We want to divide 20450521 by 683.

Moving on to step 1:
683 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 683

Let's proceed to step 2:
20 divided by 683 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Include the next digit (4) from the dividend after 20, then repeat: 204 / 683

Let's proceed to step 3:
The number 683 fits into 204 0 times, leaving a remainder of 204.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 204 and we're left with 204.
Include the next digit (5) from the dividend after 204, then repeat: 2045 / 683

Let's proceed to step 4:
683 goes into 2045 2 times with a remainder of 679.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 1366 from 2045, we get 679.
Include the next digit (0) from the dividend after 679, then repeat: 6790 / 683

Let's proceed to step 5:
6790 divided by 683 is 9 with a remainder of 643.
Record the quotient 9 as the next digit in the result. 
Result so far: 29.0
Deduct 6147 from 6790 and we're left with 643.
Take the next digit (5) from the dividend and append it to 643, then repeat: 6435 / 683

Advancing to step 6:
6435 divided by 683 is 9 with a remainder of 288.
The number 9 becomes the next digit in our result. 
Result so far: 299.0
The remainder is 288 after subtracting 6147 from 6435.
Include the next digit (2) from the dividend after 288, then repeat: 2882 / 683

Going ahead to step 7:
683 goes into 2882 4 times with a remainder of 150.
Record the quotient 4 as the next digit in the result. 
Result so far: 2994.0
If we subtract 2732 from 2882, we get 150.
Take the next digit (1) from the dividend and append it to 150, then repeat: 1501 / 683

Let's proceed to step 8:
When dividing 1501 by 683, we get 2 with a remainder of 135.
Use 2 as the next digit of our solution. 
Result so far: 29942.0
Subtracting 1366 from 1501 leaves us with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Advancing to step 9:
The number 683 fits into 1350 1 times, leaving a remainder of 667.
The number 1 becomes the next digit in our result. 
Result so far: 29942.1
The remainder is 667 after subtracting 683 from 1350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6670, and continue the process.

Let's proceed to step 10:
When dividing 6670 by 683, we get 9 with a remainder of 523.
Put 9 as the next digit of the answer. 
Result so far: 29942.19
Deduct 6147 from 6670 and we're left with 523.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5230, and continue the process.

Advancing to step 11:
If we divide 5230 by 683, we get 7 and a remainder of 449.
Record the quotient 7 as the next digit in the result. 
Result so far: 29942.197
Deduct 4781 from 5230 and we're left with 449.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4490, and continue the process.

Let's proceed to step 12:
683 goes into 4490 6 times with a remainder of 392.
Use 6 as the next digit of our solution. 
Result so far: 29942.1976
Deduct 4098 from 4490 and we're left with 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Advancing to step 13:
If we divide 3920 by 683, we get 5 and a remainder of 505.
Put 5 as the next digit of the answer. 
Result so far: 29942.19765
Subtract 3415 from 3920 to get 505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

Moving on to step 14:
683 goes into 5050 7 times with a remainder of 269.
The number 7 becomes the next digit in our result. 
Result so far: 29942.197657
If we subtract 4781 from 5050, we 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.

On to step 15:
2690 divided by 683 is 3 with a remainder of 641.
The next digit of our result is 3. 
Result so far: 29942.1976573
Subtracting 2049 from 2690 leaves us with 641.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6410, and continue the process.

Moving on to step 16:
683 can be fit into 6410 9 times, resulting in a remainder of 263.
Put 9 as the next digit of the answer. 
Result so far: 29942.19765739
Subtracting 6147 from 6410 leaves us with 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

The final outcome is 29942.19765739, with a leftover of 2.63e-07.
