We look at the division of 63131537 by 401 
We want to figure out the number of times 63131537 can be divided by 401.

Step 1:
If we divide 6 by 401, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in 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 / 401

Moving on to step 2:
63 divided by 401 is 0 with a remainder of 63.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 63 and we're left with 63.
Include the next digit (1) from the dividend after 63, then repeat: 631 / 401

Moving on to step 3:
401 can be fit into 631 1 times, resulting in a remainder of 230.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 401 from 631 and we're left with 230.
Append the next digit (3) from the dividend to 230 and continue with: 2303 / 401

Step 4:
401 goes into 2303 5 times with a remainder of 298.
Write down 5 as next digit of the result. 
Result so far: 15.0
Subtract 2005 from 2303 to get 298.
Append the next digit (1) from the dividend to 298 and continue with: 2981 / 401

Let's proceed to step 5:
2981 divided by 401 is 7 with a remainder of 174.
Record the quotient 7 as the next digit in the result. 
Result so far: 157.0
Deduct 2807 from 2981 and we're left with 174.
Take the next digit (5) from the dividend and append it to 174, then repeat: 1745 / 401

Going ahead to step 6:
401 goes into 1745 4 times with a remainder of 141.
Write down 4 as next digit of the result. 
Result so far: 1574.0
The remainder is 141 after subtracting 1604 from 1745.
Append the next digit (3) from the dividend to 141 and continue with: 1413 / 401

On to step 7:
401 goes into 1413 3 times with a remainder of 210.
The number 3 becomes the next digit in our result. 
Result so far: 15743.0
Subtracting 1203 from 1413 leaves us with 210.
Include the next digit (7) from the dividend after 210, then repeat: 2107 / 401

On to step 8:
The number 401 fits into 2107 5 times, leaving a remainder of 102.
Put 5 as the next digit of the answer. 
Result so far: 157435.0
The remainder is 102 after subtracting 2005 from 2107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Step 9:
When dividing 1020 by 401, we get 2 with a remainder of 218.
The next digit of our result is 2. 
Result so far: 157435.2
The remainder is 218 after subtracting 802 from 1020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Advancing to step 10:
The number 401 fits into 2180 5 times, leaving a remainder of 175.
The next digit of our result is 5. 
Result so far: 157435.25
Deduct 2005 from 2180 and we're left with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Going ahead to step 11:
If we divide 1750 by 401, we get 4 and a remainder of 146.
Record the quotient 4 as the next digit in the result. 
Result so far: 157435.254
Subtract 1604 from 1750 to get 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Moving on to step 12:
When dividing 1460 by 401, we get 3 with a remainder of 257.
Write down 3 as next digit of the result. 
Result so far: 157435.2543
Deduct 1203 from 1460 and we're left with 257.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2570, and continue the process.

On to step 13:
401 can be fit into 2570 6 times, resulting in a remainder of 164.
Use 6 as the next digit of our solution. 
Result so far: 157435.25436
If we subtract 2406 from 2570, we get 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Let's proceed to step 14:
401 goes into 1640 4 times with a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 157435.254364
Deduct 1604 from 1640 and we're left 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.

On to step 15:
360 divided by 401 is 0 with a remainder of 360.
Put 0 as the next digit of the answer. 
Result so far: 157435.254364
The remainder is 360 after subtracting 0 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Step 16:
401 can be fit into 3600 8 times, resulting in a remainder of 392.
Write down 8 as next digit of the result. 
Result so far: 157435.25436408
The remainder is 392 after subtracting 3208 from 3600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

The final outcome is 157435.25436408, with a leftover of 3.92e-07.
