Let's divide 48246936 by 646
We want to figure out the number of times 48246936 can be divided by 646.

Advancing to step 1:
The number 646 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 646

Going ahead to step 2:
When dividing 48 by 646, we get 0 with a remainder of 48.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 48 to get 48.
Take the next digit (2) from the dividend and append it to 48, then repeat: 482 / 646

On to step 3:
482 divided by 646 is 0 with a remainder of 482.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 482, we get 482.
Take the next digit (4) from the dividend and append it to 482, then repeat: 4824 / 646

Going ahead to step 4:
646 can be fit into 4824 7 times, resulting in a remainder of 302.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we subtract 4522 from 4824, we get 302.
Include the next digit (6) from the dividend after 302, then repeat: 3026 / 646

Step 5:
646 can be fit into 3026 4 times, resulting in a remainder of 442.
Use 4 as the next digit of our solution. 
Result so far: 74.0
Deduct 2584 from 3026 and we're left with 442.
Grab the next digit (9) from the dividend, add it to 442, then carry on: 4429 / 646

Step 6:
646 can be fit into 4429 6 times, resulting in a remainder of 553.
Use 6 as the next digit of our solution. 
Result so far: 746.0
If we take 3876 away from 4429, we end up with 553.
Fetch the next digit (3) from the dividend, attach it to 553 and continue: 5533 / 646

Moving on to step 7:
646 goes into 5533 8 times with a remainder of 365.
Use 8 as the next digit of our solution. 
Result so far: 7468.0
Deduct 5168 from 5533 and we're left with 365.
Bring next digit (6) of the dividend behind the 365 and repeat the process: 3656 / 646

Step 8:
If we divide 3656 by 646, we get 5 and a remainder of 426.
The number 5 becomes the next digit in our result. 
Result so far: 74685.0
Subtract 3230 from 3656 to get 426.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4260, and continue the process.

On to step 9:
646 can be fit into 4260 6 times, resulting in a remainder of 384.
Put 6 as the next digit of the answer. 
Result so far: 74685.6
The remainder is 384 after subtracting 3876 from 4260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Moving on to step 10:
3840 divided by 646 is 5 with a remainder of 610.
The next digit of our result is 5. 
Result so far: 74685.65
The remainder is 610 after subtracting 3230 from 3840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Moving on to step 11:
The number 646 fits into 6100 9 times, leaving a remainder of 286.
Use 9 as the next digit of our solution. 
Result so far: 74685.659
Deduct 5814 from 6100 and we're left with 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Step 12:
If we divide 2860 by 646, we get 4 and a remainder of 276.
Put 4 as the next digit of the answer. 
Result so far: 74685.6594
Deduct 2584 from 2860 and we're left with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Going ahead to step 13:
646 can be fit into 2760 4 times, resulting in a remainder of 176.
Record the quotient 4 as the next digit in the result. 
Result so far: 74685.65944
Subtracting 2584 from 2760 leaves us with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

The quotient of the division is 74685.65944, and the remainder is 0.000176.
