51670133 ÷ 664 
We want to figure out the number of times 51670133 can be divided by 664.

Advancing to step 1:
If we divide 5 by 664, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 664

Let's proceed to step 2:
When dividing 51 by 664, we get 0 with a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Fetch the next digit (6) from the dividend, attach it to 51 and continue: 516 / 664

On to step 3:
When dividing 516 by 664, we get 0 with a remainder of 516.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 516, we get 516.
Append the next digit (7) from the dividend to 516 and continue with: 5167 / 664

Going ahead to step 4:
5167 divided by 664 is 7 with a remainder of 519.
The next digit of our result is 7. 
Result so far: 7.0
The remainder is 519 after subtracting 4648 from 5167.
Fetch the next digit (0) from the dividend, attach it to 519 and continue: 5190 / 664

Step 5:
5190 divided by 664 is 7 with a remainder of 542.
Write down 7 as next digit of the result. 
Result so far: 77.0
Subtract 4648 from 5190 to get 542.
Bring next digit (1) of the dividend behind the 542 and repeat the process: 5421 / 664

Advancing to step 6:
When dividing 5421 by 664, we get 8 with a remainder of 109.
The number 8 becomes the next digit in our result. 
Result so far: 778.0
If we take 5312 away from 5421, we end up with 109.
Fetch the next digit (3) from the dividend, attach it to 109 and continue: 1093 / 664

On to step 7:
664 goes into 1093 1 times with a remainder of 429.
Write down 1 as next digit of the result. 
Result so far: 7781.0
If we subtract 664 from 1093, we get 429.
Fetch the next digit (3) from the dividend, attach it to 429 and continue: 4293 / 664

On to step 8:
The number 664 fits into 4293 6 times, leaving a remainder of 309.
The number 6 becomes the next digit in our result. 
Result so far: 77816.0
Subtract 3984 from 4293 to get 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

On to step 9:
When dividing 3090 by 664, we get 4 with a remainder of 434.
Put 4 as the next digit of the answer. 
Result so far: 77816.4
Deduct 2656 from 3090 and we're left with 434.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

Advancing to step 10:
664 can be fit into 4340 6 times, resulting in a remainder of 356.
Put 6 as the next digit of the answer. 
Result so far: 77816.46
Deduct 3984 from 4340 and we're left with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Step 11:
3560 divided by 664 is 5 with a remainder of 240.
Put 5 as the next digit of the answer. 
Result so far: 77816.465
Deduct 3320 from 3560 and we're left with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 12:
When dividing 2400 by 664, we get 3 with a remainder of 408.
Record the quotient 3 as the next digit in the result. 
Result so far: 77816.4653
Deduct 1992 from 2400 and we're left with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Let's proceed to step 13:
4080 divided by 664 is 6 with a remainder of 96.
Record the quotient 6 as the next digit in the result. 
Result so far: 77816.46536
If we take 3984 away from 4080, we end up with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

On to step 14:
664 goes into 960 1 times with a remainder of 296.
The next digit of our result is 1. 
Result so far: 77816.465361
The remainder is 296 after subtracting 664 from 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Step 15:
The number 664 fits into 2960 4 times, leaving a remainder of 304.
Record the quotient 4 as the next digit in the result. 
Result so far: 77816.4653614
Deduct 2656 from 2960 and we're left with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

On to step 16:
The number 664 fits into 3040 4 times, leaving a remainder of 384.
The next digit of our result is 4. 
Result so far: 77816.46536144
If we take 2656 away from 3040, we end up with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

The final result is 77816.46536144 with a remainder of 3.84e-07.
