543953 ÷ 39 
We want to figure out the number of times 543953 can be divided by 39.

On to step 1:
The number 39 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 39

On to step 2:
39 goes into 54 1 times with a remainder of 15.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 39 from 54 and we're left with 15.
Grab the next digit (3) from the dividend, add it to 15, then carry on: 153 / 39

Moving on to step 3:
153 divided by 39 is 3 with a remainder of 36.
Write down 3 as next digit of the result. 
Result so far: 13.0
If we take 117 away from 153, we end up with 36.
Bring next digit (9) of the dividend behind the 36 and repeat the process: 369 / 39

Going ahead to step 4:
The number 39 fits into 369 9 times, leaving a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 139.0
Deduct 351 from 369 and we're left with 18.
Append the next digit (5) from the dividend to 18 and continue with: 185 / 39

Step 5:
39 can be fit into 185 4 times, resulting in a remainder of 29.
The number 4 becomes the next digit in our result. 
Result so far: 1394.0
If we subtract 156 from 185, we get 29.
Include the next digit (3) from the dividend after 29, then repeat: 293 / 39

On to step 6:
The number 39 fits into 293 7 times, leaving a remainder of 20.
Write down 7 as next digit of the result. 
Result so far: 13947.0
Subtract 273 from 293 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 7:
39 can be fit into 200 5 times, resulting in a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 13947.5
If we take 195 away from 200, we end up 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.

Step 8:
39 goes into 50 1 times with a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 13947.51
The remainder is 11 after subtracting 39 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 9:
The number 39 fits into 110 2 times, leaving a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 13947.512
If we take 78 away from 110, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 10:
If we divide 320 by 39, we get 8 and a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 13947.5128
Subtract 312 from 320 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.

Moving on to step 11:
The number 39 fits into 80 2 times, leaving a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 13947.51282
The remainder is 2 after subtracting 78 from 80.
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 12:
39 goes into 20 0 times with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 13947.51282
Deduct 0 from 20 and we're left 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.

Moving on to step 13:
200 divided by 39 is 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 13947.5128205
Deduct 195 from 200 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.

On to step 14:
39 goes into 50 1 times with a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 13947.51282051
Subtract 39 from 50 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

The quotient of the division is 13947.51282051, and the remainder is 1.1e-08.
