Let's divide 82946199 by 646
We're looking to find how many times 646 goes into 82946199.

On to step 1:
646 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (2) of the dividend behind the 8 and repeat the process: 82 / 646

Advancing to step 2:
646 can be fit into 82 0 times, resulting in a remainder of 82.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 82, we end up with 82.
Bring next digit (9) of the dividend behind the 82 and repeat the process: 829 / 646

Going ahead to step 3:
646 can be fit into 829 1 times, resulting in a remainder of 183.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 646 from 829 and we're left with 183.
Grab the next digit (4) from the dividend, add it to 183, then carry on: 1834 / 646

On to step 4:
The number 646 fits into 1834 2 times, leaving a remainder of 542.
The next digit of our result is 2. 
Result so far: 12.0
If we take 1292 away from 1834, we end up with 542.
Append the next digit (6) from the dividend to 542 and continue with: 5426 / 646

Moving on to step 5:
5426 divided by 646 is 8 with a remainder of 258.
The number 8 becomes the next digit in our result. 
Result so far: 128.0
Subtract 5168 from 5426 to get 258.
Grab the next digit (1) from the dividend, add it to 258, then carry on: 2581 / 646

Let's proceed to step 6:
646 can be fit into 2581 3 times, resulting in a remainder of 643.
Use 3 as the next digit of our solution. 
Result so far: 1283.0
The remainder is 643 after subtracting 1938 from 2581.
Include the next digit (9) from the dividend after 643, then repeat: 6439 / 646

Step 7:
646 goes into 6439 9 times with a remainder of 625.
Put 9 as the next digit of the answer. 
Result so far: 12839.0
Subtracting 5814 from 6439 leaves us with 625.
Include the next digit (9) from the dividend after 625, then repeat: 6259 / 646

Moving on to step 8:
646 goes into 6259 9 times with a remainder of 445.
The next digit of our result is 9. 
Result so far: 128399.0
If we take 5814 away from 6259, we end up with 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

Step 9:
646 can be fit into 4450 6 times, resulting in a remainder of 574.
Record the quotient 6 as the next digit in the result. 
Result so far: 128399.6
Subtracting 3876 from 4450 leaves us with 574.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5740, and continue the process.

Advancing to step 10:
646 goes into 5740 8 times with a remainder of 572.
The number 8 becomes the next digit in our result. 
Result so far: 128399.68
Deduct 5168 from 5740 and we're left with 572.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5720, and continue the process.

Let's proceed to step 11:
When dividing 5720 by 646, we get 8 with a remainder of 552.
Use 8 as the next digit of our solution. 
Result so far: 128399.688
Subtract 5168 from 5720 to get 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

The final outcome is 128399.688, with a leftover of 0.0552.
