63952941 ÷ 20 
Our goal is to divide 63952941 by 20.

Advancing to step 1:
20 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 20

Going ahead to step 2:
If we divide 63 by 20, we get 3 and a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 60 from 63 to get 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 20

Going ahead to step 3:
20 goes into 39 1 times with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 31.0
The remainder is 19 after subtracting 20 from 39.
Fetch the next digit (5) from the dividend, attach it to 19 and continue: 195 / 20

Advancing to step 4:
If we divide 195 by 20, we get 9 and a remainder of 15.
Record the quotient 9 as the next digit in the result. 
Result so far: 319.0
If we take 180 away from 195, we end up with 15.
Fetch the next digit (2) from the dividend, attach it to 15 and continue: 152 / 20

Moving on to step 5:
20 goes into 152 7 times with a remainder of 12.
Use 7 as the next digit of our solution. 
Result so far: 3197.0
If we subtract 140 from 152, we get 12.
Bring next digit (9) of the dividend behind the 12 and repeat the process: 129 / 20

Moving on to step 6:
20 can be fit into 129 6 times, resulting in a remainder of 9.
Write down 6 as next digit of the result. 
Result so far: 31976.0
Subtract 120 from 129 to get 9.
Grab the next digit (4) from the dividend, add it to 9, then carry on: 94 / 20

On to step 7:
20 can be fit into 94 4 times, resulting in a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 319764.0
Subtract 80 from 94 to get 14.
Fetch the next digit (1) from the dividend, attach it to 14 and continue: 141 / 20

Let's proceed to step 8:
When dividing 141 by 20, we get 7 with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 3197647.0
If we subtract 140 from 141, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 9:
When dividing 10 by 20, we get 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 3197647.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 10:
The number 20 fits into 100 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 3197647.05
Deduct 100 from 100 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 11:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 3197647.05
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 12:
0 divided by 20 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 3197647.05
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 3197647.05 and a remainder of 0.0.
