We divide 20491807 by 307
Our goal is to divide 20491807 by 307.

Going ahead to step 1:
307 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 307

Going ahead to step 2:
20 divided by 307 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Append the next digit (4) from the dividend to 20 and continue with: 204 / 307

Let's proceed to step 3:
If we divide 204 by 307, we get 0 and a remainder of 204.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 204 to get 204.
Fetch the next digit (9) from the dividend, attach it to 204 and continue: 2049 / 307

Let's proceed to step 4:
When dividing 2049 by 307, we get 6 with a remainder of 207.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we subtract 1842 from 2049, we get 207.
Grab the next digit (1) from the dividend, add it to 207, then carry on: 2071 / 307

Going ahead to step 5:
307 goes into 2071 6 times with a remainder of 229.
Write down 6 as next digit of the result. 
Result so far: 66.0
Deduct 1842 from 2071 and we're left with 229.
Append the next digit (8) from the dividend to 229 and continue with: 2298 / 307

Going ahead to step 6:
307 goes into 2298 7 times with a remainder of 149.
Write down 7 as next digit of the result. 
Result so far: 667.0
If we take 2149 away from 2298, we end up with 149.
Include the next digit (0) from the dividend after 149, then repeat: 1490 / 307

Going ahead to step 7:
307 goes into 1490 4 times with a remainder of 262.
The number 4 becomes the next digit in our result. 
Result so far: 6674.0
Deduct 1228 from 1490 and we're left with 262.
Take the next digit (7) from the dividend and append it to 262, then repeat: 2627 / 307

Advancing to step 8:
If we divide 2627 by 307, we get 8 and a remainder of 171.
The number 8 becomes the next digit in our result. 
Result so far: 66748.0
If we subtract 2456 from 2627, we get 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

On to step 9:
If we divide 1710 by 307, we get 5 and a remainder of 175.
Record the quotient 5 as the next digit in the result. 
Result so far: 66748.5
If we subtract 1535 from 1710, we get 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Going ahead to step 10:
307 can be fit into 1750 5 times, resulting in a remainder of 215.
Use 5 as the next digit of our solution. 
Result so far: 66748.55
Deduct 1535 from 1750 and we're left with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

The final outcome is 66748.55, with a leftover of 0.215.
