Let's divide 12309108 by 610
We want to divide 12309108 by 610.

Let's proceed to step 1:
The number 610 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 610

Let's proceed to step 2:
610 goes into 12 0 times with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Include the next digit (3) from the dividend after 12, then repeat: 123 / 610

Moving on to step 3:
If we divide 123 by 610, we get 0 and a remainder of 123.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 123 leaves us with 123.
Fetch the next digit (0) from the dividend, attach it to 123 and continue: 1230 / 610

Let's proceed to step 4:
When dividing 1230 by 610, we get 2 with a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 1220 from 1230 leaves us with 10.
Grab the next digit (9) from the dividend, add it to 10, then carry on: 109 / 610

Moving on to step 5:
109 divided by 610 is 0 with a remainder of 109.
Write down 0 as next digit of the result. 
Result so far: 20.0
Deduct 0 from 109 and we're left with 109.
Include the next digit (1) from the dividend after 109, then repeat: 1091 / 610

On to step 6:
610 goes into 1091 1 times with a remainder of 481.
Put 1 as the next digit of the answer. 
Result so far: 201.0
Subtracting 610 from 1091 leaves us with 481.
Take the next digit (0) from the dividend and append it to 481, then repeat: 4810 / 610

Moving on to step 7:
610 can be fit into 4810 7 times, resulting in a remainder of 540.
Record the quotient 7 as the next digit in the result. 
Result so far: 2017.0
If we take 4270 away from 4810, we end up with 540.
Fetch the next digit (8) from the dividend, attach it to 540 and continue: 5408 / 610

Going ahead to step 8:
610 can be fit into 5408 8 times, resulting in a remainder of 528.
Write down 8 as next digit of the result. 
Result so far: 20178.0
Subtracting 4880 from 5408 leaves us with 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Let's proceed to step 9:
The number 610 fits into 5280 8 times, leaving a remainder of 400.
Use 8 as the next digit of our solution. 
Result so far: 20178.8
Deduct 4880 from 5280 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Moving on to step 10:
4000 divided by 610 is 6 with a remainder of 340.
Use 6 as the next digit of our solution. 
Result so far: 20178.86
If we subtract 3660 from 4000, we get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Let's proceed to step 11:
If we divide 3400 by 610, we get 5 and a remainder of 350.
Write down 5 as next digit of the result. 
Result so far: 20178.865
Subtract 3050 from 3400 to get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Moving on to step 12:
The number 610 fits into 3500 5 times, leaving a remainder of 450.
Put 5 as the next digit of the answer. 
Result so far: 20178.8655
Deduct 3050 from 3500 and we're left with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

After the division, we end up with 20178.8655 and a remainder of 0.0045.
