Let's divide 51323973 by 138
Our goal is to divide 51323973 by 138.

Step 1:
The number 138 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 138

Going ahead to step 2:
The number 138 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 subtract 0 from 51, we get 51.
Append the next digit (3) from the dividend to 51 and continue with: 513 / 138

Moving on to step 3:
When dividing 513 by 138, we get 3 with a remainder of 99.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 414 from 513 and we're left with 99.
Bring next digit (2) of the dividend behind the 99 and repeat the process: 992 / 138

Going ahead to step 4:
138 goes into 992 7 times with a remainder of 26.
The next digit of our result is 7. 
Result so far: 37.0
The remainder is 26 after subtracting 966 from 992.
Fetch the next digit (3) from the dividend, attach it to 26 and continue: 263 / 138

On to step 5:
138 can be fit into 263 1 times, resulting in a remainder of 125.
Write down 1 as next digit of the result. 
Result so far: 371.0
Deduct 138 from 263 and we're left with 125.
Append the next digit (9) from the dividend to 125 and continue with: 1259 / 138

On to step 6:
If we divide 1259 by 138, we get 9 and a remainder of 17.
The next digit of our result is 9. 
Result so far: 3719.0
Deduct 1242 from 1259 and we're left with 17.
Grab the next digit (7) from the dividend, add it to 17, then carry on: 177 / 138

Advancing to step 7:
If we divide 177 by 138, we get 1 and a remainder of 39.
The number 1 becomes the next digit in our result. 
Result so far: 37191.0
If we subtract 138 from 177, we get 39.
Fetch the next digit (3) from the dividend, attach it to 39 and continue: 393 / 138

Moving on to step 8:
138 goes into 393 2 times with a remainder of 117.
The next digit of our result is 2. 
Result so far: 371912.0
Subtracting 276 from 393 leaves us with 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

On to step 9:
When dividing 1170 by 138, we get 8 with a remainder of 66.
Write down 8 as next digit of the result. 
Result so far: 371912.8
Subtract 1104 from 1170 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 10:
The number 138 fits into 660 4 times, leaving a remainder of 108.
Write down 4 as next digit of the result. 
Result so far: 371912.84
Subtract 552 from 660 to get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Going ahead to step 11:
138 goes into 1080 7 times with a remainder of 114.
The next digit of our result is 7. 
Result so far: 371912.847
Deduct 966 from 1080 and we're left with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Let's proceed to step 12:
If we divide 1140 by 138, we get 8 and a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 371912.8478
Deduct 1104 from 1140 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 13:
360 divided by 138 is 2 with a remainder of 84.
Use 2 as the next digit of our solution. 
Result so far: 371912.84782
The remainder is 84 after subtracting 276 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Let's proceed to step 14:
If we divide 840 by 138, we get 6 and a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 371912.847826
Subtracting 828 from 840 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 15:
120 divided by 138 is 0 with a remainder of 120.
Put 0 as the next digit of the answer. 
Result so far: 371912.847826
Subtracting 0 from 120 leaves us 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:
1200 divided by 138 is 8 with a remainder of 96.
Record the quotient 8 as the next digit in the result. 
Result so far: 371912.84782608
Subtracting 1104 from 1200 leaves us with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Our division results in 371912.84782608 with a remaining 9.6e-08.
