51774918 ÷ 531 
We want to figure out the number of times 51774918 can be divided by 531.

Step 1:
When dividing 5 by 531, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 531

On to step 2:
531 goes into 51 0 times with a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Bring next digit (7) of the dividend behind the 51 and repeat the process: 517 / 531

Advancing to step 3:
517 divided by 531 is 0 with a remainder of 517.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 517 leaves us with 517.
Append the next digit (7) from the dividend to 517 and continue with: 5177 / 531

Moving on to step 4:
The number 531 fits into 5177 9 times, leaving a remainder of 398.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtract 4779 from 5177 to get 398.
Append the next digit (4) from the dividend to 398 and continue with: 3984 / 531

Going ahead to step 5:
531 can be fit into 3984 7 times, resulting in a remainder of 267.
Put 7 as the next digit of the answer. 
Result so far: 97.0
If we subtract 3717 from 3984, we get 267.
Append the next digit (9) from the dividend to 267 and continue with: 2679 / 531

Moving on to step 6:
531 can be fit into 2679 5 times, resulting in a remainder of 24.
The next digit of our result is 5. 
Result so far: 975.0
If we subtract 2655 from 2679, we get 24.
Take the next digit (1) from the dividend and append it to 24, then repeat: 241 / 531

Step 7:
531 goes into 241 0 times with a remainder of 241.
The number 0 becomes the next digit in our result. 
Result so far: 9750.0
If we take 0 away from 241, we end up with 241.
Take the next digit (8) from the dividend and append it to 241, then repeat: 2418 / 531

On to step 8:
2418 divided by 531 is 4 with a remainder of 294.
Put 4 as the next digit of the answer. 
Result so far: 97504.0
Subtracting 2124 from 2418 leaves us with 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Advancing to step 9:
2940 divided by 531 is 5 with a remainder of 285.
Put 5 as the next digit of the answer. 
Result so far: 97504.5
Deduct 2655 from 2940 and we're left 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 10:
531 goes into 2850 5 times with a remainder of 195.
The next digit of our result is 5. 
Result so far: 97504.55
If we subtract 2655 from 2850, we get 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

The final outcome is 97504.55, with a leftover of 0.195.
