939439 ÷ 91 
Our goal is to divide 939439 by 91.

On to step 1:
91 can be fit into 9 0 times, resulting in a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Take the next digit (3) from the dividend and append it to 9, then repeat: 93 / 91

Moving on to step 2:
If we divide 93 by 91, we get 1 and a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 91 from 93 and we're left with 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 91

Advancing to step 3:
91 goes into 29 0 times with a remainder of 29.
The next digit of our result is 0. 
Result so far: 10.0
If we take 0 away from 29, we end up with 29.
Take the next digit (4) from the dividend and append it to 29, then repeat: 294 / 91

Advancing to step 4:
294 divided by 91 is 3 with a remainder of 21.
The next digit of our result is 3. 
Result so far: 103.0
Deduct 273 from 294 and we're left with 21.
Grab the next digit (3) from the dividend, add it to 21, then carry on: 213 / 91

Step 5:
91 goes into 213 2 times with a remainder of 31.
The next digit of our result is 2. 
Result so far: 1032.0
The remainder is 31 after subtracting 182 from 213.
Fetch the next digit (9) from the dividend, attach it to 31 and continue: 319 / 91

Going ahead to step 6:
91 can be fit into 319 3 times, resulting in a remainder of 46.
The number 3 becomes the next digit in our result. 
Result so far: 10323.0
The remainder is 46 after subtracting 273 from 319.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 7:
460 divided by 91 is 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 10323.5
Subtract 455 from 460 to get 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:
91 can be fit into 50 0 times, resulting in a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 10323.5
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 9:
The number 91 fits into 500 5 times, leaving a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 10323.505
Deduct 455 from 500 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 10:
The number 91 fits into 450 4 times, leaving a remainder of 86.
Write down 4 as next digit of the result. 
Result so far: 10323.5054
Deduct 364 from 450 and we're left with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

On to step 11:
The number 91 fits into 860 9 times, leaving a remainder of 41.
The number 9 becomes the next digit in our result. 
Result so far: 10323.50549
If we subtract 819 from 860, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 12:
91 goes into 410 4 times with a remainder of 46.
Use 4 as the next digit of our solution. 
Result so far: 10323.505494
Subtract 364 from 410 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 13:
The number 91 fits into 460 5 times, leaving a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 10323.5054945
Deduct 455 from 460 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:
If we divide 50 by 91, we get 0 and a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 10323.5054945
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Our division results in 10323.5054945 with a remaining 5e-08.
