19749938 ÷ 689 
We're looking to find how many times 689 goes into 19749938.

Let's proceed to step 1:
1 divided by 689 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 689

On to step 2:
When dividing 19 by 689, we get 0 with a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 19 leaves us with 19.
Bring next digit (7) of the dividend behind the 19 and repeat the process: 197 / 689

Advancing to step 3:
689 goes into 197 0 times with a remainder of 197.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 197 and we're left with 197.
Grab the next digit (4) from the dividend, add it to 197, then carry on: 1974 / 689

Advancing to step 4:
689 can be fit into 1974 2 times, resulting in a remainder of 596.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 1378 from 1974 leaves us with 596.
Fetch the next digit (9) from the dividend, attach it to 596 and continue: 5969 / 689

Advancing to step 5:
If we divide 5969 by 689, we get 8 and a remainder of 457.
Write down 8 as next digit of the result. 
Result so far: 28.0
Subtract 5512 from 5969 to get 457.
Bring next digit (9) of the dividend behind the 457 and repeat the process: 4579 / 689

Advancing to step 6:
689 goes into 4579 6 times with a remainder of 445.
The number 6 becomes the next digit in our result. 
Result so far: 286.0
If we take 4134 away from 4579, we end up with 445.
Fetch the next digit (3) from the dividend, attach it to 445 and continue: 4453 / 689

Step 7:
689 can be fit into 4453 6 times, resulting in a remainder of 319.
Use 6 as the next digit of our solution. 
Result so far: 2866.0
Deduct 4134 from 4453 and we're left with 319.
Grab the next digit (8) from the dividend, add it to 319, then carry on: 3198 / 689

Going ahead to step 8:
When dividing 3198 by 689, we get 4 with a remainder of 442.
The number 4 becomes the next digit in our result. 
Result so far: 28664.0
The remainder is 442 after subtracting 2756 from 3198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

Moving on to step 9:
689 goes into 4420 6 times with a remainder of 286.
Put 6 as the next digit of the answer. 
Result so far: 28664.6
The remainder is 286 after subtracting 4134 from 4420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Going ahead to step 10:
If we divide 2860 by 689, we get 4 and a remainder of 104.
Put 4 as the next digit of the answer. 
Result so far: 28664.64
If we take 2756 away from 2860, we end up with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Going ahead to step 11:
When dividing 1040 by 689, we get 1 with a remainder of 351.
Write down 1 as next digit of the result. 
Result so far: 28664.641
If we take 689 away from 1040, we end up with 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

Let's proceed to step 12:
689 can be fit into 3510 5 times, resulting in a remainder of 65.
Use 5 as the next digit of our solution. 
Result so far: 28664.6415
If we subtract 3445 from 3510, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 13:
The number 689 fits into 650 0 times, leaving a remainder of 650.
The next digit of our result is 0. 
Result so far: 28664.6415
If we take 0 away from 650, we end up with 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Moving on to step 14:
The number 689 fits into 6500 9 times, leaving a remainder of 299.
The number 9 becomes the next digit in our result. 
Result so far: 28664.641509
Subtracting 6201 from 6500 leaves us with 299.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

Step 15:
When dividing 2990 by 689, we get 4 with a remainder of 234.
The next digit of our result is 4. 
Result so far: 28664.6415094
The remainder is 234 after subtracting 2756 from 2990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Moving on to step 16:
If we divide 2340 by 689, we get 3 and a remainder of 273.
Write down 3 as next digit of the result. 
Result so far: 28664.64150943
The remainder is 273 after subtracting 2067 from 2340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

The final outcome is 28664.64150943, with a leftover of 2.73e-07.
