We're dividing 43054545 by 138 
Our goal is to divide 43054545 by 138.

Step 1:
If we divide 4 by 138, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 138

Moving on to step 2:
43 divided by 138 is 0 with a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Fetch the next digit (0) from the dividend, attach it to 43 and continue: 430 / 138

Going ahead to step 3:
138 goes into 430 3 times with a remainder of 16.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 414 from 430 and we're left with 16.
Bring next digit (5) of the dividend behind the 16 and repeat the process: 165 / 138

On to step 4:
If we divide 165 by 138, we get 1 and a remainder of 27.
Put 1 as the next digit of the answer. 
Result so far: 31.0
Subtracting 138 from 165 leaves us with 27.
Fetch the next digit (4) from the dividend, attach it to 27 and continue: 274 / 138

Let's proceed to step 5:
If we divide 274 by 138, we get 1 and a remainder of 136.
The number 1 becomes the next digit in our result. 
Result so far: 311.0
If we subtract 138 from 274, we get 136.
Take the next digit (5) from the dividend and append it to 136, then repeat: 1365 / 138

Moving on to step 6:
138 goes into 1365 9 times with a remainder of 123.
The number 9 becomes the next digit in our result. 
Result so far: 3119.0
Subtracting 1242 from 1365 leaves us with 123.
Take the next digit (4) from the dividend and append it to 123, then repeat: 1234 / 138

Advancing to step 7:
138 goes into 1234 8 times with a remainder of 130.
The next digit of our result is 8. 
Result so far: 31198.0
Subtract 1104 from 1234 to get 130.
Append the next digit (5) from the dividend to 130 and continue with: 1305 / 138

Advancing to step 8:
If we divide 1305 by 138, we get 9 and a remainder of 63.
Write down 9 as next digit of the result. 
Result so far: 311989.0
Subtracting 1242 from 1305 leaves us with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Advancing to step 9:
138 goes into 630 4 times with a remainder of 78.
Use 4 as the next digit of our solution. 
Result so far: 311989.4
If we take 552 away from 630, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

On to step 10:
The number 138 fits into 780 5 times, leaving a remainder of 90.
The next digit of our result is 5. 
Result so far: 311989.45
If we subtract 690 from 780, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 11:
When dividing 900 by 138, we get 6 with a remainder of 72.
The next digit of our result is 6. 
Result so far: 311989.456
If we take 828 away from 900, we end up 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 12:
138 can be fit into 720 5 times, resulting in a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 311989.4565
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.

Going ahead to step 13:
138 goes into 300 2 times with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 311989.45652
If we take 276 away from 300, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 14:
When dividing 240 by 138, we get 1 with a remainder of 102.
The next digit of our result is 1. 
Result so far: 311989.456521
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 15:
138 can be fit into 1020 7 times, resulting in a remainder of 54.
Record the quotient 7 as the next digit in the result. 
Result so far: 311989.4565217
If we subtract 966 from 1020, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 16:
The number 138 fits into 540 3 times, leaving a remainder of 126.
Write down 3 as next digit of the result. 
Result so far: 311989.45652173
If we subtract 414 from 540, we get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

In conclusion, the division gives 311989.45652173 with a balance of 1.26e-07.
