125312 divided by 43 
Our goal is to divide 125312 by 43.

Advancing 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
Subtract 0 from 1 to get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 43

Going ahead to step 2:
43 goes into 12 0 times with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Take the next digit (5) from the dividend and append it to 12, then repeat: 125 / 43

Going ahead to step 3:
If we divide 125 by 43, we get 2 and a remainder of 39.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 86 from 125 and we're left with 39.
Take the next digit (3) from the dividend and append it to 39, then repeat: 393 / 43

Going ahead to step 4:
43 can be fit into 393 9 times, resulting in a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 29.0
The remainder is 6 after subtracting 387 from 393.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 43

Advancing to step 5:
When dividing 61 by 43, we get 1 with a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 291.0
If we subtract 43 from 61, we get 18.
Bring next digit (2) of the dividend behind the 18 and repeat the process: 182 / 43

On to step 6:
When dividing 182 by 43, we get 4 with a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 2914.0
The remainder is 10 after subtracting 172 from 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 7:
43 can be fit into 100 2 times, resulting in a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 2914.2
The remainder is 14 after subtracting 86 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 8:
43 can be fit into 140 3 times, resulting in a remainder of 11.
The next digit of our result is 3. 
Result so far: 2914.23
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.

Moving on to step 9:
43 goes into 110 2 times with a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 2914.232
If we subtract 86 from 110, we get 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 10:
43 goes into 240 5 times with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 2914.2325
Deduct 215 from 240 and we're left 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 11:
The number 43 fits into 250 5 times, leaving a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 2914.23255
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.

The quotient of the division is 2914.23255, and the remainder is 3.5e-05.
