We divide 138910 by 43
We want to figure out the number of times 138910 can be divided by 43.

Advancing to step 1:
1 divided by 43 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 43

Let's proceed to step 2:
43 goes into 13 0 times with a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Take the next digit (8) from the dividend and append it to 13, then repeat: 138 / 43

Going ahead to step 3:
43 can be fit into 138 3 times, resulting in a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 129 from 138, we get 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 43

Step 4:
If we divide 99 by 43, we get 2 and a remainder of 13.
The number 2 becomes the next digit in our result. 
Result so far: 32.0
Subtracting 86 from 99 leaves us with 13.
Grab the next digit (1) from the dividend, add it to 13, then carry on: 131 / 43

Step 5:
43 goes into 131 3 times with a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 323.0
Deduct 129 from 131 and we're left with 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 43

Moving on to step 6:
43 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 3230.0
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 7:
If we divide 200 by 43, we get 4 and a remainder of 28.
Record the quotient 4 as the next digit in the result. 
Result so far: 3230.4
Deduct 172 from 200 and we're left 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.

Going ahead to step 8:
If we divide 280 by 43, we get 6 and a remainder of 22.
The next digit of our result is 6. 
Result so far: 3230.46
Subtracting 258 from 280 leaves us 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.

Moving on to step 9:
43 can be fit into 220 5 times, resulting in a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 3230.465
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.

Step 10:
If we divide 50 by 43, we get 1 and a remainder of 7.
The next digit of our result is 1. 
Result so far: 3230.4651
Subtracting 43 from 50 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 11:
When dividing 70 by 43, we get 1 with a remainder of 27.
Record the quotient 1 as the next digit in the result. 
Result so far: 3230.46511
The remainder is 27 after subtracting 43 from 70.
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 result is 3230.46511 with a remainder of 2.7e-05.
