We divide 138351 by 43
Our goal is to divide 138351 by 43.

Advancing to step 1:
1 divided by 43 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 43

Step 2:
13 divided by 43 is 0 with a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 13, we end up with 13.
Include the next digit (8) from the dividend after 13, then repeat: 138 / 43

Going ahead to step 3:
138 divided by 43 is 3 with a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 9 after subtracting 129 from 138.
Bring next digit (3) of the dividend behind the 9 and repeat the process: 93 / 43

Going ahead to step 4:
The number 43 fits into 93 2 times, leaving a remainder of 7.
Write down 2 as next digit of the result. 
Result so far: 32.0
If we subtract 86 from 93, we get 7.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 43

Let's proceed to step 5:
If we divide 75 by 43, we get 1 and a remainder of 32.
Use 1 as the next digit of our solution. 
Result so far: 321.0
Subtracting 43 from 75 leaves us with 32.
Include the next digit (1) from the dividend after 32, then repeat: 321 / 43

Step 6:
If we divide 321 by 43, we get 7 and a remainder of 20.
Put 7 as the next digit of the answer. 
Result so far: 3217.0
The remainder is 20 after subtracting 301 from 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 7:
When dividing 200 by 43, we get 4 with a remainder of 28.
The next digit of our result is 4. 
Result so far: 3217.4
If we take 172 away from 200, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 8:
43 goes into 280 6 times with a remainder of 22.
The number 6 becomes the next digit in our result. 
Result so far: 3217.46
Deduct 258 from 280 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 9:
When dividing 220 by 43, we get 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 3217.465
The remainder is 5 after subtracting 215 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 10:
43 can be fit into 50 1 times, resulting in a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 3217.4651
Subtract 43 from 50 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 11:
When dividing 70 by 43, we get 1 with a remainder of 27.
The next digit of our result is 1. 
Result so far: 3217.46511
Subtracting 43 from 70 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

The final outcome is 3217.46511, with a leftover of 2.7e-05.
