55899973 ÷ 716 
Our goal is to divide 55899973 by 716.

Let's proceed to step 1:
The number 716 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 716

Let's proceed to step 2:
When dividing 55 by 716, we get 0 with a remainder of 55.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 55, we end up with 55.
Take the next digit (8) from the dividend and append it to 55, then repeat: 558 / 716

Going ahead to step 3:
The number 716 fits into 558 0 times, leaving a remainder of 558.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 558 after subtracting 0 from 558.
Take the next digit (9) from the dividend and append it to 558, then repeat: 5589 / 716

Let's proceed to step 4:
716 goes into 5589 7 times with a remainder of 577.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Deduct 5012 from 5589 and we're left with 577.
Bring next digit (9) of the dividend behind the 577 and repeat the process: 5779 / 716

Step 5:
5779 divided by 716 is 8 with a remainder of 51.
The number 8 becomes the next digit in our result. 
Result so far: 78.0
If we take 5728 away from 5779, we end up with 51.
Append the next digit (9) from the dividend to 51 and continue with: 519 / 716

Advancing to step 6:
716 can be fit into 519 0 times, resulting in a remainder of 519.
Record the quotient 0 as the next digit in the result. 
Result so far: 780.0
Subtracting 0 from 519 leaves us with 519.
Include the next digit (7) from the dividend after 519, then repeat: 5197 / 716

Step 7:
If we divide 5197 by 716, we get 7 and a remainder of 185.
Use 7 as the next digit of our solution. 
Result so far: 7807.0
Subtracting 5012 from 5197 leaves us with 185.
Fetch the next digit (3) from the dividend, attach it to 185 and continue: 1853 / 716

On to step 8:
If we divide 1853 by 716, we get 2 and a remainder of 421.
The next digit of our result is 2. 
Result so far: 78072.0
Subtract 1432 from 1853 to get 421.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4210, and continue the process.

Going ahead to step 9:
The number 716 fits into 4210 5 times, leaving a remainder of 630.
Put 5 as the next digit of the answer. 
Result so far: 78072.5
If we take 3580 away from 4210, we end up with 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Going ahead to step 10:
716 can be fit into 6300 8 times, resulting in a remainder of 572.
The next digit of our result is 8. 
Result so far: 78072.58
The remainder is 572 after subtracting 5728 from 6300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5720, and continue the process.

Step 11:
716 goes into 5720 7 times with a remainder of 708.
The next digit of our result is 7. 
Result so far: 78072.587
Deduct 5012 from 5720 and we're left with 708.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7080, and continue the process.

Advancing to step 12:
716 can be fit into 7080 9 times, resulting in a remainder of 636.
Record the quotient 9 as the next digit in the result. 
Result so far: 78072.5879
The remainder is 636 after subtracting 6444 from 7080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

Let's proceed to step 13:
716 can be fit into 6360 8 times, resulting in a remainder of 632.
The next digit of our result is 8. 
Result so far: 78072.58798
If we take 5728 away from 6360, we end up with 632.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

On to step 14:
The number 716 fits into 6320 8 times, leaving a remainder of 592.
The number 8 becomes the next digit in our result. 
Result so far: 78072.587988
If we subtract 5728 from 6320, we get 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

The final outcome is 78072.587988, with a leftover of 5.92e-05.
