63945655 divided by 422 
We want to figure out the number of times 63945655 can be divided by 422.

Step 1:
6 divided by 422 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 422

Let's proceed to step 2:
If we divide 63 by 422, we get 0 and a remainder of 63.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 63 leaves us with 63.
Grab the next digit (9) from the dividend, add it to 63, then carry on: 639 / 422

Advancing to step 3:
When dividing 639 by 422, we get 1 with a remainder of 217.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 422 from 639 to get 217.
Fetch the next digit (4) from the dividend, attach it to 217 and continue: 2174 / 422

Let's proceed to step 4:
2174 divided by 422 is 5 with a remainder of 64.
Write down 5 as next digit of the result. 
Result so far: 15.0
Deduct 2110 from 2174 and we're left with 64.
Bring next digit (5) of the dividend behind the 64 and repeat the process: 645 / 422

Let's proceed to step 5:
The number 422 fits into 645 1 times, leaving a remainder of 223.
The number 1 becomes the next digit in our result. 
Result so far: 151.0
If we take 422 away from 645, we end up with 223.
Fetch the next digit (6) from the dividend, attach it to 223 and continue: 2236 / 422

Let's proceed to step 6:
422 can be fit into 2236 5 times, resulting in a remainder of 126.
The next digit of our result is 5. 
Result so far: 1515.0
If we subtract 2110 from 2236, we get 126.
Fetch the next digit (5) from the dividend, attach it to 126 and continue: 1265 / 422

Step 7:
422 can be fit into 1265 2 times, resulting in a remainder of 421.
Record the quotient 2 as the next digit in the result. 
Result so far: 15152.0
Subtracting 844 from 1265 leaves us with 421.
Include the next digit (5) from the dividend after 421, then repeat: 4215 / 422

Step 8:
If we divide 4215 by 422, we get 9 and a remainder of 417.
Use 9 as the next digit of our solution. 
Result so far: 151529.0
The remainder is 417 after subtracting 3798 from 4215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4170, and continue the process.

On to step 9:
If we divide 4170 by 422, we get 9 and a remainder of 372.
The number 9 becomes the next digit in our result. 
Result so far: 151529.9
If we take 3798 away from 4170, we end up with 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Moving on to step 10:
The number 422 fits into 3720 8 times, leaving a remainder of 344.
Record the quotient 8 as the next digit in the result. 
Result so far: 151529.98
Deduct 3376 from 3720 and we're left with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Step 11:
3440 divided by 422 is 8 with a remainder of 64.
Use 8 as the next digit of our solution. 
Result so far: 151529.988
If we take 3376 away from 3440, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

After the division, we end up with 151529.988 and a remainder of 0.0064.
