Let's divide 391089 by 36
Let's see how many times 36 fits into 391089.

Let's proceed to step 1:
3 divided by 36 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 36

Let's proceed to step 2:
If we divide 39 by 36, we get 1 and a remainder of 3.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 36 from 39 leaves us with 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 36

Step 3:
36 goes into 31 0 times with a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
The remainder is 31 after subtracting 0 from 31.
Fetch the next digit (0) from the dividend, attach it to 31 and continue: 310 / 36

Moving on to step 4:
The number 36 fits into 310 8 times, leaving a remainder of 22.
Write down 8 as next digit of the result. 
Result so far: 108.0
Subtract 288 from 310 to get 22.
Append the next digit (8) from the dividend to 22 and continue with: 228 / 36

On to step 5:
228 divided by 36 is 6 with a remainder of 12.
The next digit of our result is 6. 
Result so far: 1086.0
Subtracting 216 from 228 leaves us with 12.
Take the next digit (9) from the dividend and append it to 12, then repeat: 129 / 36

Advancing to step 6:
36 goes into 129 3 times with a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 10863.0
If we subtract 108 from 129, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 7:
If we divide 210 by 36, we get 5 and a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 10863.5
The remainder is 30 after subtracting 180 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 8:
The number 36 fits into 300 8 times, leaving a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 10863.58
Subtract 288 from 300 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 9:
If we divide 120 by 36, we get 3 and a remainder of 12.
Write down 3 as next digit of the result. 
Result so far: 10863.583
If we subtract 108 from 120, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 10:
When dividing 120 by 36, we get 3 with a remainder of 12.
Write down 3 as next digit of the result. 
Result so far: 10863.5833
Deduct 108 from 120 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 10863.5833, with a leftover of 0.00012.
