We divide 16520820 by 307
We're looking to find how many times 307 goes into 16520820.

On to step 1:
307 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 307

On to step 2:
307 can be fit into 16 0 times, resulting in a remainder of 16.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 16 and we're left with 16.
Append the next digit (5) from the dividend to 16 and continue with: 165 / 307

Let's proceed to step 3:
165 divided by 307 is 0 with a remainder of 165.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 165 to get 165.
Bring next digit (2) of the dividend behind the 165 and repeat the process: 1652 / 307

Going ahead to step 4:
When dividing 1652 by 307, we get 5 with a remainder of 117.
The next digit of our result is 5. 
Result so far: 5.0
The remainder is 117 after subtracting 1535 from 1652.
Take the next digit (0) from the dividend and append it to 117, then repeat: 1170 / 307

On to step 5:
1170 divided by 307 is 3 with a remainder of 249.
Use 3 as the next digit of our solution. 
Result so far: 53.0
If we subtract 921 from 1170, we get 249.
Take the next digit (8) from the dividend and append it to 249, then repeat: 2498 / 307

Let's proceed to step 6:
The number 307 fits into 2498 8 times, leaving a remainder of 42.
The next digit of our result is 8. 
Result so far: 538.0
If we subtract 2456 from 2498, we get 42.
Grab the next digit (2) from the dividend, add it to 42, then carry on: 422 / 307

Going ahead to step 7:
307 can be fit into 422 1 times, resulting in a remainder of 115.
Use 1 as the next digit of our solution. 
Result so far: 5381.0
Subtract 307 from 422 to get 115.
Bring next digit (0) of the dividend behind the 115 and repeat the process: 1150 / 307

Step 8:
The number 307 fits into 1150 3 times, leaving a remainder of 229.
Write down 3 as next digit of the result. 
Result so far: 53813.0
Subtract 921 from 1150 to get 229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

Step 9:
307 goes into 2290 7 times with a remainder of 141.
Put 7 as the next digit of the answer. 
Result so far: 53813.7
The remainder is 141 after subtracting 2149 from 2290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

On to step 10:
307 goes into 1410 4 times with a remainder of 182.
The next digit of our result is 4. 
Result so far: 53813.74
Subtract 1228 from 1410 to get 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Step 11:
307 can be fit into 1820 5 times, resulting in a remainder of 285.
Put 5 as the next digit of the answer. 
Result so far: 53813.745
Subtracting 1535 from 1820 leaves us with 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Moving on to step 12:
307 can be fit into 2850 9 times, resulting in a remainder of 87.
The number 9 becomes the next digit in our result. 
Result so far: 53813.7459
If we take 2763 away from 2850, we end up with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Going ahead to step 13:
870 divided by 307 is 2 with a remainder of 256.
Record the quotient 2 as the next digit in the result. 
Result so far: 53813.74592
If we take 614 away from 870, we end up with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Moving on to step 14:
The number 307 fits into 2560 8 times, leaving a remainder of 104.
Put 8 as the next digit of the answer. 
Result so far: 53813.745928
Subtract 2456 from 2560 to get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

On to step 15:
1040 divided by 307 is 3 with a remainder of 119.
Put 3 as the next digit of the answer. 
Result so far: 53813.7459283
If we take 921 away from 1040, we end up with 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Step 16:
307 can be fit into 1190 3 times, resulting in a remainder of 269.
The next digit of our result is 3. 
Result so far: 53813.74592833
Subtract 921 from 1190 to get 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

The final outcome is 53813.74592833, with a leftover of 2.69e-07.
