We look at the division of 63641787 by 478 
We're looking to find how many times 478 goes into 63641787.

Going ahead to step 1:
The number 478 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 478

Let's proceed to step 2:
The number 478 fits into 63 0 times, leaving a remainder of 63.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 63, we get 63.
Grab the next digit (6) from the dividend, add it to 63, then carry on: 636 / 478

Going ahead to step 3:
478 can be fit into 636 1 times, resulting in a remainder of 158.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 478 from 636 leaves us with 158.
Take the next digit (4) from the dividend and append it to 158, then repeat: 1584 / 478

Step 4:
478 goes into 1584 3 times with a remainder of 150.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we take 1434 away from 1584, we end up with 150.
Fetch the next digit (1) from the dividend, attach it to 150 and continue: 1501 / 478

Going ahead to step 5:
When dividing 1501 by 478, we get 3 with a remainder of 67.
Use 3 as the next digit of our solution. 
Result so far: 133.0
Deduct 1434 from 1501 and we're left with 67.
Include the next digit (7) from the dividend after 67, then repeat: 677 / 478

On to step 6:
478 can be fit into 677 1 times, resulting in a remainder of 199.
Use 1 as the next digit of our solution. 
Result so far: 1331.0
The remainder is 199 after subtracting 478 from 677.
Append the next digit (8) from the dividend to 199 and continue with: 1998 / 478

Step 7:
478 goes into 1998 4 times with a remainder of 86.
Write down 4 as next digit of the result. 
Result so far: 13314.0
The remainder is 86 after subtracting 1912 from 1998.
Fetch the next digit (7) from the dividend, attach it to 86 and continue: 867 / 478

Step 8:
867 divided by 478 is 1 with a remainder of 389.
Put 1 as the next digit of the answer. 
Result so far: 133141.0
If we subtract 478 from 867, we get 389.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3890, and continue the process.

Advancing to step 9:
478 can be fit into 3890 8 times, resulting in a remainder of 66.
The number 8 becomes the next digit in our result. 
Result so far: 133141.8
Subtracting 3824 from 3890 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 10:
When dividing 660 by 478, we get 1 with a remainder of 182.
Record the quotient 1 as the next digit in the result. 
Result so far: 133141.81
If we take 478 away from 660, we end up with 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Step 11:
1820 divided by 478 is 3 with a remainder of 386.
Write down 3 as next digit of the result. 
Result so far: 133141.813
If we subtract 1434 from 1820, we get 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Step 12:
478 can be fit into 3860 8 times, resulting in a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 133141.8138
If we take 3824 away from 3860, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 13:
478 can be fit into 360 0 times, resulting in a remainder of 360.
Use 0 as the next digit of our solution. 
Result so far: 133141.8138
Deduct 0 from 360 and we're left with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Moving on to step 14:
When dividing 3600 by 478, we get 7 with a remainder of 254.
Put 7 as the next digit of the answer. 
Result so far: 133141.813807
Deduct 3346 from 3600 and we're left with 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Let's proceed to step 15:
2540 divided by 478 is 5 with a remainder of 150.
The next digit of our result is 5. 
Result so far: 133141.8138075
Deduct 2390 from 2540 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Advancing to step 16:
If we divide 1500 by 478, we get 3 and a remainder of 66.
Put 3 as the next digit of the answer. 
Result so far: 133141.81380753
Deduct 1434 from 1500 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

The quotient of the division is 133141.81380753, and the remainder is 6.6e-08.
