199803 divided by 31 
Let's see how many times 31 fits into 199803.

On to step 1:
If we divide 1 by 31, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 31

On to step 2:
If we divide 19 by 31, we get 0 and a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 19 after subtracting 0 from 19.
Bring next digit (9) of the dividend behind the 19 and repeat the process: 199 / 31

Advancing to step 3:
The number 31 fits into 199 6 times, leaving a remainder of 13.
The next digit of our result is 6. 
Result so far: 6.0
If we take 186 away from 199, we end up with 13.
Bring next digit (8) of the dividend behind the 13 and repeat the process: 138 / 31

Step 4:
31 goes into 138 4 times with a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 64.0
Subtract 124 from 138 to get 14.
Grab the next digit (0) from the dividend, add it to 14, then carry on: 140 / 31

Step 5:
The number 31 fits into 140 4 times, leaving a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 644.0
The remainder is 16 after subtracting 124 from 140.
Include the next digit (3) from the dividend after 16, then repeat: 163 / 31

Going ahead to step 6:
31 can be fit into 163 5 times, resulting in a remainder of 8.
The next digit of our result is 5. 
Result so far: 6445.0
Subtract 155 from 163 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 7:
The number 31 fits into 80 2 times, leaving a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 6445.2
Subtract 62 from 80 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 8:
When dividing 180 by 31, we get 5 with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 6445.25
Subtract 155 from 180 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 9:
250 divided by 31 is 8 with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 6445.258
If we subtract 248 from 250, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 10:
31 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 6445.258
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 11:
31 can be fit into 200 6 times, resulting in a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 6445.25806
Subtracting 186 from 200 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 12:
The number 31 fits into 140 4 times, leaving a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 6445.258064
Subtracting 124 from 140 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 13:
31 can be fit into 160 5 times, resulting in a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 6445.2580645
Deduct 155 from 160 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 14:
31 goes into 50 1 times with a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 6445.25806451
If we subtract 31 from 50, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

After the division, we end up with 6445.25806451 and a remainder of 1.9e-08.
