We're dividing 51565921 by 706 
We want to figure out the number of times 51565921 can be divided by 706.

Going ahead to step 1:
The number 706 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 706

On to step 2:
The number 706 fits into 51 0 times, leaving a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Take the next digit (5) from the dividend and append it to 51, then repeat: 515 / 706

Advancing to step 3:
706 goes into 515 0 times with a remainder of 515.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 515 after subtracting 0 from 515.
Take the next digit (6) from the dividend and append it to 515, then repeat: 5156 / 706

Going ahead to step 4:
5156 divided by 706 is 7 with a remainder of 214.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we subtract 4942 from 5156, we get 214.
Include the next digit (5) from the dividend after 214, then repeat: 2145 / 706

Going ahead to step 5:
The number 706 fits into 2145 3 times, leaving a remainder of 27.
The number 3 becomes the next digit in our result. 
Result so far: 73.0
The remainder is 27 after subtracting 2118 from 2145.
Bring next digit (9) of the dividend behind the 27 and repeat the process: 279 / 706

Moving on to step 6:
The number 706 fits into 279 0 times, leaving a remainder of 279.
The next digit of our result is 0. 
Result so far: 730.0
Deduct 0 from 279 and we're left with 279.
Take the next digit (2) from the dividend and append it to 279, then repeat: 2792 / 706

Moving on to step 7:
When dividing 2792 by 706, we get 3 with a remainder of 674.
Put 3 as the next digit of the answer. 
Result so far: 7303.0
If we subtract 2118 from 2792, we get 674.
Take the next digit (1) from the dividend and append it to 674, then repeat: 6741 / 706

On to step 8:
The number 706 fits into 6741 9 times, leaving a remainder of 387.
The next digit of our result is 9. 
Result so far: 73039.0
Subtract 6354 from 6741 to get 387.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3870, and continue the process.

Moving on to step 9:
When dividing 3870 by 706, we get 5 with a remainder of 340.
The number 5 becomes the next digit in our result. 
Result so far: 73039.5
If we subtract 3530 from 3870, we get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Step 10:
When dividing 3400 by 706, we get 4 with a remainder of 576.
The next digit of our result is 4. 
Result so far: 73039.54
Subtracting 2824 from 3400 leaves us with 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Step 11:
When dividing 5760 by 706, we get 8 with a remainder of 112.
Put 8 as the next digit of the answer. 
Result so far: 73039.548
The remainder is 112 after subtracting 5648 from 5760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Step 12:
1120 divided by 706 is 1 with a remainder of 414.
Use 1 as the next digit of our solution. 
Result so far: 73039.5481
The remainder is 414 after subtracting 706 from 1120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

Step 13:
The number 706 fits into 4140 5 times, leaving a remainder of 610.
The next digit of our result is 5. 
Result so far: 73039.54815
Subtracting 3530 from 4140 leaves us with 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Moving on to step 14:
When dividing 6100 by 706, we get 8 with a remainder of 452.
Use 8 as the next digit of our solution. 
Result so far: 73039.548158
Subtract 5648 from 6100 to get 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Advancing to step 15:
4520 divided by 706 is 6 with a remainder of 284.
Use 6 as the next digit of our solution. 
Result so far: 73039.5481586
If we take 4236 away from 4520, we end up with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Step 16:
If we divide 2840 by 706, we get 4 and a remainder of 16.
The next digit of our result is 4. 
Result so far: 73039.54815864
Deduct 2824 from 2840 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 73039.54815864, with a leftover of 1.6e-08.
