We divide 21701593 by 910
We want to figure out the number of times 21701593 can be divided by 910.

Step 1:
If we divide 2 by 910, we get 0 and 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.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 910

Going ahead to step 2:
910 goes into 21 0 times with a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Include the next digit (7) from the dividend after 21, then repeat: 217 / 910

Step 3:
If we divide 217 by 910, we get 0 and a remainder of 217.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 217 leaves us with 217.
Append the next digit (0) from the dividend to 217 and continue with: 2170 / 910

Moving on to step 4:
910 can be fit into 2170 2 times, resulting in a remainder of 350.
The next digit of our result is 2. 
Result so far: 2.0
If we take 1820 away from 2170, we end up with 350.
Append the next digit (1) from the dividend to 350 and continue with: 3501 / 910

On to step 5:
If we divide 3501 by 910, we get 3 and a remainder of 771.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
The remainder is 771 after subtracting 2730 from 3501.
Take the next digit (5) from the dividend and append it to 771, then repeat: 7715 / 910

Advancing to step 6:
If we divide 7715 by 910, we get 8 and a remainder of 435.
Use 8 as the next digit of our solution. 
Result so far: 238.0
If we subtract 7280 from 7715, we get 435.
Fetch the next digit (9) from the dividend, attach it to 435 and continue: 4359 / 910

Advancing to step 7:
If we divide 4359 by 910, we get 4 and a remainder of 719.
The number 4 becomes the next digit in our result. 
Result so far: 2384.0
If we take 3640 away from 4359, we end up with 719.
Bring next digit (3) of the dividend behind the 719 and repeat the process: 7193 / 910

Let's proceed to step 8:
910 can be fit into 7193 7 times, resulting in a remainder of 823.
Put 7 as the next digit of the answer. 
Result so far: 23847.0
Deduct 6370 from 7193 and we're left with 823.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8230, and continue the process.

Step 9:
910 goes into 8230 9 times with a remainder of 40.
Use 9 as the next digit of our solution. 
Result so far: 23847.9
Deduct 8190 from 8230 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 10:
910 goes into 400 0 times with a remainder of 400.
Write down 0 as next digit of the result. 
Result so far: 23847.9
Deduct 0 from 400 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Going ahead to step 11:
If we divide 4000 by 910, we get 4 and a remainder of 360.
The number 4 becomes the next digit in our result. 
Result so far: 23847.904
If we subtract 3640 from 4000, we get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

On to step 12:
910 can be fit into 3600 3 times, resulting in a remainder of 870.
The next digit of our result is 3. 
Result so far: 23847.9043
Deduct 2730 from 3600 and we're left with 870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8700, and continue the process.

Moving on to step 13:
The number 910 fits into 8700 9 times, leaving a remainder of 510.
The next digit of our result is 9. 
Result so far: 23847.90439
Deduct 8190 from 8700 and we're left with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Step 14:
When dividing 5100 by 910, we get 5 with a remainder of 550.
Put 5 as the next digit of the answer. 
Result so far: 23847.904395
Deduct 4550 from 5100 and we're left with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Moving on to step 15:
The number 910 fits into 5500 6 times, leaving a remainder of 40.
Use 6 as the next digit of our solution. 
Result so far: 23847.9043956
The remainder is 40 after subtracting 5460 from 5500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 16:
When dividing 400 by 910, we get 0 with a remainder of 400.
Put 0 as the next digit of the answer. 
Result so far: 23847.9043956
Subtracting 0 from 400 leaves us with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The quotient of the division is 23847.9043956, and the remainder is 4e-07.
