Let's divide 18256590 by 307
We want to figure out the number of times 18256590 can be divided by 307.

Step 1:
307 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 307

Step 2:
307 can be fit into 18 0 times, resulting in a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 18 leaves us with 18.
Append the next digit (2) from the dividend to 18 and continue with: 182 / 307

On to step 3:
The number 307 fits into 182 0 times, leaving a remainder of 182.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 182 and we're left with 182.
Bring next digit (5) of the dividend behind the 182 and repeat the process: 1825 / 307

Moving on to step 4:
1825 divided by 307 is 5 with a remainder of 290.
Use 5 as the next digit of our solution. 
Result so far: 5.0
The remainder is 290 after subtracting 1535 from 1825.
Bring next digit (6) of the dividend behind the 290 and repeat the process: 2906 / 307

Going ahead to step 5:
307 can be fit into 2906 9 times, resulting in a remainder of 143.
The number 9 becomes the next digit in our result. 
Result so far: 59.0
If we subtract 2763 from 2906, we get 143.
Bring next digit (5) of the dividend behind the 143 and repeat the process: 1435 / 307

On to step 6:
307 goes into 1435 4 times with a remainder of 207.
The number 4 becomes the next digit in our result. 
Result so far: 594.0
Deduct 1228 from 1435 and we're left with 207.
Append the next digit (9) from the dividend to 207 and continue with: 2079 / 307

Advancing to step 7:
When dividing 2079 by 307, we get 6 with a remainder of 237.
The next digit of our result is 6. 
Result so far: 5946.0
Subtract 1842 from 2079 to get 237.
Include the next digit (0) from the dividend after 237, then repeat: 2370 / 307

On to step 8:
If we divide 2370 by 307, we get 7 and a remainder of 221.
Use 7 as the next digit of our solution. 
Result so far: 59467.0
The remainder is 221 after subtracting 2149 from 2370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

Going ahead to step 9:
2210 divided by 307 is 7 with a remainder of 61.
The next digit of our result is 7. 
Result so far: 59467.7
Subtract 2149 from 2210 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Going ahead to step 10:
When dividing 610 by 307, we get 1 with a remainder of 303.
The next digit of our result is 1. 
Result so far: 59467.71
If we subtract 307 from 610, we get 303.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3030, and continue the process.

Going ahead to step 11:
When dividing 3030 by 307, we get 9 with a remainder of 267.
Record the quotient 9 as the next digit in the result. 
Result so far: 59467.719
Subtracting 2763 from 3030 leaves us with 267.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

Step 12:
307 goes into 2670 8 times with a remainder of 214.
Record the quotient 8 as the next digit in the result. 
Result so far: 59467.7198
Deduct 2456 from 2670 and we're left with 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Advancing to step 13:
If we divide 2140 by 307, we get 6 and a remainder of 298.
Use 6 as the next digit of our solution. 
Result so far: 59467.71986
If we subtract 1842 from 2140, we get 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Moving on to step 14:
2980 divided by 307 is 9 with a remainder of 217.
Record the quotient 9 as the next digit in the result. 
Result so far: 59467.719869
Deduct 2763 from 2980 and we're left with 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

Moving on to step 15:
2170 divided by 307 is 7 with a remainder of 21.
Use 7 as the next digit of our solution. 
Result so far: 59467.7198697
Subtract 2149 from 2170 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 16:
307 goes into 210 0 times with a remainder of 210.
The number 0 becomes the next digit in our result. 
Result so far: 59467.7198697
Subtract 0 from 210 to get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

In conclusion, the division gives 59467.7198697 with a balance of 2.1e-07.
