Let's divide 55151137 by 678
Let's see how many times 678 fits into 55151137.

Step 1:
5 divided by 678 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 678

Advancing to step 2:
678 can be fit into 55 0 times, resulting in a remainder of 55.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 55 to get 55.
Grab the next digit (1) from the dividend, add it to 55, then carry on: 551 / 678

Advancing to step 3:
When dividing 551 by 678, we get 0 with a remainder of 551.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 551 leaves us with 551.
Append the next digit (5) from the dividend to 551 and continue with: 5515 / 678

Let's proceed to step 4:
If we divide 5515 by 678, we get 8 and a remainder of 91.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we take 5424 away from 5515, we end up with 91.
Take the next digit (1) from the dividend and append it to 91, then repeat: 911 / 678

Let's proceed to step 5:
678 can be fit into 911 1 times, resulting in a remainder of 233.
Write down 1 as next digit of the result. 
Result so far: 81.0
The remainder is 233 after subtracting 678 from 911.
Take the next digit (1) from the dividend and append it to 233, then repeat: 2331 / 678

Going ahead to step 6:
If we divide 2331 by 678, we get 3 and a remainder of 297.
The next digit of our result is 3. 
Result so far: 813.0
If we take 2034 away from 2331, we end up with 297.
Include the next digit (3) from the dividend after 297, then repeat: 2973 / 678

Advancing to step 7:
2973 divided by 678 is 4 with a remainder of 261.
The number 4 becomes the next digit in our result. 
Result so far: 8134.0
Deduct 2712 from 2973 and we're left with 261.
Take the next digit (7) from the dividend and append it to 261, then repeat: 2617 / 678

Advancing to step 8:
678 goes into 2617 3 times with a remainder of 583.
Write down 3 as next digit of the result. 
Result so far: 81343.0
The remainder is 583 after subtracting 2034 from 2617.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5830, and continue the process.

On to step 9:
The number 678 fits into 5830 8 times, leaving a remainder of 406.
Record the quotient 8 as the next digit in the result. 
Result so far: 81343.8
If we subtract 5424 from 5830, we get 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Step 10:
678 can be fit into 4060 5 times, resulting in a remainder of 670.
The number 5 becomes the next digit in our result. 
Result so far: 81343.85
Subtracting 3390 from 4060 leaves us with 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

Going ahead to step 11:
6700 divided by 678 is 9 with a remainder of 598.
The number 9 becomes the next digit in our result. 
Result so far: 81343.859
Deduct 6102 from 6700 and we're left with 598.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5980, and continue the process.

On to step 12:
678 can be fit into 5980 8 times, resulting in a remainder of 556.
Record the quotient 8 as the next digit in the result. 
Result so far: 81343.8598
Subtracting 5424 from 5980 leaves us with 556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

Let's proceed to step 13:
The number 678 fits into 5560 8 times, leaving a remainder of 136.
The number 8 becomes the next digit in our result. 
Result so far: 81343.85988
Subtract 5424 from 5560 to get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

The final outcome is 81343.85988, with a leftover of 0.000136.
