided by 78 is 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 997.1282
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 11:
78 can be fit into 400 5 times, resulting in a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 997.128205
Deduct 390 from 400 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 12:
If we divide 100 by 78, we get 1 and a remainder of 22.
Put 1 as the next digit of the answer. 
Result so far: 997.1282051
Subtract 78 from 100 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 13:
78 can be fit into 220 2 times, resulting in a remainder of 64.
Write down 2 as next digit of the result. 
Result so far: 997.12820512
Deduct 156 from 220 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Our division results in 997.12820512 with a remaining 6.4e-08.
