51921220 ÷ 136 
We want to divide 51921220 by 136.

Advancing to step 1:
136 goes into 5 0 times 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.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 136

Moving on to step 2:
The number 136 fits into 51 0 times, leaving a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Append the next digit (9) from the dividend to 51 and continue with: 519 / 136

Moving on to step 3:
136 can be fit into 519 3 times, resulting in a remainder of 111.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 408 from 519 to get 111.
Bring next digit (2) of the dividend behind the 111 and repeat the process: 1112 / 136

Moving on to step 4:
The number 136 fits into 1112 8 times, leaving a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 38.0
Subtracting 1088 from 1112 leaves us with 24.
Take the next digit (1) from the dividend and append it to 24, then repeat: 241 / 136

Step 5:
If we divide 241 by 136, we get 1 and a remainder of 105.
Put 1 as the next digit of the answer. 
Result so far: 381.0
The remainder is 105 after subtracting 136 from 241.
Grab the next digit (2) from the dividend, add it to 105, then carry on: 1052 / 136

Let's proceed to step 6:
The number 136 fits into 1052 7 times, leaving a remainder of 100.
Write down 7 as next digit of the result. 
Result so far: 3817.0
If we subtract 952 from 1052, we get 100.
Include the next digit (2) from the dividend after 100, then repeat: 1002 / 136

Going ahead to step 7:
1002 divided by 136 is 7 with a remainder of 50.
Put 7 as the next digit of the answer. 
Result so far: 38177.0
Subtract 952 from 1002 to get 50.
Fetch the next digit (0) from the dividend, attach it to 50 and continue: 500 / 136

Let's proceed to step 8:
If we divide 500 by 136, we get 3 and a remainder of 92.
The number 3 becomes the next digit in our result. 
Result so far: 381773.0
Subtracting 408 from 500 leaves us with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Step 9:
If we divide 920 by 136, we get 6 and a remainder of 104.
Write down 6 as next digit of the result. 
Result so far: 381773.6
Deduct 816 from 920 and we're left with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Let's proceed to step 10:
136 goes into 1040 7 times with a remainder of 88.
Write down 7 as next digit of the result. 
Result so far: 381773.67
If we take 952 away from 1040, we end up with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Let's proceed to step 11:
When dividing 880 by 136, we get 6 with a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 381773.676
If we subtract 816 from 880, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 12:
136 can be fit into 640 4 times, resulting in a remainder of 96.
The number 4 becomes the next digit in our result. 
Result so far: 381773.6764
Subtract 544 from 640 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Moving on to step 13:
When dividing 960 by 136, we get 7 with a remainder of 8.
Use 7 as the next digit of our solution. 
Result so far: 381773.67647
Subtracting 952 from 960 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 14:
136 can be fit into 80 0 times, resulting in a remainder of 80.
The next digit of our result is 0. 
Result so far: 381773.67647
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 15:
When dividing 800 by 136, we get 5 with a remainder of 120.
Use 5 as the next digit of our solution. 
Result so far: 381773.6764705
Deduct 680 from 800 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 16:
If we divide 1200 by 136, we get 8 and a remainder of 112.
Use 8 as the next digit of our solution. 
Result so far: 381773.67647058
Deduct 1088 from 1200 and we're left with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

The final result is 381773.67647058 with a remainder of 1.12e-07.
