21407639 ÷ 693 
We're looking to find how many times 693 goes into 21407639.

Let's proceed to step 1:
If we divide 2 by 693, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 693

Step 2:
If we divide 21 by 693, we get 0 and a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Append the next digit (4) from the dividend to 21 and continue with: 214 / 693

Going ahead to step 3:
The number 693 fits into 214 0 times, leaving a remainder of 214.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 214 leaves us with 214.
Bring next digit (0) of the dividend behind the 214 and repeat the process: 2140 / 693

Step 4:
When dividing 2140 by 693, we get 3 with a remainder of 61.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 2079 from 2140 to get 61.
Grab the next digit (7) from the dividend, add it to 61, then carry on: 617 / 693

Moving on to step 5:
693 goes into 617 0 times with a remainder of 617.
Put 0 as the next digit of the answer. 
Result so far: 30.0
The remainder is 617 after subtracting 0 from 617.
Include the next digit (6) from the dividend after 617, then repeat: 6176 / 693

On to step 6:
6176 divided by 693 is 8 with a remainder of 632.
The number 8 becomes the next digit in our result. 
Result so far: 308.0
Subtracting 5544 from 6176 leaves us with 632.
Append the next digit (3) from the dividend to 632 and continue with: 6323 / 693

Advancing to step 7:
693 can be fit into 6323 9 times, resulting in a remainder of 86.
Put 9 as the next digit of the answer. 
Result so far: 3089.0
If we subtract 6237 from 6323, we get 86.
Take the next digit (9) from the dividend and append it to 86, then repeat: 869 / 693

Let's proceed to step 8:
If we divide 869 by 693, we get 1 and a remainder of 176.
The number 1 becomes the next digit in our result. 
Result so far: 30891.0
If we take 693 away from 869, we end up with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Going ahead to step 9:
If we divide 1760 by 693, we get 2 and a remainder of 374.
The number 2 becomes the next digit in our result. 
Result so far: 30891.2
Deduct 1386 from 1760 and we're left with 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

On to step 10:
If we divide 3740 by 693, we get 5 and a remainder of 275.
Use 5 as the next digit of our solution. 
Result so far: 30891.25
If we take 3465 away from 3740, we end up with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Step 11:
When dividing 2750 by 693, we get 3 with a remainder of 671.
Put 3 as the next digit of the answer. 
Result so far: 30891.253
Subtracting 2079 from 2750 leaves us with 671.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6710, and continue the process.

Let's proceed to step 12:
When dividing 6710 by 693, we get 9 with a remainder of 473.
Record the quotient 9 as the next digit in the result. 
Result so far: 30891.2539
Subtract 6237 from 6710 to get 473.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4730, and continue the process.

Step 13:
693 goes into 4730 6 times with a remainder of 572.
Write down 6 as next digit of the result. 
Result so far: 30891.25396
Deduct 4158 from 4730 and we're left with 572.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5720, and continue the process.

Advancing to step 14:
693 can be fit into 5720 8 times, resulting in a remainder of 176.
The next digit of our result is 8. 
Result so far: 30891.253968
Deduct 5544 from 5720 and we're left with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Going ahead to step 15:
The number 693 fits into 1760 2 times, leaving a remainder of 374.
Put 2 as the next digit of the answer. 
Result so far: 30891.2539682
Subtracting 1386 from 1760 leaves us with 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Moving on to step 16:
The number 693 fits into 3740 5 times, leaving a remainder of 275.
Put 5 as the next digit of the answer. 
Result so far: 30891.25396825
If we take 3465 away from 3740, we end up with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

The quotient of the division is 30891.25396825, and the remainder is 2.75e-07.
