We divide 66446210 by 1
We want to divide 66446210 by 1.

On to step 1:
The number 1 fits into 6 6 times, leaving a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we subtract 6 from 6, we get 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 1

Going ahead to step 2:
6 divided by 1 is 6 with a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 66.0
Subtract 6 from 6 to get 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 1

On to step 3:
If we divide 4 by 1, we get 4 and a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 664.0
If we take 4 away from 4, we end up with 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 1

Advancing to step 4:
If we divide 4 by 1, we get 4 and a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 6644.0
If we take 4 away from 4, we end up with 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 1

Let's proceed to step 5:
The number 1 fits into 6 6 times, leaving a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 66446.0
If we take 6 away from 6, we end up with 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 1

On to step 6:
2 divided by 1 is 2 with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 664462.0
Subtracting 2 from 2 leaves us with 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 1

Let's proceed to step 7:
When dividing 1 by 1, we get 1 with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 6644621.0
The remainder is 0 after subtracting 1 from 1.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 1

On to step 8:
0 divided by 1 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 66446210.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
When dividing 0 by 1, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 66446210.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
When dividing 0 by 1, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 66446210.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 66446210.0 with a remainder of 0.0.
