103870 ÷ 43 
We want to figure out the number of times 103870 can be divided by 43.

Moving on to step 1:
43 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 43

Let's proceed to step 2:
43 goes into 10 0 times with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 10 to get 10.
Grab the next digit (3) from the dividend, add it to 10, then carry on: 103 / 43

Going ahead to step 3:
The number 43 fits into 103 2 times, leaving a remainder of 17.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 86 from 103 and we're left with 17.
Fetch the next digit (8) from the dividend, attach it to 17 and continue: 178 / 43

Going ahead to step 4:
43 can be fit into 178 4 times, resulting in a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 24.0
The remainder is 6 after subtracting 172 from 178.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 43

Moving on to step 5:
If we divide 67 by 43, we get 1 and a remainder of 24.
The next digit of our result is 1. 
Result so far: 241.0
Subtracting 43 from 67 leaves us with 24.
Append the next digit (0) from the dividend to 24 and continue with: 240 / 43

Step 6:
If we divide 240 by 43, we get 5 and a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 2415.0
Subtracting 215 from 240 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 7:
250 divided by 43 is 5 with a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 2415.5
If we subtract 215 from 250, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 8:
43 can be fit into 350 8 times, resulting in a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 2415.58
If we take 344 away from 350, we end up 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.

Moving on to step 9:
The number 43 fits into 60 1 times, leaving a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 2415.581
If we subtract 43 from 60, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 10:
43 goes into 170 3 times with a remainder of 41.
Record the quotient 3 as the next digit in the result. 
Result so far: 2415.5813
Subtract 129 from 170 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 11:
43 can be fit into 410 9 times, resulting in a remainder of 23.
The number 9 becomes the next digit in our result. 
Result so far: 2415.58139
The remainder is 23 after subtracting 387 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 12:
230 divided by 43 is 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 2415.581395
If we take 215 away from 230, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 13:
150 divided by 43 is 3 with a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 2415.5813953
If we subtract 129 from 150, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 14:
43 can be fit into 210 4 times, resulting in a remainder of 38.
Write down 4 as next digit of the result. 
Result so far: 2415.58139534
If we take 172 away from 210, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Our division results in 2415.58139534 with a remaining 3.8e-08.
