We look at the division of 78838671 by 555 
We want to figure out the number of times 78838671 can be divided by 555.

Step 1:
When dividing 7 by 555, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 555

On to step 2:
The number 555 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
Subtracting 0 from 78 leaves us with 78.
Bring next digit (8) of the dividend behind the 78 and repeat the process: 788 / 555

Going ahead to step 3:
555 goes into 788 1 times with a remainder of 233.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 555 from 788 leaves us with 233.
Include the next digit (3) from the dividend after 233, then repeat: 2333 / 555

Going ahead to step 4:
2333 divided by 555 is 4 with a remainder of 113.
Put 4 as the next digit of the answer. 
Result so far: 14.0
The remainder is 113 after subtracting 2220 from 2333.
Bring next digit (8) of the dividend behind the 113 and repeat the process: 1138 / 555

Advancing to step 5:
1138 divided by 555 is 2 with a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 142.0
Subtracting 1110 from 1138 leaves us with 28.
Bring next digit (6) of the dividend behind the 28 and repeat the process: 286 / 555

On to step 6:
555 can be fit into 286 0 times, resulting in a remainder of 286.
The number 0 becomes the next digit in our result. 
Result so far: 1420.0
If we take 0 away from 286, we end up with 286.
Grab the next digit (7) from the dividend, add it to 286, then carry on: 2867 / 555

Let's proceed to step 7:
If we divide 2867 by 555, we get 5 and a remainder of 92.
The next digit of our result is 5. 
Result so far: 14205.0
The remainder is 92 after subtracting 2775 from 2867.
Fetch the next digit (1) from the dividend, attach it to 92 and continue: 921 / 555

On to step 8:
If we divide 921 by 555, we get 1 and a remainder of 366.
The next digit of our result is 1. 
Result so far: 142051.0
If we subtract 555 from 921, we get 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

On to step 9:
555 can be fit into 3660 6 times, resulting in a remainder of 330.
The number 6 becomes the next digit in our result. 
Result so far: 142051.6
If we subtract 3330 from 3660, we get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

On to step 10:
The number 555 fits into 3300 5 times, leaving a remainder of 525.
Write down 5 as next digit of the result. 
Result so far: 142051.65
Deduct 2775 from 3300 and we're left with 525.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5250, and continue the process.

On to step 11:
When dividing 5250 by 555, we get 9 with a remainder of 255.
Write down 9 as next digit of the result. 
Result so far: 142051.659
If we subtract 4995 from 5250, we get 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Let's proceed to step 12:
The number 555 fits into 2550 4 times, leaving a remainder of 330.
Use 4 as the next digit of our solution. 
Result so far: 142051.6594
Subtract 2220 from 2550 to get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Let's proceed to step 13:
The number 555 fits into 3300 5 times, leaving a remainder of 525.
Use 5 as the next digit of our solution. 
Result so far: 142051.65945
Subtracting 2775 from 3300 leaves us with 525.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5250, and continue the process.

Moving on to step 14:
When dividing 5250 by 555, we get 9 with a remainder of 255.
Record the quotient 9 as the next digit in the result. 
Result so far: 142051.659459
Deduct 4995 from 5250 and we're left with 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Moving on to step 15:
555 goes into 2550 4 times with a remainder of 330.
The number 4 becomes the next digit in our result. 
Result so far: 142051.6594594
Deduct 2220 from 2550 and we're left with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Let's proceed to step 16:
555 goes into 3300 5 times with a remainder of 525.
Record the quotient 5 as the next digit in the result. 
Result so far: 142051.65945945
The remainder is 525 after subtracting 2775 from 3300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5250, and continue the process.

Our division results in 142051.65945945 with a remaining 5.25e-07.
