We look at the division of 45681297 by 3 
We want to figure out the number of times 45681297 can be divided by 3.

On to step 1:
3 goes into 4 1 times with a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 3 from 4, we get 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 3

Going ahead to step 2:
The number 3 fits into 15 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 15.0
If we take 15 away from 15, we end up with 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 3

Step 3:
6 divided by 3 is 2 with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 152.0
Deduct 6 from 6 and we're left with 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 3

Going ahead to step 4:
If we divide 8 by 3, we get 2 and a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 1522.0
Subtract 6 from 8 to get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 3

Going ahead to step 5:
The number 3 fits into 21 7 times, leaving a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 15227.0
If we take 21 away from 21, we end up with 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 3

Let's proceed to step 6:
3 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 152270.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 3

On to step 7:
If we divide 29 by 3, we get 9 and a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 1522709.0
If we subtract 27 from 29, we get 2.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 3

On to step 8:
The number 3 fits into 27 9 times, leaving a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 15227099.0
If we subtract 27 from 27, 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.

Let's proceed to step 9:
The number 3 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 15227099.0
Subtract 0 from 0 to 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.

Going ahead to step 10:
3 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 15227099.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 15227099.0 and a remainder of 0.0.
