51227290 ÷ 136 
Our goal is to divide 51227290 by 136.

Step 1:
5 divided by 136 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 136

Step 2:
51 divided by 136 is 0 with a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Append the next digit (2) from the dividend to 51 and continue with: 512 / 136

Going ahead to step 3:
136 can be fit into 512 3 times, resulting in a remainder of 104.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 408 from 512 and we're left with 104.
Fetch the next digit (2) from the dividend, attach it to 104 and continue: 1042 / 136

Going ahead to step 4:
The number 136 fits into 1042 7 times, leaving a remainder of 90.
The next digit of our result is 7. 
Result so far: 37.0
If we subtract 952 from 1042, we get 90.
Take the next digit (7) from the dividend and append it to 90, then repeat: 907 / 136

Moving on to step 5:
The number 136 fits into 907 6 times, leaving a remainder of 91.
The number 6 becomes the next digit in our result. 
Result so far: 376.0
Subtracting 816 from 907 leaves us with 91.
Include the next digit (2) from the dividend after 91, then repeat: 912 / 136

Advancing to step 6:
136 goes into 912 6 times with a remainder of 96.
Put 6 as the next digit of the answer. 
Result so far: 3766.0
Subtracting 816 from 912 leaves us with 96.
Take the next digit (9) from the dividend and append it to 96, then repeat: 969 / 136

On to step 7:
969 divided by 136 is 7 with a remainder of 17.
Put 7 as the next digit of the answer. 
Result so far: 37667.0
Subtract 952 from 969 to get 17.
Grab the next digit (0) from the dividend, add it to 17, then carry on: 170 / 136

Advancing to step 8:
If we divide 170 by 136, we get 1 and a remainder of 34.
Record the quotient 1 as the next digit in the result. 
Result so far: 376671.0
Subtracting 136 from 170 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 9:
136 goes into 340 2 times with a remainder of 68.
The number 2 becomes the next digit in our result. 
Result so far: 376671.2
Deduct 272 from 340 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 10:
136 can be fit into 680 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 376671.25
The remainder is 0 after subtracting 680 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 11:
When dividing 0 by 136, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 376671.25
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 12:
When dividing 0 by 136, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 376671.25
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 376671.25 with a remaining 0.0.
