We're dividing 51230553 by 669 
We want to divide 51230553 by 669.

Moving on to step 1:
5 divided by 669 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 669

Going ahead to step 2:
If we divide 51 by 669, we get 0 and a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Append the next digit (2) from the dividend to 51 and continue with: 512 / 669

Step 3:
When dividing 512 by 669, we get 0 with a remainder of 512.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 512, we end up with 512.
Include the next digit (3) from the dividend after 512, then repeat: 5123 / 669

On to step 4:
669 can be fit into 5123 7 times, resulting in a remainder of 440.
Write down 7 as next digit of the result. 
Result so far: 7.0
Deduct 4683 from 5123 and we're left with 440.
Grab the next digit (0) from the dividend, add it to 440, then carry on: 4400 / 669

Step 5:
When dividing 4400 by 669, we get 6 with a remainder of 386.
Use 6 as the next digit of our solution. 
Result so far: 76.0
Subtract 4014 from 4400 to get 386.
Append the next digit (5) from the dividend to 386 and continue with: 3865 / 669

On to step 6:
If we divide 3865 by 669, we get 5 and a remainder of 520.
The next digit of our result is 5. 
Result so far: 765.0
Deduct 3345 from 3865 and we're left with 520.
Grab the next digit (5) from the dividend, add it to 520, then carry on: 5205 / 669

Moving on to step 7:
669 goes into 5205 7 times with a remainder of 522.
Write down 7 as next digit of the result. 
Result so far: 7657.0
Deduct 4683 from 5205 and we're left with 522.
Include the next digit (3) from the dividend after 522, then repeat: 5223 / 669

Step 8:
The number 669 fits into 5223 7 times, leaving a remainder of 540.
Use 7 as the next digit of our solution. 
Result so far: 76577.0
Subtract 4683 from 5223 to get 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Advancing to step 9:
The number 669 fits into 5400 8 times, leaving a remainder of 48.
Use 8 as the next digit of our solution. 
Result so far: 76577.8
Subtract 5352 from 5400 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 10:
669 can be fit into 480 0 times, resulting in a remainder of 480.
Write down 0 as next digit of the result. 
Result so far: 76577.8
Subtract 0 from 480 to get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Going ahead to step 11:
If we divide 4800 by 669, we get 7 and a remainder of 117.
Write down 7 as next digit of the result. 
Result so far: 76577.807
If we subtract 4683 from 4800, we get 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Going ahead to step 12:
669 goes into 1170 1 times with a remainder of 501.
Record the quotient 1 as the next digit in the result. 
Result so far: 76577.8071
If we subtract 669 from 1170, we get 501.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5010, and continue the process.

Step 13:
5010 divided by 669 is 7 with a remainder of 327.
Write down 7 as next digit of the result. 
Result so far: 76577.80717
The remainder is 327 after subtracting 4683 from 5010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

On to step 14:
The number 669 fits into 3270 4 times, leaving a remainder of 594.
The number 4 becomes the next digit in our result. 
Result so far: 76577.807174
If we take 2676 away from 3270, we end up with 594.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5940, and continue the process.

Moving on to step 15:
669 goes into 5940 8 times with a remainder of 588.
Put 8 as the next digit of the answer. 
Result so far: 76577.8071748
Subtracting 5352 from 5940 leaves us with 588.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5880, and continue the process.

Going ahead to step 16:
When dividing 5880 by 669, we get 8 with a remainder of 528.
Use 8 as the next digit of our solution. 
Result so far: 76577.80717488
If we take 5352 away from 5880, we end up with 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

The quotient of the division is 76577.80717488, and the remainder is 5.28e-07.
