Let's divide 153870 by 43
We want to divide 153870 by 43.

Advancing to step 1:
43 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 43

Let's proceed to step 2:
15 divided by 43 is 0 with a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Take the next digit (3) from the dividend and append it to 15, then repeat: 153 / 43

Let's proceed to step 3:
The number 43 fits into 153 3 times, leaving a remainder of 24.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 129 from 153 and we're left with 24.
Bring next digit (8) of the dividend behind the 24 and repeat the process: 248 / 43

Going ahead to step 4:
The number 43 fits into 248 5 times, leaving a remainder of 33.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
The remainder is 33 after subtracting 215 from 248.
Include the next digit (7) from the dividend after 33, then repeat: 337 / 43

Going ahead to step 5:
43 goes into 337 7 times with a remainder of 36.
The next digit of our result is 7. 
Result so far: 357.0
If we subtract 301 from 337, we get 36.
Fetch the next digit (0) from the dividend, attach it to 36 and continue: 360 / 43

Let's proceed to step 6:
The number 43 fits into 360 8 times, leaving a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 3578.0
Subtracting 344 from 360 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 7:
When dividing 160 by 43, we get 3 with a remainder of 31.
Put 3 as the next digit of the answer. 
Result so far: 3578.3
Subtract 129 from 160 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 8:
If we divide 310 by 43, we get 7 and a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 3578.37
Subtract 301 from 310 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 9:
43 goes into 90 2 times with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 3578.372
If we subtract 86 from 90, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 10:
The number 43 fits into 40 0 times, leaving a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 3578.372
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 11:
The number 43 fits into 400 9 times, leaving a remainder of 13.
The number 9 becomes the next digit in our result. 
Result so far: 3578.37209
The remainder is 13 after subtracting 387 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 12:
The number 43 fits into 130 3 times, leaving a remainder of 1.
The next digit of our result is 3. 
Result so far: 3578.372093
Subtracting 129 from 130 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 13:
The number 43 fits into 10 0 times, leaving a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 3578.372093
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 14:
43 can be fit into 100 2 times, resulting in a remainder of 14.
The next digit of our result is 2. 
Result so far: 3578.37209302
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.

The quotient of the division is 3578.37209302, and the remainder is 1.4e-08.
