63703222 divided by 869 
Our goal is to divide 63703222 by 869.

Going ahead to step 1:
The number 869 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 869

Advancing to step 2:
869 goes into 63 0 times with a remainder of 63.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 63 after subtracting 0 from 63.
Take the next digit (7) from the dividend and append it to 63, then repeat: 637 / 869

Let's proceed to step 3:
If we divide 637 by 869, we get 0 and a remainder of 637.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 637 leaves us with 637.
Include the next digit (0) from the dividend after 637, then repeat: 6370 / 869

Step 4:
If we divide 6370 by 869, we get 7 and a remainder of 287.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtracting 6083 from 6370 leaves us with 287.
Fetch the next digit (3) from the dividend, attach it to 287 and continue: 2873 / 869

Step 5:
2873 divided by 869 is 3 with a remainder of 266.
Put 3 as the next digit of the answer. 
Result so far: 73.0
Deduct 2607 from 2873 and we're left with 266.
Take the next digit (2) from the dividend and append it to 266, then repeat: 2662 / 869

Let's proceed to step 6:
If we divide 2662 by 869, we get 3 and a remainder of 55.
Put 3 as the next digit of the answer. 
Result so far: 733.0
The remainder is 55 after subtracting 2607 from 2662.
Take the next digit (2) from the dividend and append it to 55, then repeat: 552 / 869

On to step 7:
If we divide 552 by 869, we get 0 and a remainder of 552.
The next digit of our result is 0. 
Result so far: 7330.0
Subtract 0 from 552 to get 552.
Take the next digit (2) from the dividend and append it to 552, then repeat: 5522 / 869

Step 8:
If we divide 5522 by 869, we get 6 and a remainder of 308.
Put 6 as the next digit of the answer. 
Result so far: 73306.0
Subtracting 5214 from 5522 leaves us with 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Going ahead to step 9:
If we divide 3080 by 869, we get 3 and a remainder of 473.
The number 3 becomes the next digit in our result. 
Result so far: 73306.3
If we subtract 2607 from 3080, we get 473.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4730, and continue the process.

Advancing to step 10:
If we divide 4730 by 869, we get 5 and a remainder of 385.
The next digit of our result is 5. 
Result so far: 73306.35
Deduct 4345 from 4730 and we're left with 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Moving on to step 11:
869 goes into 3850 4 times with a remainder of 374.
Put 4 as the next digit of the answer. 
Result so far: 73306.354
If we take 3476 away from 3850, we end up with 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

On to step 12:
3740 divided by 869 is 4 with a remainder of 264.
Use 4 as the next digit of our solution. 
Result so far: 73306.3544
Deduct 3476 from 3740 and we're left with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

The final result is 73306.3544 with a remainder of 0.00264.
