We divide 43072908 by 138
We want to divide 43072908 by 138.

Step 1:
If we divide 4 by 138, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 138

Advancing to step 2:
43 divided by 138 is 0 with a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 43 after subtracting 0 from 43.
Include the next digit (0) from the dividend after 43, then repeat: 430 / 138

Going ahead to step 3:
When dividing 430 by 138, we get 3 with a remainder of 16.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 414 from 430 leaves us with 16.
Grab the next digit (7) from the dividend, add it to 16, then carry on: 167 / 138

On to step 4:
167 divided by 138 is 1 with a remainder of 29.
Write down 1 as next digit of the result. 
Result so far: 31.0
Subtracting 138 from 167 leaves us with 29.
Grab the next digit (2) from the dividend, add it to 29, then carry on: 292 / 138

Let's proceed to step 5:
The number 138 fits into 292 2 times, leaving a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 312.0
If we take 276 away from 292, we end up with 16.
Fetch the next digit (9) from the dividend, attach it to 16 and continue: 169 / 138

Let's proceed to step 6:
When dividing 169 by 138, we get 1 with a remainder of 31.
Record the quotient 1 as the next digit in the result. 
Result so far: 3121.0
If we take 138 away from 169, we end up with 31.
Fetch the next digit (0) from the dividend, attach it to 31 and continue: 310 / 138

Step 7:
138 can be fit into 310 2 times, resulting in a remainder of 34.
Use 2 as the next digit of our solution. 
Result so far: 31212.0
Subtract 276 from 310 to get 34.
Bring next digit (8) of the dividend behind the 34 and repeat the process: 348 / 138

Let's proceed to step 8:
138 can be fit into 348 2 times, resulting in a remainder of 72.
Use 2 as the next digit of our solution. 
Result so far: 312122.0
Subtracting 276 from 348 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 9:
If we divide 720 by 138, we get 5 and a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 312122.5
If we subtract 690 from 720, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 10:
If we divide 300 by 138, we get 2 and a remainder of 24.
The next digit of our result is 2. 
Result so far: 312122.52
Subtract 276 from 300 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 11:
If we divide 240 by 138, we get 1 and a remainder of 102.
Write down 1 as next digit of the result. 
Result so far: 312122.521
If we take 138 away from 240, we end up with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Moving on to step 12:
1020 divided by 138 is 7 with a remainder of 54.
Record the quotient 7 as the next digit in the result. 
Result so far: 312122.5217
Deduct 966 from 1020 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 13:
When dividing 540 by 138, we get 3 with a remainder of 126.
The next digit of our result is 3. 
Result so far: 312122.52173
Subtracting 414 from 540 leaves us with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Advancing to step 14:
The number 138 fits into 1260 9 times, leaving a remainder of 18.
Put 9 as the next digit of the answer. 
Result so far: 312122.521739
If we take 1242 away from 1260, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 15:
If we divide 180 by 138, we get 1 and a remainder of 42.
Record the quotient 1 as the next digit in the result. 
Result so far: 312122.5217391
Subtracting 138 from 180 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 16:
138 goes into 420 3 times with a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 312122.52173913
Subtracting 414 from 420 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final outcome is 312122.52173913, with a leftover of 6e-09.
