We look at the division of 63485641 by 401 
Our goal is to divide 63485641 by 401.

Going ahead to step 1:
401 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 401

Step 2:
The number 401 fits into 63 0 times, leaving a remainder of 63.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 63, we get 63.
Take the next digit (4) from the dividend and append it to 63, then repeat: 634 / 401

On to step 3:
634 divided by 401 is 1 with a remainder of 233.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 401 from 634 leaves us with 233.
Fetch the next digit (8) from the dividend, attach it to 233 and continue: 2338 / 401

Moving on to step 4:
2338 divided by 401 is 5 with a remainder of 333.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
If we take 2005 away from 2338, we end up with 333.
Take the next digit (5) from the dividend and append it to 333, then repeat: 3335 / 401

Going ahead to step 5:
401 goes into 3335 8 times with a remainder of 127.
The next digit of our result is 8. 
Result so far: 158.0
If we take 3208 away from 3335, we end up with 127.
Fetch the next digit (6) from the dividend, attach it to 127 and continue: 1276 / 401

Moving on to step 6:
401 goes into 1276 3 times with a remainder of 73.
Write down 3 as next digit of the result. 
Result so far: 1583.0
Subtracting 1203 from 1276 leaves us with 73.
Fetch the next digit (4) from the dividend, attach it to 73 and continue: 734 / 401

Advancing to step 7:
If we divide 734 by 401, we get 1 and a remainder of 333.
The next digit of our result is 1. 
Result so far: 15831.0
If we take 401 away from 734, we end up with 333.
Append the next digit (1) from the dividend to 333 and continue with: 3331 / 401

Going ahead to step 8:
401 goes into 3331 8 times with a remainder of 123.
Write down 8 as next digit of the result. 
Result so far: 158318.0
If we subtract 3208 from 3331, we get 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Advancing to step 9:
The number 401 fits into 1230 3 times, leaving a remainder of 27.
Write down 3 as next digit of the result. 
Result so far: 158318.3
Subtract 1203 from 1230 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 10:
270 divided by 401 is 0 with a remainder of 270.
Write down 0 as next digit of the result. 
Result so far: 158318.3
Subtract 0 from 270 to get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Let's proceed to step 11:
The number 401 fits into 2700 6 times, leaving a remainder of 294.
The number 6 becomes the next digit in our result. 
Result so far: 158318.306
The remainder is 294 after subtracting 2406 from 2700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Going ahead to step 12:
401 goes into 2940 7 times with a remainder of 133.
Put 7 as the next digit of the answer. 
Result so far: 158318.3067
If we subtract 2807 from 2940, we get 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Let's proceed to step 13:
1330 divided by 401 is 3 with a remainder of 127.
Record the quotient 3 as the next digit in the result. 
Result so far: 158318.30673
Subtract 1203 from 1330 to get 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Let's proceed to step 14:
1270 divided by 401 is 3 with a remainder of 67.
Record the quotient 3 as the next digit in the result. 
Result so far: 158318.306733
Subtract 1203 from 1270 to get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Our division results in 158318.306733 with a remaining 6.7e-06.
