We look at the division of 50510564 by 669 
We want to divide 50510564 by 669.

Advancing to step 1:
If we divide 5 by 669, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 669

Moving on to step 2:
669 can be fit into 50 0 times, resulting in a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 50 after subtracting 0 from 50.
Append the next digit (5) from the dividend to 50 and continue with: 505 / 669

Step 3:
When dividing 505 by 669, we get 0 with a remainder of 505.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 505 leaves us with 505.
Append the next digit (1) from the dividend to 505 and continue with: 5051 / 669

Advancing to step 4:
The number 669 fits into 5051 7 times, leaving a remainder of 368.
The next digit of our result is 7. 
Result so far: 7.0
The remainder is 368 after subtracting 4683 from 5051.
Append the next digit (0) from the dividend to 368 and continue with: 3680 / 669

On to step 5:
The number 669 fits into 3680 5 times, leaving a remainder of 335.
Write down 5 as next digit of the result. 
Result so far: 75.0
Subtract 3345 from 3680 to get 335.
Take the next digit (5) from the dividend and append it to 335, then repeat: 3355 / 669

Going ahead to step 6:
3355 divided by 669 is 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 755.0
Deduct 3345 from 3355 and we're left with 10.
Fetch the next digit (6) from the dividend, attach it to 10 and continue: 106 / 669

Step 7:
106 divided by 669 is 0 with a remainder of 106.
Write down 0 as next digit of the result. 
Result so far: 7550.0
Deduct 0 from 106 and we're left with 106.
Append the next digit (4) from the dividend to 106 and continue with: 1064 / 669

Moving on to step 8:
669 goes into 1064 1 times with a remainder of 395.
Write down 1 as next digit of the result. 
Result so far: 75501.0
If we subtract 669 from 1064, we get 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

Going ahead to step 9:
When dividing 3950 by 669, we get 5 with a remainder of 605.
Put 5 as the next digit of the answer. 
Result so far: 75501.5
Subtract 3345 from 3950 to get 605.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6050, and continue the process.

Going ahead to step 10:
When dividing 6050 by 669, we get 9 with a remainder of 29.
Use 9 as the next digit of our solution. 
Result so far: 75501.59
If we take 6021 away from 6050, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 11:
669 goes into 290 0 times with a remainder of 290.
The next digit of our result is 0. 
Result so far: 75501.59
The remainder is 290 after subtracting 0 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Advancing to step 12:
669 can be fit into 2900 4 times, resulting in a remainder of 224.
Record the quotient 4 as the next digit in the result. 
Result so far: 75501.5904
Subtracting 2676 from 2900 leaves us with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Going ahead to step 13:
When dividing 2240 by 669, we get 3 with a remainder of 233.
Put 3 as the next digit of the answer. 
Result so far: 75501.59043
If we take 2007 away from 2240, we end up with 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

Moving on to step 14:
The number 669 fits into 2330 3 times, leaving a remainder of 323.
Record the quotient 3 as the next digit in the result. 
Result so far: 75501.590433
If we subtract 2007 from 2330, we get 323.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3230, and continue the process.

The final result is 75501.590433 with a remainder of 3.23e-05.
