21696137 ÷ 287 
We want to divide 21696137 by 287.

Advancing to step 1:
When dividing 2 by 287, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 287

Going ahead to step 2:
287 can be fit into 21 0 times, resulting in a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Include the next digit (6) from the dividend after 21, then repeat: 216 / 287

Step 3:
287 can be fit into 216 0 times, resulting in a remainder of 216.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 216, we end up with 216.
Include the next digit (9) from the dividend after 216, then repeat: 2169 / 287

On to step 4:
287 goes into 2169 7 times with a remainder of 160.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtracting 2009 from 2169 leaves us with 160.
Bring next digit (6) of the dividend behind the 160 and repeat the process: 1606 / 287

On to step 5:
287 can be fit into 1606 5 times, resulting in a remainder of 171.
The number 5 becomes the next digit in our result. 
Result so far: 75.0
Subtract 1435 from 1606 to get 171.
Include the next digit (1) from the dividend after 171, then repeat: 1711 / 287

Advancing to step 6:
If we divide 1711 by 287, we get 5 and a remainder of 276.
Write down 5 as next digit of the result. 
Result so far: 755.0
Subtracting 1435 from 1711 leaves us with 276.
Fetch the next digit (3) from the dividend, attach it to 276 and continue: 2763 / 287

On to step 7:
When dividing 2763 by 287, we get 9 with a remainder of 180.
The number 9 becomes the next digit in our result. 
Result so far: 7559.0
Deduct 2583 from 2763 and we're left with 180.
Bring next digit (7) of the dividend behind the 180 and repeat the process: 1807 / 287

Moving on to step 8:
The number 287 fits into 1807 6 times, leaving a remainder of 85.
The next digit of our result is 6. 
Result so far: 75596.0
If we take 1722 away from 1807, we end up with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Moving on to step 9:
850 divided by 287 is 2 with a remainder of 276.
Record the quotient 2 as the next digit in the result. 
Result so far: 75596.2
If we take 574 away from 850, we end up with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Step 10:
2760 divided by 287 is 9 with a remainder of 177.
Put 9 as the next digit of the answer. 
Result so far: 75596.29
The remainder is 177 after subtracting 2583 from 2760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

Let's proceed to step 11:
1770 divided by 287 is 6 with a remainder of 48.
Use 6 as the next digit of our solution. 
Result so far: 75596.296
Subtract 1722 from 1770 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 12:
287 can be fit into 480 1 times, resulting in a remainder of 193.
The next digit of our result is 1. 
Result so far: 75596.2961
If we subtract 287 from 480, we get 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

Advancing to step 13:
287 goes into 1930 6 times with a remainder of 208.
The number 6 becomes the next digit in our result. 
Result so far: 75596.29616
Deduct 1722 from 1930 and we're left with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

On to step 14:
287 goes into 2080 7 times with a remainder of 71.
Write down 7 as next digit of the result. 
Result so far: 75596.296167
If we take 2009 away from 2080, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

On to step 15:
287 can be fit into 710 2 times, resulting in a remainder of 136.
The next digit of our result is 2. 
Result so far: 75596.2961672
If we subtract 574 from 710, we get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Let's proceed to step 16:
1360 divided by 287 is 4 with a remainder of 212.
Write down 4 as next digit of the result. 
Result so far: 75596.29616724
Deduct 1148 from 1360 and we're left with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

The final result is 75596.29616724 with a remainder of 2.12e-07.
