Let's divide 555649 by 78
Our goal is to divide 555649 by 78.

Advancing to step 1:
When dividing 5 by 78, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 78

Moving on to step 2:
If we divide 55 by 78, we get 0 and a remainder of 55.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 55 leaves us with 55.
Fetch the next digit (5) from the dividend, attach it to 55 and continue: 555 / 78

Let's proceed to step 3:
When dividing 555 by 78, we get 7 with a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtracting 546 from 555 leaves us with 9.
Fetch the next digit (6) from the dividend, attach it to 9 and continue: 96 / 78

Let's proceed to step 4:
If we divide 96 by 78, we get 1 and a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 71.0
Subtract 78 from 96 to get 18.
Grab the next digit (4) from the dividend, add it to 18, then carry on: 184 / 78

Moving on to step 5:
When dividing 184 by 78, we get 2 with a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 712.0
If we take 156 away from 184, we end up with 28.
Bring next digit (9) of the dividend behind the 28 and repeat the process: 289 / 78

On to step 6:
289 divided by 78 is 3 with a remainder of 55.
The number 3 becomes the next digit in our result. 
Result so far: 7123.0
Subtract 234 from 289 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 7:
78 can be fit into 550 7 times, resulting in a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 7123.7
Subtract 546 from 550 to 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.

Step 8:
78 can be fit into 40 0 times, resulting in a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 7123.7
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 9:
If we divide 400 by 78, we get 5 and a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 7123.705
The remainder is 10 after subtracting 390 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 10:
100 divided by 78 is 1 with a remainder of 22.
Put 1 as the next digit of the answer. 
Result so far: 7123.7051
The remainder is 22 after subtracting 78 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 11:
220 divided by 78 is 2 with a remainder of 64.
Write down 2 as next digit of the result. 
Result so far: 7123.70512
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.

Moving on to step 12:
640 divided by 78 is 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 7123.705128
The remainder is 16 after subtracting 624 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 13:
When dividing 160 by 78, we get 2 with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 7123.7051282
The remainder is 4 after subtracting 156 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 14:
78 goes into 40 0 times with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 7123.7051282
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final outcome is 7123.7051282, with a leftover of 4e-08.
