We're dividing 63834821 by 955 
We want to figure out the number of times 63834821 can be divided by 955.

Advancing to step 1:
The number 955 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
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 / 955

On to step 2:
The number 955 fits into 63 0 times, leaving a remainder of 63.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 63 and we're left with 63.
Append the next digit (8) from the dividend to 63 and continue with: 638 / 955

Moving on to step 3:
The number 955 fits into 638 0 times, leaving a remainder of 638.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 638 and we're left with 638.
Include the next digit (3) from the dividend after 638, then repeat: 6383 / 955

On to step 4:
If we divide 6383 by 955, we get 6 and a remainder of 653.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we subtract 5730 from 6383, we get 653.
Include the next digit (4) from the dividend after 653, then repeat: 6534 / 955

Let's proceed to step 5:
The number 955 fits into 6534 6 times, leaving a remainder of 804.
Put 6 as the next digit of the answer. 
Result so far: 66.0
Subtract 5730 from 6534 to get 804.
Fetch the next digit (8) from the dividend, attach it to 804 and continue: 8048 / 955

Step 6:
955 can be fit into 8048 8 times, resulting in a remainder of 408.
The number 8 becomes the next digit in our result. 
Result so far: 668.0
If we take 7640 away from 8048, we end up with 408.
Include the next digit (2) from the dividend after 408, then repeat: 4082 / 955

On to step 7:
When dividing 4082 by 955, we get 4 with a remainder of 262.
Write down 4 as next digit of the result. 
Result so far: 6684.0
The remainder is 262 after subtracting 3820 from 4082.
Take the next digit (1) from the dividend and append it to 262, then repeat: 2621 / 955

Advancing to step 8:
955 can be fit into 2621 2 times, resulting in a remainder of 711.
The number 2 becomes the next digit in our result. 
Result so far: 66842.0
Subtracting 1910 from 2621 leaves us with 711.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7110, and continue the process.

Moving on to step 9:
955 can be fit into 7110 7 times, resulting in a remainder of 425.
Put 7 as the next digit of the answer. 
Result so far: 66842.7
If we take 6685 away from 7110, we end up with 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Advancing to step 10:
4250 divided by 955 is 4 with a remainder of 430.
The next digit of our result is 4. 
Result so far: 66842.74
If we subtract 3820 from 4250, we get 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

On to step 11:
When dividing 4300 by 955, we get 4 with a remainder of 480.
The next digit of our result is 4. 
Result so far: 66842.744
Deduct 3820 from 4300 and we're left with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

The final outcome is 66842.744, with a leftover of 0.048.
