We're dividing 48388433 by 646 
We want to figure out the number of times 48388433 can be divided by 646.

Moving on to step 1:
646 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 646

Advancing to step 2:
The number 646 fits into 48 0 times, leaving a remainder of 48.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 48 and we're left with 48.
Include the next digit (3) from the dividend after 48, then repeat: 483 / 646

Advancing to step 3:
If we divide 483 by 646, we get 0 and a remainder of 483.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 483, we get 483.
Take the next digit (8) from the dividend and append it to 483, then repeat: 4838 / 646

Step 4:
When dividing 4838 by 646, we get 7 with a remainder of 316.
The next digit of our result is 7. 
Result so far: 7.0
Subtracting 4522 from 4838 leaves us with 316.
Fetch the next digit (8) from the dividend, attach it to 316 and continue: 3168 / 646

Advancing to step 5:
646 goes into 3168 4 times with a remainder of 584.
Put 4 as the next digit of the answer. 
Result so far: 74.0
Subtracting 2584 from 3168 leaves us with 584.
Take the next digit (4) from the dividend and append it to 584, then repeat: 5844 / 646

Let's proceed to step 6:
5844 divided by 646 is 9 with a remainder of 30.
The number 9 becomes the next digit in our result. 
Result so far: 749.0
Subtract 5814 from 5844 to get 30.
Take the next digit (3) from the dividend and append it to 30, then repeat: 303 / 646

On to step 7:
When dividing 303 by 646, we get 0 with a remainder of 303.
Write down 0 as next digit of the result. 
Result so far: 7490.0
The remainder is 303 after subtracting 0 from 303.
Bring next digit (3) of the dividend behind the 303 and repeat the process: 3033 / 646

Advancing to step 8:
The number 646 fits into 3033 4 times, leaving a remainder of 449.
Write down 4 as next digit of the result. 
Result so far: 74904.0
Deduct 2584 from 3033 and we're left with 449.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4490, and continue the process.

Going ahead to step 9:
If we divide 4490 by 646, we get 6 and a remainder of 614.
The next digit of our result is 6. 
Result so far: 74904.6
If we subtract 3876 from 4490, we get 614.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6140, and continue the process.

Moving on to step 10:
646 goes into 6140 9 times with a remainder of 326.
Put 9 as the next digit of the answer. 
Result so far: 74904.69
Deduct 5814 from 6140 and we're left with 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Going ahead to step 11:
If we divide 3260 by 646, we get 5 and a remainder of 30.
The next digit of our result is 5. 
Result so far: 74904.695
The remainder is 30 after subtracting 3230 from 3260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 12:
646 goes into 300 0 times with a remainder of 300.
Put 0 as the next digit of the answer. 
Result so far: 74904.695
If we subtract 0 from 300, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

On to step 13:
3000 divided by 646 is 4 with a remainder of 416.
The next digit of our result is 4. 
Result so far: 74904.69504
If we subtract 2584 from 3000, we get 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Advancing to step 14:
When dividing 4160 by 646, we get 6 with a remainder of 284.
The next digit of our result is 6. 
Result so far: 74904.695046
The remainder is 284 after subtracting 3876 from 4160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Moving on to step 15:
The number 646 fits into 2840 4 times, leaving a remainder of 256.
The number 4 becomes the next digit in our result. 
Result so far: 74904.6950464
Subtracting 2584 from 2840 leaves us with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Step 16:
646 can be fit into 2560 3 times, resulting in a remainder of 622.
Use 3 as the next digit of our solution. 
Result so far: 74904.69504643
Subtract 1938 from 2560 to get 622.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6220, and continue the process.

The final outcome is 74904.69504643, with a leftover of 6.22e-07.
