We're dividing 63549933 by 861 
Our goal is to divide 63549933 by 861.

Advancing to step 1:
6 divided by 861 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 861

Advancing to step 2:
861 goes into 63 0 times with a remainder of 63.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 63 after subtracting 0 from 63.
Fetch the next digit (5) from the dividend, attach it to 63 and continue: 635 / 861

Advancing to step 3:
When dividing 635 by 861, we get 0 with a remainder of 635.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 635, we end up with 635.
Take the next digit (4) from the dividend and append it to 635, then repeat: 6354 / 861

Going ahead to step 4:
If we divide 6354 by 861, we get 7 and a remainder of 327.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we take 6027 away from 6354, we end up with 327.
Bring next digit (9) of the dividend behind the 327 and repeat the process: 3279 / 861

On to step 5:
861 goes into 3279 3 times with a remainder of 696.
Use 3 as the next digit of our solution. 
Result so far: 73.0
If we take 2583 away from 3279, we end up with 696.
Bring next digit (9) of the dividend behind the 696 and repeat the process: 6969 / 861

Advancing to step 6:
The number 861 fits into 6969 8 times, leaving a remainder of 81.
Record the quotient 8 as the next digit in the result. 
Result so far: 738.0
If we take 6888 away from 6969, we end up with 81.
Take the next digit (3) from the dividend and append it to 81, then repeat: 813 / 861

Step 7:
861 can be fit into 813 0 times, resulting in a remainder of 813.
Record the quotient 0 as the next digit in the result. 
Result so far: 7380.0
Subtracting 0 from 813 leaves us with 813.
Append the next digit (3) from the dividend to 813 and continue with: 8133 / 861

Moving on to step 8:
When dividing 8133 by 861, we get 9 with a remainder of 384.
Write down 9 as next digit of the result. 
Result so far: 73809.0
If we take 7749 away from 8133, we end up with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Let's proceed to step 9:
861 goes into 3840 4 times with a remainder of 396.
Use 4 as the next digit of our solution. 
Result so far: 73809.4
If we subtract 3444 from 3840, we get 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Let's proceed to step 10:
3960 divided by 861 is 4 with a remainder of 516.
The number 4 becomes the next digit in our result. 
Result so far: 73809.44
Deduct 3444 from 3960 and we're left with 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

The quotient of the division is 73809.44, and the remainder is 0.516.
