We're dividing 63857887 by 369 
We want to divide 63857887 by 369.

Going ahead to step 1:
When dividing 6 by 369, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
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 / 369

Advancing to step 2:
369 can be fit into 63 0 times, resulting in a remainder of 63.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 63 leaves us with 63.
Append the next digit (8) from the dividend to 63 and continue with: 638 / 369

Advancing to step 3:
638 divided by 369 is 1 with a remainder of 269.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 369 away from 638, we end up with 269.
Fetch the next digit (5) from the dividend, attach it to 269 and continue: 2695 / 369

On to step 4:
The number 369 fits into 2695 7 times, leaving a remainder of 112.
The next digit of our result is 7. 
Result so far: 17.0
If we take 2583 away from 2695, we end up with 112.
Append the next digit (7) from the dividend to 112 and continue with: 1127 / 369

Let's proceed to step 5:
The number 369 fits into 1127 3 times, leaving a remainder of 20.
Write down 3 as next digit of the result. 
Result so far: 173.0
Subtract 1107 from 1127 to get 20.
Include the next digit (8) from the dividend after 20, then repeat: 208 / 369

On to step 6:
If we divide 208 by 369, we get 0 and a remainder of 208.
The number 0 becomes the next digit in our result. 
Result so far: 1730.0
The remainder is 208 after subtracting 0 from 208.
Bring next digit (8) of the dividend behind the 208 and repeat the process: 2088 / 369

Moving on to step 7:
369 can be fit into 2088 5 times, resulting in a remainder of 243.
Record the quotient 5 as the next digit in the result. 
Result so far: 17305.0
The remainder is 243 after subtracting 1845 from 2088.
Bring next digit (7) of the dividend behind the 243 and repeat the process: 2437 / 369

On to step 8:
369 can be fit into 2437 6 times, resulting in a remainder of 223.
The next digit of our result is 6. 
Result so far: 173056.0
Deduct 2214 from 2437 and we're left with 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

Step 9:
2230 divided by 369 is 6 with a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 173056.6
Subtracting 2214 from 2230 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 10:
The number 369 fits into 160 0 times, leaving a remainder of 160.
The number 0 becomes the next digit in our result. 
Result so far: 173056.6
If we subtract 0 from 160, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 11:
If we divide 1600 by 369, we get 4 and a remainder of 124.
Write down 4 as next digit of the result. 
Result so far: 173056.604
Subtract 1476 from 1600 to get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Let's proceed to step 12:
369 can be fit into 1240 3 times, resulting in a remainder of 133.
Put 3 as the next digit of the answer. 
Result so far: 173056.6043
Deduct 1107 from 1240 and we're left with 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

On to step 13:
If we divide 1330 by 369, we get 3 and a remainder of 223.
Record the quotient 3 as the next digit in the result. 
Result so far: 173056.60433
Subtract 1107 from 1330 to get 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

After the division, we end up with 173056.60433 and a remainder of 0.000223.
