We look at the division of 63766020 by 401 
Let's see how many times 401 fits into 63766020.

Moving on to step 1:
401 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 401

Let's proceed to step 2:
If we divide 63 by 401, we get 0 and a remainder of 63.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 63 after subtracting 0 from 63.
Fetch the next digit (7) from the dividend, attach it to 63 and continue: 637 / 401

On to step 3:
401 goes into 637 1 times with a remainder of 236.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 401 from 637, we get 236.
Append the next digit (6) from the dividend to 236 and continue with: 2366 / 401

Advancing to step 4:
401 goes into 2366 5 times with a remainder of 361.
Write down 5 as next digit of the result. 
Result so far: 15.0
Subtract 2005 from 2366 to get 361.
Append the next digit (6) from the dividend to 361 and continue with: 3616 / 401

Advancing to step 5:
If we divide 3616 by 401, we get 9 and a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 159.0
The remainder is 7 after subtracting 3609 from 3616.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 401

Going ahead to step 6:
If we divide 70 by 401, we get 0 and a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 1590.0
Deduct 0 from 70 and we're left with 70.
Append the next digit (2) from the dividend to 70 and continue with: 702 / 401

Moving on to step 7:
702 divided by 401 is 1 with a remainder of 301.
The next digit of our result is 1. 
Result so far: 15901.0
Subtract 401 from 702 to get 301.
Bring next digit (0) of the dividend behind the 301 and repeat the process: 3010 / 401

Moving on to step 8:
If we divide 3010 by 401, we get 7 and a remainder of 203.
Record the quotient 7 as the next digit in the result. 
Result so far: 159017.0
Subtract 2807 from 3010 to get 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Going ahead to step 9:
The number 401 fits into 2030 5 times, leaving a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 159017.5
Subtracting 2005 from 2030 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 10:
401 can be fit into 250 0 times, resulting in a remainder of 250.
Put 0 as the next digit of the answer. 
Result so far: 159017.5
Deduct 0 from 250 and we're left with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Advancing to step 11:
The number 401 fits into 2500 6 times, leaving a remainder of 94.
Put 6 as the next digit of the answer. 
Result so far: 159017.506
Subtract 2406 from 2500 to get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

On to step 12:
If we divide 940 by 401, we get 2 and a remainder of 138.
Put 2 as the next digit of the answer. 
Result so far: 159017.5062
If we take 802 away from 940, we end up with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Step 13:
401 goes into 1380 3 times with a remainder of 177.
Record the quotient 3 as the next digit in the result. 
Result so far: 159017.50623
Subtract 1203 from 1380 to get 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

Going ahead to step 14:
When dividing 1770 by 401, we get 4 with a remainder of 166.
Use 4 as the next digit of our solution. 
Result so far: 159017.506234
If we subtract 1604 from 1770, we get 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Going ahead to step 15:
When dividing 1660 by 401, we get 4 with a remainder of 56.
Put 4 as the next digit of the answer. 
Result so far: 159017.5062344
Deduct 1604 from 1660 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

After the division, we end up with 159017.5062344 and a remainder of 5.6e-07.
