We look at the division of 63378417 by 100 
We're looking to find how many times 100 goes into 63378417.

Moving on to step 1:
If we divide 6 by 100, we get 0 and 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.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 100

Step 2:
When dividing 63 by 100, we get 0 with a remainder of 63.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 63 and we're left with 63.
Take the next digit (3) from the dividend and append it to 63, then repeat: 633 / 100

Advancing to step 3:
The number 100 fits into 633 6 times, leaving a remainder of 33.
Use 6 as the next digit of our solution. 
Result so far: 6.0
The remainder is 33 after subtracting 600 from 633.
Include the next digit (7) from the dividend after 33, then repeat: 337 / 100

Step 4:
337 divided by 100 is 3 with a remainder of 37.
Use 3 as the next digit of our solution. 
Result so far: 63.0
Deduct 300 from 337 and we're left with 37.
Bring next digit (8) of the dividend behind the 37 and repeat the process: 378 / 100

Moving on to step 5:
When dividing 378 by 100, we get 3 with a remainder of 78.
Write down 3 as next digit of the result. 
Result so far: 633.0
If we take 300 away from 378, we end up with 78.
Include the next digit (4) from the dividend after 78, then repeat: 784 / 100

Advancing to step 6:
100 goes into 784 7 times with a remainder of 84.
Record the quotient 7 as the next digit in the result. 
Result so far: 6337.0
The remainder is 84 after subtracting 700 from 784.
Append the next digit (1) from the dividend to 84 and continue with: 841 / 100

Step 7:
100 can be fit into 841 8 times, resulting in a remainder of 41.
Write down 8 as next digit of the result. 
Result so far: 63378.0
Subtracting 800 from 841 leaves us with 41.
Grab the next digit (7) from the dividend, add it to 41, then carry on: 417 / 100

On to step 8:
100 goes into 417 4 times with a remainder of 17.
Record the quotient 4 as the next digit in the result. 
Result so far: 633784.0
Subtracting 400 from 417 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 9:
The number 100 fits into 170 1 times, leaving a remainder of 70.
Write down 1 as next digit of the result. 
Result so far: 633784.1
Subtract 100 from 170 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 10:
700 divided by 100 is 7 with a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 633784.17
If we take 700 away from 700, we end up 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.

Advancing to step 11:
The number 100 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 633784.17
Subtracting 0 from 0 leaves us 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.

Advancing to step 12:
100 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 633784.17
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 633784.17, with a leftover of 0.0.
