Let's divide 12020458 by 610
We want to divide 12020458 by 610.

Let's proceed to step 1:
When dividing 1 by 610, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 610

On to step 2:
If we divide 12 by 610, we get 0 and a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Fetch the next digit (0) from the dividend, attach it to 12 and continue: 120 / 610

Step 3:
610 can be fit into 120 0 times, resulting in a remainder of 120.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 120 after subtracting 0 from 120.
Take the next digit (2) from the dividend and append it to 120, then repeat: 1202 / 610

Let's proceed to step 4:
1202 divided by 610 is 1 with a remainder of 592.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 610 from 1202, we get 592.
Take the next digit (0) from the dividend and append it to 592, then repeat: 5920 / 610

Advancing to step 5:
5920 divided by 610 is 9 with a remainder of 430.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
The remainder is 430 after subtracting 5490 from 5920.
Fetch the next digit (4) from the dividend, attach it to 430 and continue: 4304 / 610

Moving on to step 6:
610 can be fit into 4304 7 times, resulting in a remainder of 34.
Write down 7 as next digit of the result. 
Result so far: 197.0
If we take 4270 away from 4304, we end up with 34.
Include the next digit (5) from the dividend after 34, then repeat: 345 / 610

Advancing to step 7:
610 can be fit into 345 0 times, resulting in a remainder of 345.
Record the quotient 0 as the next digit in the result. 
Result so far: 1970.0
The remainder is 345 after subtracting 0 from 345.
Include the next digit (8) from the dividend after 345, then repeat: 3458 / 610

Advancing to step 8:
If we divide 3458 by 610, we get 5 and a remainder of 408.
Use 5 as the next digit of our solution. 
Result so far: 19705.0
If we take 3050 away from 3458, we end up with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Going ahead to step 9:
If we divide 4080 by 610, we get 6 and a remainder of 420.
Use 6 as the next digit of our solution. 
Result so far: 19705.6
If we subtract 3660 from 4080, we get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Step 10:
610 can be fit into 4200 6 times, resulting in a remainder of 540.
The number 6 becomes the next digit in our result. 
Result so far: 19705.66
Deduct 3660 from 4200 and we're left with 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

The quotient of the division is 19705.66, and the remainder is 0.54.
