We look at the division of 51655351 by 138 
Let's see how many times 138 fits into 51655351.

On to step 1:
If we divide 5 by 138, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 138

Let's proceed to step 2:
When dividing 51 by 138, we get 0 with a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Take the next digit (6) from the dividend and append it to 51, then repeat: 516 / 138

Step 3:
The number 138 fits into 516 3 times, leaving a remainder of 102.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 414 from 516 leaves us with 102.
Append the next digit (5) from the dividend to 102 and continue with: 1025 / 138

Let's proceed to step 4:
If we divide 1025 by 138, we get 7 and a remainder of 59.
The number 7 becomes the next digit in our result. 
Result so far: 37.0
Subtracting 966 from 1025 leaves us with 59.
Include the next digit (5) from the dividend after 59, then repeat: 595 / 138

On to step 5:
If we divide 595 by 138, we get 4 and a remainder of 43.
The next digit of our result is 4. 
Result so far: 374.0
Subtract 552 from 595 to get 43.
Bring next digit (3) of the dividend behind the 43 and repeat the process: 433 / 138

Step 6:
138 goes into 433 3 times with a remainder of 19.
Use 3 as the next digit of our solution. 
Result so far: 3743.0
Subtract 414 from 433 to get 19.
Bring next digit (5) of the dividend behind the 19 and repeat the process: 195 / 138

On to step 7:
When dividing 195 by 138, we get 1 with a remainder of 57.
Put 1 as the next digit of the answer. 
Result so far: 37431.0
If we subtract 138 from 195, we get 57.
Grab the next digit (1) from the dividend, add it to 57, then carry on: 571 / 138

Going ahead to step 8:
138 can be fit into 571 4 times, resulting in a remainder of 19.
Write down 4 as next digit of the result. 
Result so far: 374314.0
The remainder is 19 after subtracting 552 from 571.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 9:
The number 138 fits into 190 1 times, leaving a remainder of 52.
The number 1 becomes the next digit in our result. 
Result so far: 374314.1
The remainder is 52 after subtracting 138 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 10:
The number 138 fits into 520 3 times, leaving a remainder of 106.
The number 3 becomes the next digit in our result. 
Result so far: 374314.13
Subtract 414 from 520 to get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Let's proceed to step 11:
1060 divided by 138 is 7 with a remainder of 94.
Put 7 as the next digit of the answer. 
Result so far: 374314.137
If we take 966 away from 1060, we end up with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Step 12:
When dividing 940 by 138, we get 6 with a remainder of 112.
Write down 6 as next digit of the result. 
Result so far: 374314.1376
Subtracting 828 from 940 leaves us 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.

Step 13:
1120 divided by 138 is 8 with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 374314.13768
The remainder is 16 after subtracting 1104 from 1120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 14:
If we divide 160 by 138, we get 1 and a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 374314.137681
If we subtract 138 from 160, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 15:
The number 138 fits into 220 1 times, leaving a remainder of 82.
Use 1 as the next digit of our solution. 
Result so far: 374314.1376811
If we take 138 away from 220, we end up with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Our division results in 374314.1376811 with a remaining 8.2e-07.
