51985101 ÷ 566 
Let's see how many times 566 fits into 51985101.

Moving on to step 1:
The number 566 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 566

Let's proceed to step 2:
The number 566 fits into 51 0 times, leaving a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Fetch the next digit (9) from the dividend, attach it to 51 and continue: 519 / 566

Step 3:
566 can be fit into 519 0 times, resulting in a remainder of 519.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 519, we get 519.
Bring next digit (8) of the dividend behind the 519 and repeat the process: 5198 / 566

Moving on to step 4:
When dividing 5198 by 566, we get 9 with a remainder of 104.
The next digit of our result is 9. 
Result so far: 9.0
Deduct 5094 from 5198 and we're left with 104.
Grab the next digit (5) from the dividend, add it to 104, then carry on: 1045 / 566

On to step 5:
If we divide 1045 by 566, we get 1 and a remainder of 479.
The next digit of our result is 1. 
Result so far: 91.0
Deduct 566 from 1045 and we're left with 479.
Grab the next digit (1) from the dividend, add it to 479, then carry on: 4791 / 566

Step 6:
566 goes into 4791 8 times with a remainder of 263.
Use 8 as the next digit of our solution. 
Result so far: 918.0
The remainder is 263 after subtracting 4528 from 4791.
Take the next digit (0) from the dividend and append it to 263, then repeat: 2630 / 566

Moving on to step 7:
566 goes into 2630 4 times with a remainder of 366.
Write down 4 as next digit of the result. 
Result so far: 9184.0
If we subtract 2264 from 2630, we get 366.
Include the next digit (1) from the dividend after 366, then repeat: 3661 / 566

Going ahead to step 8:
566 can be fit into 3661 6 times, resulting in a remainder of 265.
The number 6 becomes the next digit in our result. 
Result so far: 91846.0
Subtracting 3396 from 3661 leaves us with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Moving on to step 9:
566 goes into 2650 4 times with a remainder of 386.
The number 4 becomes the next digit in our result. 
Result so far: 91846.4
Subtract 2264 from 2650 to get 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

On to step 10:
3860 divided by 566 is 6 with a remainder of 464.
Use 6 as the next digit of our solution. 
Result so far: 91846.46
If we take 3396 away from 3860, we end up with 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Moving on to step 11:
When dividing 4640 by 566, we get 8 with a remainder of 112.
The next digit of our result is 8. 
Result so far: 91846.468
Subtract 4528 from 4640 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Moving on to step 12:
566 can be fit into 1120 1 times, resulting in a remainder of 554.
The next digit of our result is 1. 
Result so far: 91846.4681
Deduct 566 from 1120 and we're left with 554.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5540, and continue the process.

On to step 13:
5540 divided by 566 is 9 with a remainder of 446.
The number 9 becomes the next digit in our result. 
Result so far: 91846.46819
Subtract 5094 from 5540 to get 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

Advancing to step 14:
When dividing 4460 by 566, we get 7 with a remainder of 498.
Write down 7 as next digit of the result. 
Result so far: 91846.468197
Subtracting 3962 from 4460 leaves us with 498.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4980, and continue the process.

Let's proceed to step 15:
The number 566 fits into 4980 8 times, leaving a remainder of 452.
The number 8 becomes the next digit in our result. 
Result so far: 91846.4681978
If we take 4528 away from 4980, we end up with 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

On to step 16:
566 goes into 4520 7 times with a remainder of 558.
Put 7 as the next digit of the answer. 
Result so far: 91846.46819787
If we subtract 3962 from 4520, we get 558.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5580, and continue the process.

The final outcome is 91846.46819787, with a leftover of 5.58e-07.
