21681015 divided by 935 
Let's see how many times 935 fits into 21681015.

Step 1:
When dividing 2 by 935, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 935

Step 2:
The number 935 fits into 21 0 times, leaving a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Take the next digit (6) from the dividend and append it to 21, then repeat: 216 / 935

Let's proceed to step 3:
When dividing 216 by 935, we get 0 with a remainder of 216.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 216 leaves us with 216.
Grab the next digit (8) from the dividend, add it to 216, then carry on: 2168 / 935

Step 4:
If we divide 2168 by 935, we get 2 and a remainder of 298.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 1870 from 2168 and we're left with 298.
Take the next digit (1) from the dividend and append it to 298, then repeat: 2981 / 935

Let's proceed to step 5:
The number 935 fits into 2981 3 times, leaving a remainder of 176.
Put 3 as the next digit of the answer. 
Result so far: 23.0
The remainder is 176 after subtracting 2805 from 2981.
Append the next digit (0) from the dividend to 176 and continue with: 1760 / 935

Going ahead to step 6:
The number 935 fits into 1760 1 times, leaving a remainder of 825.
Put 1 as the next digit of the answer. 
Result so far: 231.0
The remainder is 825 after subtracting 935 from 1760.
Include the next digit (1) from the dividend after 825, then repeat: 8251 / 935

On to step 7:
8251 divided by 935 is 8 with a remainder of 771.
Record the quotient 8 as the next digit in the result. 
Result so far: 2318.0
Deduct 7480 from 8251 and we're left with 771.
Bring next digit (5) of the dividend behind the 771 and repeat the process: 7715 / 935

Let's proceed to step 8:
935 can be fit into 7715 8 times, resulting in a remainder of 235.
Put 8 as the next digit of the answer. 
Result so far: 23188.0
The remainder is 235 after subtracting 7480 from 7715.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

On to step 9:
935 goes into 2350 2 times with a remainder of 480.
Put 2 as the next digit of the answer. 
Result so far: 23188.2
Subtracting 1870 from 2350 leaves us with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Going ahead to step 10:
4800 divided by 935 is 5 with a remainder of 125.
Write down 5 as next digit of the result. 
Result so far: 23188.25
Deduct 4675 from 4800 and we're left with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Moving on to step 11:
The number 935 fits into 1250 1 times, leaving a remainder of 315.
The next digit of our result is 1. 
Result so far: 23188.251
Subtracting 935 from 1250 leaves us with 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Going ahead to step 12:
The number 935 fits into 3150 3 times, leaving a remainder of 345.
Write down 3 as next digit of the result. 
Result so far: 23188.2513
The remainder is 345 after subtracting 2805 from 3150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

Let's proceed to step 13:
The number 935 fits into 3450 3 times, leaving a remainder of 645.
Record the quotient 3 as the next digit in the result. 
Result so far: 23188.25133
If we take 2805 away from 3450, we end up with 645.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6450, and continue the process.

The final outcome is 23188.25133, with a leftover of 0.000645.
