Let's divide 46169292 by 646
We're looking to find how many times 646 goes into 46169292.

Step 1:
If we divide 4 by 646, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (6) from the dividend, add it to 4, then carry on: 46 / 646

On to step 2:
46 divided by 646 is 0 with a remainder of 46.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 46 after subtracting 0 from 46.
Append the next digit (1) from the dividend to 46 and continue with: 461 / 646

On to step 3:
646 goes into 461 0 times with a remainder of 461.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 461, we end up with 461.
Grab the next digit (6) from the dividend, add it to 461, then carry on: 4616 / 646

Let's proceed to step 4:
646 goes into 4616 7 times with a remainder of 94.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 4522 from 4616 and we're left with 94.
Include the next digit (9) from the dividend after 94, then repeat: 949 / 646

On to step 5:
646 can be fit into 949 1 times, resulting in a remainder of 303.
Use 1 as the next digit of our solution. 
Result so far: 71.0
If we subtract 646 from 949, we get 303.
Take the next digit (2) from the dividend and append it to 303, then repeat: 3032 / 646

Moving on to step 6:
646 goes into 3032 4 times with a remainder of 448.
Use 4 as the next digit of our solution. 
Result so far: 714.0
If we take 2584 away from 3032, we end up with 448.
Fetch the next digit (9) from the dividend, attach it to 448 and continue: 4489 / 646

Moving on to step 7:
646 can be fit into 4489 6 times, resulting in a remainder of 613.
Use 6 as the next digit of our solution. 
Result so far: 7146.0
Subtracting 3876 from 4489 leaves us with 613.
Take the next digit (2) from the dividend and append it to 613, then repeat: 6132 / 646

Advancing to step 8:
646 can be fit into 6132 9 times, resulting in a remainder of 318.
Use 9 as the next digit of our solution. 
Result so far: 71469.0
If we take 5814 away from 6132, we end up with 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

On to step 9:
When dividing 3180 by 646, we get 4 with a remainder of 596.
The next digit of our result is 4. 
Result so far: 71469.4
Deduct 2584 from 3180 and we're left with 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

Step 10:
646 can be fit into 5960 9 times, resulting in a remainder of 146.
The number 9 becomes the next digit in our result. 
Result so far: 71469.49
The remainder is 146 after subtracting 5814 from 5960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Going ahead to step 11:
The number 646 fits into 1460 2 times, leaving a remainder of 168.
Use 2 as the next digit of our solution. 
Result so far: 71469.492
If we take 1292 away from 1460, we end up with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Going ahead to step 12:
1680 divided by 646 is 2 with a remainder of 388.
Write down 2 as next digit of the result. 
Result so far: 71469.4922
Subtract 1292 from 1680 to get 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

The final outcome is 71469.4922, with a leftover of 0.00388.
