51092511 ÷ 560 
We want to figure out the number of times 51092511 can be divided by 560.

Going ahead to step 1:
560 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
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 / 560

Going ahead to step 2:
51 divided by 560 is 0 with a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Fetch the next digit (0) from the dividend, attach it to 51 and continue: 510 / 560

Moving on to step 3:
560 goes into 510 0 times with a remainder of 510.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 510 to get 510.
Take the next digit (9) from the dividend and append it to 510, then repeat: 5109 / 560

Moving on to step 4:
When dividing 5109 by 560, we get 9 with a remainder of 69.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we subtract 5040 from 5109, we get 69.
Bring next digit (2) of the dividend behind the 69 and repeat the process: 692 / 560

Advancing to step 5:
The number 560 fits into 692 1 times, leaving a remainder of 132.
Record the quotient 1 as the next digit in the result. 
Result so far: 91.0
Subtract 560 from 692 to get 132.
Grab the next digit (5) from the dividend, add it to 132, then carry on: 1325 / 560

Advancing to step 6:
560 goes into 1325 2 times with a remainder of 205.
Use 2 as the next digit of our solution. 
Result so far: 912.0
Subtracting 1120 from 1325 leaves us with 205.
Append the next digit (1) from the dividend to 205 and continue with: 2051 / 560

On to step 7:
560 goes into 2051 3 times with a remainder of 371.
Use 3 as the next digit of our solution. 
Result so far: 9123.0
Deduct 1680 from 2051 and we're left with 371.
Take the next digit (1) from the dividend and append it to 371, then repeat: 3711 / 560

Moving on to step 8:
If we divide 3711 by 560, we get 6 and a remainder of 351.
The number 6 becomes the next digit in our result. 
Result so far: 91236.0
If we subtract 3360 from 3711, we get 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

On to step 9:
The number 560 fits into 3510 6 times, leaving a remainder of 150.
The number 6 becomes the next digit in our result. 
Result so far: 91236.6
Deduct 3360 from 3510 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Let's proceed to step 10:
When dividing 1500 by 560, we get 2 with a remainder of 380.
The next digit of our result is 2. 
Result so far: 91236.62
The remainder is 380 after subtracting 1120 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

On to step 11:
3800 divided by 560 is 6 with a remainder of 440.
The next digit of our result is 6. 
Result so far: 91236.626
The remainder is 440 after subtracting 3360 from 3800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

On to step 12:
If we divide 4400 by 560, we get 7 and a remainder of 480.
Use 7 as the next digit of our solution. 
Result so far: 91236.6267
Subtracting 3920 from 4400 leaves us with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Let's proceed to step 13:
560 can be fit into 4800 8 times, resulting in a remainder of 320.
Put 8 as the next digit of the answer. 
Result so far: 91236.62678
If we subtract 4480 from 4800, we get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

On to step 14:
When dividing 3200 by 560, we get 5 with a remainder of 400.
Use 5 as the next digit of our solution. 
Result so far: 91236.626785
If we subtract 2800 from 3200, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Going ahead to step 15:
When dividing 4000 by 560, we get 7 with a remainder of 80.
The next digit of our result is 7. 
Result so far: 91236.6267857
Deduct 3920 from 4000 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 16:
800 divided by 560 is 1 with a remainder of 240.
The number 1 becomes the next digit in our result. 
Result so far: 91236.62678571
Subtract 560 from 800 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

In conclusion, the division gives 91236.62678571 with a balance of 2.4e-07.
