51666314 divided by 747 
We want to figure out the number of times 51666314 can be divided by 747.

Moving on to step 1:
5 divided by 747 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 747

Going ahead to step 2:
The number 747 fits into 51 0 times, leaving a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Include the next digit (6) from the dividend after 51, then repeat: 516 / 747

Step 3:
747 goes into 516 0 times with a remainder of 516.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 516 to get 516.
Append the next digit (6) from the dividend to 516 and continue with: 5166 / 747

Step 4:
5166 divided by 747 is 6 with a remainder of 684.
The next digit of our result is 6. 
Result so far: 6.0
Deduct 4482 from 5166 and we're left with 684.
Bring next digit (6) of the dividend behind the 684 and repeat the process: 6846 / 747

Moving on to step 5:
When dividing 6846 by 747, we get 9 with a remainder of 123.
Put 9 as the next digit of the answer. 
Result so far: 69.0
Subtract 6723 from 6846 to get 123.
Take the next digit (3) from the dividend and append it to 123, then repeat: 1233 / 747

Advancing to step 6:
1233 divided by 747 is 1 with a remainder of 486.
Put 1 as the next digit of the answer. 
Result so far: 691.0
Deduct 747 from 1233 and we're left with 486.
Fetch the next digit (1) from the dividend, attach it to 486 and continue: 4861 / 747

Going ahead to step 7:
747 can be fit into 4861 6 times, resulting in a remainder of 379.
Record the quotient 6 as the next digit in the result. 
Result so far: 6916.0
The remainder is 379 after subtracting 4482 from 4861.
Take the next digit (4) from the dividend and append it to 379, then repeat: 3794 / 747

On to step 8:
The number 747 fits into 3794 5 times, leaving a remainder of 59.
Use 5 as the next digit of our solution. 
Result so far: 69165.0
If we take 3735 away from 3794, we end up with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Step 9:
When dividing 590 by 747, we get 0 with a remainder of 590.
Put 0 as the next digit of the answer. 
Result so far: 69165.0
If we take 0 away from 590, we end up with 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Let's proceed to step 10:
747 goes into 5900 7 times with a remainder of 671.
The number 7 becomes the next digit in our result. 
Result so far: 69165.07
Subtracting 5229 from 5900 leaves us with 671.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6710, and continue the process.

Moving on to step 11:
747 can be fit into 6710 8 times, resulting in a remainder of 734.
Write down 8 as next digit of the result. 
Result so far: 69165.078
Deduct 5976 from 6710 and we're left with 734.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7340, and continue the process.

On to step 12:
747 goes into 7340 9 times with a remainder of 617.
Record the quotient 9 as the next digit in the result. 
Result so far: 69165.0789
The remainder is 617 after subtracting 6723 from 7340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6170, and continue the process.

Going ahead to step 13:
6170 divided by 747 is 8 with a remainder of 194.
Record the quotient 8 as the next digit in the result. 
Result so far: 69165.07898
If we subtract 5976 from 6170, we get 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

On to step 14:
747 goes into 1940 2 times with a remainder of 446.
Use 2 as the next digit of our solution. 
Result so far: 69165.078982
Subtracting 1494 from 1940 leaves us with 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

On to step 15:
747 can be fit into 4460 5 times, resulting in a remainder of 725.
Record the quotient 5 as the next digit in the result. 
Result so far: 69165.0789825
Subtract 3735 from 4460 to get 725.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7250, and continue the process.

Step 16:
747 goes into 7250 9 times with a remainder of 527.
Record the quotient 9 as the next digit in the result. 
Result so far: 69165.07898259
Subtracting 6723 from 7250 leaves us with 527.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5270, and continue the process.

After the division, we end up with 69165.07898259 and a remainder of 5.27e-07.
