We look at the division of 19943531 by 336 
We're looking to find how many times 336 goes into 19943531.

On to step 1:
The number 336 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 336

Let's proceed to step 2:
336 goes into 19 0 times with a remainder of 19.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 19 leaves us with 19.
Fetch the next digit (9) from the dividend, attach it to 19 and continue: 199 / 336

Going ahead to step 3:
336 goes into 199 0 times with a remainder of 199.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 199, we get 199.
Take the next digit (4) from the dividend and append it to 199, then repeat: 1994 / 336

On to step 4:
336 can be fit into 1994 5 times, resulting in a remainder of 314.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtract 1680 from 1994 to get 314.
Grab the next digit (3) from the dividend, add it to 314, then carry on: 3143 / 336

On to step 5:
336 can be fit into 3143 9 times, resulting in a remainder of 119.
Record the quotient 9 as the next digit in the result. 
Result so far: 59.0
If we subtract 3024 from 3143, we get 119.
Fetch the next digit (5) from the dividend, attach it to 119 and continue: 1195 / 336

Advancing to step 6:
The number 336 fits into 1195 3 times, leaving a remainder of 187.
Write down 3 as next digit of the result. 
Result so far: 593.0
Subtract 1008 from 1195 to get 187.
Take the next digit (3) from the dividend and append it to 187, then repeat: 1873 / 336

Going ahead to step 7:
1873 divided by 336 is 5 with a remainder of 193.
Write down 5 as next digit of the result. 
Result so far: 5935.0
If we subtract 1680 from 1873, we get 193.
Include the next digit (1) from the dividend after 193, then repeat: 1931 / 336

Step 8:
336 can be fit into 1931 5 times, resulting in a remainder of 251.
Record the quotient 5 as the next digit in the result. 
Result so far: 59355.0
Deduct 1680 from 1931 and we're left with 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

Advancing to step 9:
2510 divided by 336 is 7 with a remainder of 158.
Record the quotient 7 as the next digit in the result. 
Result so far: 59355.7
If we subtract 2352 from 2510, we get 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Let's proceed to step 10:
The number 336 fits into 1580 4 times, leaving a remainder of 236.
Record the quotient 4 as the next digit in the result. 
Result so far: 59355.74
The remainder is 236 after subtracting 1344 from 1580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Step 11:
If we divide 2360 by 336, we get 7 and a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 59355.747
If we take 2352 away from 2360, we end up with 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 12:
If we divide 80 by 336, we get 0 and a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 59355.747
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 13:
336 can be fit into 800 2 times, resulting in a remainder of 128.
The next digit of our result is 2. 
Result so far: 59355.74702
Deduct 672 from 800 and we're left with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Moving on to step 14:
336 goes into 1280 3 times with a remainder of 272.
Write down 3 as next digit of the result. 
Result so far: 59355.747023
The remainder is 272 after subtracting 1008 from 1280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Advancing to step 15:
When dividing 2720 by 336, we get 8 with a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 59355.7470238
The remainder is 32 after subtracting 2688 from 2720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 16:
If we divide 320 by 336, we get 0 and a remainder of 320.
Use 0 as the next digit of our solution. 
Result so far: 59355.7470238
If we take 0 away from 320, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

The final result is 59355.7470238 with a remainder of 3.2e-07.
