51593351 ÷ 911 
We want to figure out the number of times 51593351 can be divided by 911.

Moving on to step 1:
The number 911 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 911

Moving on to step 2:
911 goes into 51 0 times with a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Bring next digit (5) of the dividend behind the 51 and repeat the process: 515 / 911

Step 3:
The number 911 fits into 515 0 times, leaving a remainder of 515.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 515 and we're left with 515.
Take the next digit (9) from the dividend and append it to 515, then repeat: 5159 / 911

Step 4:
5159 divided by 911 is 5 with a remainder of 604.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we subtract 4555 from 5159, we get 604.
Fetch the next digit (3) from the dividend, attach it to 604 and continue: 6043 / 911

Moving on to step 5:
When dividing 6043 by 911, we get 6 with a remainder of 577.
Put 6 as the next digit of the answer. 
Result so far: 56.0
The remainder is 577 after subtracting 5466 from 6043.
Grab the next digit (3) from the dividend, add it to 577, then carry on: 5773 / 911

Going ahead to step 6:
The number 911 fits into 5773 6 times, leaving a remainder of 307.
The number 6 becomes the next digit in our result. 
Result so far: 566.0
Deduct 5466 from 5773 and we're left with 307.
Fetch the next digit (5) from the dividend, attach it to 307 and continue: 3075 / 911

On to step 7:
When dividing 3075 by 911, we get 3 with a remainder of 342.
The number 3 becomes the next digit in our result. 
Result so far: 5663.0
The remainder is 342 after subtracting 2733 from 3075.
Take the next digit (1) from the dividend and append it to 342, then repeat: 3421 / 911

Going ahead to step 8:
911 goes into 3421 3 times with a remainder of 688.
Put 3 as the next digit of the answer. 
Result so far: 56633.0
Subtract 2733 from 3421 to get 688.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6880, and continue the process.

Advancing to step 9:
If we divide 6880 by 911, we get 7 and a remainder of 503.
The number 7 becomes the next digit in our result. 
Result so far: 56633.7
Subtracting 6377 from 6880 leaves us with 503.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5030, and continue the process.

On to step 10:
When dividing 5030 by 911, we get 5 with a remainder of 475.
Write down 5 as next digit of the result. 
Result so far: 56633.75
Deduct 4555 from 5030 and we're left with 475.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

Moving on to step 11:
911 can be fit into 4750 5 times, resulting in a remainder of 195.
The next digit of our result is 5. 
Result so far: 56633.755
If we subtract 4555 from 4750, 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 quotient of the division is 56633.755, and the remainder is 0.0195.
