63918965 ÷ 457 
We want to divide 63918965 by 457.

Going ahead to step 1:
457 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 457

Advancing to step 2:
The number 457 fits into 63 0 times, leaving a remainder of 63.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 63 and we're left with 63.
Include the next digit (9) from the dividend after 63, then repeat: 639 / 457

Going ahead to step 3:
If we divide 639 by 457, we get 1 and a remainder of 182.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 457 from 639 and we're left with 182.
Fetch the next digit (1) from the dividend, attach it to 182 and continue: 1821 / 457

On to step 4:
If we divide 1821 by 457, we get 3 and a remainder of 450.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtract 1371 from 1821 to get 450.
Take the next digit (8) from the dividend and append it to 450, then repeat: 4508 / 457

Going ahead to step 5:
457 can be fit into 4508 9 times, resulting in a remainder of 395.
The number 9 becomes the next digit in our result. 
Result so far: 139.0
If we subtract 4113 from 4508, we get 395.
Grab the next digit (9) from the dividend, add it to 395, then carry on: 3959 / 457

Advancing to step 6:
457 can be fit into 3959 8 times, resulting in a remainder of 303.
The next digit of our result is 8. 
Result so far: 1398.0
Deduct 3656 from 3959 and we're left with 303.
Fetch the next digit (6) from the dividend, attach it to 303 and continue: 3036 / 457

Let's proceed to step 7:
If we divide 3036 by 457, we get 6 and a remainder of 294.
The next digit of our result is 6. 
Result so far: 13986.0
The remainder is 294 after subtracting 2742 from 3036.
Append the next digit (5) from the dividend to 294 and continue with: 2945 / 457

Going ahead to step 8:
2945 divided by 457 is 6 with a remainder of 203.
Write down 6 as next digit of the result. 
Result so far: 139866.0
Subtracting 2742 from 2945 leaves us with 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Advancing to step 9:
If we divide 2030 by 457, we get 4 and a remainder of 202.
The number 4 becomes the next digit in our result. 
Result so far: 139866.4
If we take 1828 away from 2030, we end up with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

On to step 10:
457 goes into 2020 4 times with a remainder of 192.
Record the quotient 4 as the next digit in the result. 
Result so far: 139866.44
Subtract 1828 from 2020 to get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Our division results in 139866.44 with a remaining 0.192.
