Let's divide 78978610 by 555
We want to divide 78978610 by 555.

Step 1:
The number 555 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
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 / 555

Step 2:
When dividing 78 by 555, we get 0 with a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Append the next digit (9) from the dividend to 78 and continue with: 789 / 555

Step 3:
555 goes into 789 1 times with a remainder of 234.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 555 from 789 and we're left with 234.
Grab the next digit (7) from the dividend, add it to 234, then carry on: 2347 / 555

Step 4:
2347 divided by 555 is 4 with a remainder of 127.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Deduct 2220 from 2347 and we're left with 127.
Fetch the next digit (8) from the dividend, attach it to 127 and continue: 1278 / 555

Step 5:
1278 divided by 555 is 2 with a remainder of 168.
Write down 2 as next digit of the result. 
Result so far: 142.0
Deduct 1110 from 1278 and we're left with 168.
Append the next digit (6) from the dividend to 168 and continue with: 1686 / 555

On to step 6:
When dividing 1686 by 555, we get 3 with a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 1423.0
The remainder is 21 after subtracting 1665 from 1686.
Bring next digit (1) of the dividend behind the 21 and repeat the process: 211 / 555

Moving on to step 7:
555 goes into 211 0 times with a remainder of 211.
Write down 0 as next digit of the result. 
Result so far: 14230.0
The remainder is 211 after subtracting 0 from 211.
Fetch the next digit (0) from the dividend, attach it to 211 and continue: 2110 / 555

On to step 8:
555 can be fit into 2110 3 times, resulting in a remainder of 445.
The number 3 becomes the next digit in our result. 
Result so far: 142303.0
The remainder is 445 after subtracting 1665 from 2110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

Let's proceed to step 9:
If we divide 4450 by 555, we get 8 and a remainder of 10.
Use 8 as the next digit of our solution. 
Result so far: 142303.8
If we take 4440 away from 4450, we end up 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.

Let's proceed to step 10:
If we divide 100 by 555, we get 0 and a remainder of 100.
The number 0 becomes the next digit in our result. 
Result so far: 142303.8
Subtracting 0 from 100 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 11:
555 goes into 1000 1 times with a remainder of 445.
The number 1 becomes the next digit in our result. 
Result so far: 142303.801
Subtract 555 from 1000 to get 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

On to step 12:
When dividing 4450 by 555, we get 8 with a remainder of 10.
The next digit of our result is 8. 
Result so far: 142303.8018
Subtracting 4440 from 4450 leaves us 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.

Step 13:
When dividing 100 by 555, we get 0 with a remainder of 100.
Record the quotient 0 as the next digit in the result. 
Result so far: 142303.8018
Subtracting 0 from 100 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 14:
555 goes into 1000 1 times with a remainder of 445.
Use 1 as the next digit of our solution. 
Result so far: 142303.801801
Subtract 555 from 1000 to get 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

On to step 15:
The number 555 fits into 4450 8 times, leaving a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 142303.8018018
Deduct 4440 from 4450 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.

On to step 16:
555 goes into 100 0 times with a remainder of 100.
The number 0 becomes the next digit in our result. 
Result so far: 142303.8018018
Deduct 0 from 100 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

In conclusion, the division gives 142303.8018018 with a balance of 1e-07.
