We look at the division of 169519 by 43 
Our goal is to divide 169519 by 43.

Let's proceed to step 1:
When dividing 1 by 43, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 43

On to step 2:
16 divided by 43 is 0 with a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 16 leaves us with 16.
Take the next digit (9) from the dividend and append it to 16, then repeat: 169 / 43

Moving on to step 3:
The number 43 fits into 169 3 times, leaving a remainder of 40.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 129 from 169 to get 40.
Grab the next digit (5) from the dividend, add it to 40, then carry on: 405 / 43

Going ahead to step 4:
405 divided by 43 is 9 with a remainder of 18.
Write down 9 as next digit of the result. 
Result so far: 39.0
If we subtract 387 from 405, we get 18.
Take the next digit (1) from the dividend and append it to 18, then repeat: 181 / 43

Moving on to step 5:
43 goes into 181 4 times with a remainder of 9.
Use 4 as the next digit of our solution. 
Result so far: 394.0
The remainder is 9 after subtracting 172 from 181.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 43

Let's proceed to step 6:
When dividing 99 by 43, we get 2 with a remainder of 13.
The number 2 becomes the next digit in our result. 
Result so far: 3942.0
Deduct 86 from 99 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 7:
The number 43 fits into 130 3 times, leaving a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 3942.3
Subtract 129 from 130 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 8:
If we divide 10 by 43, we get 0 and a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 3942.3
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 9:
The number 43 fits into 100 2 times, leaving a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 3942.302
Subtracting 86 from 100 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 10:
The number 43 fits into 140 3 times, leaving a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 3942.3023
Deduct 129 from 140 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 11:
When dividing 110 by 43, we get 2 with a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 3942.30232
Subtracting 86 from 110 leaves us 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.

Step 12:
If we divide 240 by 43, we get 5 and a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 3942.302325
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.

On to step 13:
If we divide 250 by 43, we get 5 and a remainder of 35.
The next digit of our result is 5. 
Result so far: 3942.3023255
The remainder is 35 after subtracting 215 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

After the division, we end up with 3942.3023255 and a remainder of 3.5e-07.
