Let's divide 203243 by 646
We want to figure out the number of times 203243 can be divided by 646.

Advancing to step 1:
If we divide 2 by 646, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 646

Moving on to step 2:
The number 646 fits into 20 0 times, leaving a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 20 leaves us with 20.
Fetch the next digit (3) from the dividend, attach it to 20 and continue: 203 / 646

Let's proceed to step 3:
646 can be fit into 203 0 times, resulting in a remainder of 203.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 203, we end up with 203.
Grab the next digit (2) from the dividend, add it to 203, then carry on: 2032 / 646

Advancing to step 4:
When dividing 2032 by 646, we get 3 with a remainder of 94.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 1938 away from 2032, we end up with 94.
Append the next digit (4) from the dividend to 94 and continue with: 944 / 646

Advancing to step 5:
646 goes into 944 1 times with a remainder of 298.
Use 1 as the next digit of our solution. 
Result so far: 31.0
If we take 646 away from 944, we end up with 298.
Grab the next digit (3) from the dividend, add it to 298, then carry on: 2983 / 646

Moving on to step 6:
646 can be fit into 2983 4 times, resulting in a remainder of 399.
The number 4 becomes the next digit in our result. 
Result so far: 314.0
If we take 2584 away from 2983, we end up with 399.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3990, and continue the process.

Moving on to step 7:
When dividing 3990 by 646, we get 6 with a remainder of 114.
Record the quotient 6 as the next digit in the result. 
Result so far: 314.6
If we take 3876 away from 3990, we end up with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

On to step 8:
If we divide 1140 by 646, we get 1 and a remainder of 494.
The number 1 becomes the next digit in our result. 
Result so far: 314.61
The remainder is 494 after subtracting 646 from 1140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

Going ahead to step 9:
646 goes into 4940 7 times with a remainder of 418.
Record the quotient 7 as the next digit in the result. 
Result so far: 314.617
Deduct 4522 from 4940 and we're left with 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Step 10:
When dividing 4180 by 646, we get 6 with a remainder of 304.
The number 6 becomes the next digit in our result. 
Result so far: 314.6176
If we take 3876 away from 4180, we end up with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Step 11:
When dividing 3040 by 646, we get 4 with a remainder of 456.
Use 4 as the next digit of our solution. 
Result so far: 314.61764
Subtract 2584 from 3040 to get 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Advancing to step 12:
If we divide 4560 by 646, we get 7 and a remainder of 38.
The next digit of our result is 7. 
Result so far: 314.617647
If we subtract 4522 from 4560, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 13:
The number 646 fits into 380 0 times, leaving a remainder of 380.
Use 0 as the next digit of our solution. 
Result so far: 314.617647
Subtracting 0 from 380 leaves us with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Moving on to step 14:
3800 divided by 646 is 5 with a remainder of 570.
Put 5 as the next digit of the answer. 
Result so far: 314.61764705
Deduct 3230 from 3800 and we're left with 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

The quotient of the division is 314.61764705, and the remainder is 5.7e-07.
