We look at the division of 50313566 by 689 
We want to figure out the number of times 50313566 can be divided by 689.

On to step 1:
689 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 689

Moving on to step 2:
689 can be fit into 50 0 times, resulting in a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 50, we get 50.
Take the next digit (3) from the dividend and append it to 50, then repeat: 503 / 689

Moving on to step 3:
If we divide 503 by 689, we get 0 and a remainder of 503.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 503 to get 503.
Fetch the next digit (1) from the dividend, attach it to 503 and continue: 5031 / 689

Moving on to step 4:
5031 divided by 689 is 7 with a remainder of 208.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 4823 from 5031, we get 208.
Fetch the next digit (3) from the dividend, attach it to 208 and continue: 2083 / 689

On to step 5:
When dividing 2083 by 689, we get 3 with a remainder of 16.
Record the quotient 3 as the next digit in the result. 
Result so far: 73.0
Deduct 2067 from 2083 and we're left with 16.
Append the next digit (5) from the dividend to 16 and continue with: 165 / 689

Step 6:
689 goes into 165 0 times with a remainder of 165.
Use 0 as the next digit of our solution. 
Result so far: 730.0
Subtracting 0 from 165 leaves us with 165.
Take the next digit (6) from the dividend and append it to 165, then repeat: 1656 / 689

Moving on to step 7:
The number 689 fits into 1656 2 times, leaving a remainder of 278.
Record the quotient 2 as the next digit in the result. 
Result so far: 7302.0
Subtracting 1378 from 1656 leaves us with 278.
Grab the next digit (6) from the dividend, add it to 278, then carry on: 2786 / 689

Going ahead to step 8:
When dividing 2786 by 689, we get 4 with a remainder of 30.
Record the quotient 4 as the next digit in the result. 
Result so far: 73024.0
If we subtract 2756 from 2786, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 9:
689 can be fit into 300 0 times, resulting in a remainder of 300.
The number 0 becomes the next digit in our result. 
Result so far: 73024.0
The remainder is 300 after subtracting 0 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Going ahead to step 10:
The number 689 fits into 3000 4 times, leaving a remainder of 244.
Write down 4 as next digit of the result. 
Result so far: 73024.04
The remainder is 244 after subtracting 2756 from 3000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

On to step 11:
When dividing 2440 by 689, we get 3 with a remainder of 373.
The number 3 becomes the next digit in our result. 
Result so far: 73024.043
If we take 2067 away from 2440, we end up with 373.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3730, and continue the process.

Advancing to step 12:
689 goes into 3730 5 times with a remainder of 285.
The next digit of our result is 5. 
Result so far: 73024.0435
Subtracting 3445 from 3730 leaves us with 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

On to step 13:
689 goes into 2850 4 times with a remainder of 94.
The next digit of our result is 4. 
Result so far: 73024.04354
If we subtract 2756 from 2850, we get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Advancing to step 14:
940 divided by 689 is 1 with a remainder of 251.
Use 1 as the next digit of our solution. 
Result so far: 73024.043541
If we take 689 away from 940, we end up with 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

Advancing to step 15:
When dividing 2510 by 689, we get 3 with a remainder of 443.
Use 3 as the next digit of our solution. 
Result so far: 73024.0435413
The remainder is 443 after subtracting 2067 from 2510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4430, and continue the process.

On to step 16:
689 can be fit into 4430 6 times, resulting in a remainder of 296.
The next digit of our result is 6. 
Result so far: 73024.04354136
Subtract 4134 from 4430 to get 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

The quotient of the division is 73024.04354136, and the remainder is 2.96e-07.
