19730269 ÷ 688 
We want to figure out the number of times 19730269 can be divided by 688.

On to step 1:
688 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 688

Let's proceed to step 2:
When dividing 19 by 688, we get 0 with a remainder of 19.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 19 and we're left with 19.
Take the next digit (7) from the dividend and append it to 19, then repeat: 197 / 688

On to step 3:
If we divide 197 by 688, we get 0 and a remainder of 197.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 197, we end up with 197.
Grab the next digit (3) from the dividend, add it to 197, then carry on: 1973 / 688

Step 4:
1973 divided by 688 is 2 with a remainder of 597.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 1376 from 1973 and we're left with 597.
Grab the next digit (0) from the dividend, add it to 597, then carry on: 5970 / 688

Step 5:
688 goes into 5970 8 times with a remainder of 466.
The next digit of our result is 8. 
Result so far: 28.0
The remainder is 466 after subtracting 5504 from 5970.
Take the next digit (2) from the dividend and append it to 466, then repeat: 4662 / 688

On to step 6:
688 can be fit into 4662 6 times, resulting in a remainder of 534.
The next digit of our result is 6. 
Result so far: 286.0
If we subtract 4128 from 4662, we get 534.
Grab the next digit (6) from the dividend, add it to 534, then carry on: 5346 / 688

Let's proceed to step 7:
The number 688 fits into 5346 7 times, leaving a remainder of 530.
Use 7 as the next digit of our solution. 
Result so far: 2867.0
Deduct 4816 from 5346 and we're left with 530.
Include the next digit (9) from the dividend after 530, then repeat: 5309 / 688

Moving on to step 8:
688 can be fit into 5309 7 times, resulting in a remainder of 493.
Write down 7 as next digit of the result. 
Result so far: 28677.0
If we subtract 4816 from 5309, we get 493.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4930, and continue the process.

Step 9:
When dividing 4930 by 688, we get 7 with a remainder of 114.
Use 7 as the next digit of our solution. 
Result so far: 28677.7
The remainder is 114 after subtracting 4816 from 4930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Step 10:
When dividing 1140 by 688, we get 1 with a remainder of 452.
Put 1 as the next digit of the answer. 
Result so far: 28677.71
Subtract 688 from 1140 to get 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Going ahead to step 11:
688 can be fit into 4520 6 times, resulting in a remainder of 392.
Write down 6 as next digit of the result. 
Result so far: 28677.716
Subtract 4128 from 4520 to get 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Moving on to step 12:
The number 688 fits into 3920 5 times, leaving a remainder of 480.
The next digit of our result is 5. 
Result so far: 28677.7165
The remainder is 480 after subtracting 3440 from 3920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

On to step 13:
When dividing 4800 by 688, we get 6 with a remainder of 672.
Use 6 as the next digit of our solution. 
Result so far: 28677.71656
Subtract 4128 from 4800 to get 672.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

Going ahead to step 14:
When dividing 6720 by 688, we get 9 with a remainder of 528.
Put 9 as the next digit of the answer. 
Result so far: 28677.716569
Subtract 6192 from 6720 to get 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Moving on to step 15:
When dividing 5280 by 688, we get 7 with a remainder of 464.
Put 7 as the next digit of the answer. 
Result so far: 28677.7165697
If we subtract 4816 from 5280, we get 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Advancing to step 16:
The number 688 fits into 4640 6 times, leaving a remainder of 512.
The next digit of our result is 6. 
Result so far: 28677.71656976
Subtracting 4128 from 4640 leaves us with 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Our division results in 28677.71656976 with a remaining 5.12e-07.
