We divide 20450934 by 397
Our goal is to divide 20450934 by 397.

Step 1:
397 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
Deduct 0 from 2 and we're left with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 397

Moving on to step 2:
20 divided by 397 is 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Bring next digit (4) of the dividend behind the 20 and repeat the process: 204 / 397

Let's proceed to step 3:
The number 397 fits into 204 0 times, leaving a remainder of 204.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 204 after subtracting 0 from 204.
Grab the next digit (5) from the dividend, add it to 204, then carry on: 2045 / 397

On to step 4:
2045 divided by 397 is 5 with a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtracting 1985 from 2045 leaves us with 60.
Include the next digit (0) from the dividend after 60, then repeat: 600 / 397

Step 5:
If we divide 600 by 397, we get 1 and a remainder of 203.
Use 1 as the next digit of our solution. 
Result so far: 51.0
If we take 397 away from 600, we end up with 203.
Take the next digit (9) from the dividend and append it to 203, then repeat: 2039 / 397

Moving on to step 6:
2039 divided by 397 is 5 with a remainder of 54.
The number 5 becomes the next digit in our result. 
Result so far: 515.0
Subtracting 1985 from 2039 leaves us with 54.
Bring next digit (3) of the dividend behind the 54 and repeat the process: 543 / 397

Step 7:
When dividing 543 by 397, we get 1 with a remainder of 146.
Use 1 as the next digit of our solution. 
Result so far: 5151.0
If we take 397 away from 543, we end up with 146.
Grab the next digit (4) from the dividend, add it to 146, then carry on: 1464 / 397

Let's proceed to step 8:
1464 divided by 397 is 3 with a remainder of 273.
Record the quotient 3 as the next digit in the result. 
Result so far: 51513.0
Deduct 1191 from 1464 and we're left with 273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

Let's proceed to step 9:
2730 divided by 397 is 6 with a remainder of 348.
Use 6 as the next digit of our solution. 
Result so far: 51513.6
Subtracting 2382 from 2730 leaves us with 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Step 10:
3480 divided by 397 is 8 with a remainder of 304.
The number 8 becomes the next digit in our result. 
Result so far: 51513.68
Deduct 3176 from 3480 and we're left with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Advancing to step 11:
If we divide 3040 by 397, we get 7 and a remainder of 261.
The next digit of our result is 7. 
Result so far: 51513.687
Subtract 2779 from 3040 to get 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

Let's proceed to step 12:
397 can be fit into 2610 6 times, resulting in a remainder of 228.
Use 6 as the next digit of our solution. 
Result so far: 51513.6876
If we subtract 2382 from 2610, we get 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Moving on to step 13:
397 goes into 2280 5 times with a remainder of 295.
Write down 5 as next digit of the result. 
Result so far: 51513.68765
Subtracting 1985 from 2280 leaves us with 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

On to step 14:
397 goes into 2950 7 times with a remainder of 171.
Record the quotient 7 as the next digit in the result. 
Result so far: 51513.687657
If we subtract 2779 from 2950, 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 15:
If we divide 1710 by 397, we get 4 and a remainder of 122.
Record the quotient 4 as the next digit in the result. 
Result so far: 51513.6876574
If we subtract 1588 from 1710, we get 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Advancing to step 16:
397 can be fit into 1220 3 times, resulting in a remainder of 29.
Record the quotient 3 as the next digit in the result. 
Result so far: 51513.68765743
Subtracting 1191 from 1220 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

The final outcome is 51513.68765743, with a leftover of 2.9e-08.
