51456963 divided by 875 
We want to figure out the number of times 51456963 can be divided by 875.

Step 1:
875 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 875

Step 2:
The number 875 fits into 51 0 times, leaving a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Include the next digit (4) from the dividend after 51, then repeat: 514 / 875

Advancing to step 3:
The number 875 fits into 514 0 times, leaving a remainder of 514.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 514 after subtracting 0 from 514.
Take the next digit (5) from the dividend and append it to 514, then repeat: 5145 / 875

On to step 4:
If we divide 5145 by 875, we get 5 and a remainder of 770.
The next digit of our result is 5. 
Result so far: 5.0
Deduct 4375 from 5145 and we're left with 770.
Append the next digit (6) from the dividend to 770 and continue with: 7706 / 875

Advancing to step 5:
875 can be fit into 7706 8 times, resulting in a remainder of 706.
The next digit of our result is 8. 
Result so far: 58.0
Deduct 7000 from 7706 and we're left with 706.
Fetch the next digit (9) from the dividend, attach it to 706 and continue: 7069 / 875

Advancing to step 6:
The number 875 fits into 7069 8 times, leaving a remainder of 69.
The number 8 becomes the next digit in our result. 
Result so far: 588.0
The remainder is 69 after subtracting 7000 from 7069.
Take the next digit (6) from the dividend and append it to 69, then repeat: 696 / 875

Let's proceed to step 7:
When dividing 696 by 875, we get 0 with a remainder of 696.
Write down 0 as next digit of the result. 
Result so far: 5880.0
If we take 0 away from 696, we end up with 696.
Bring next digit (3) of the dividend behind the 696 and repeat the process: 6963 / 875

Step 8:
875 goes into 6963 7 times with a remainder of 838.
Use 7 as the next digit of our solution. 
Result so far: 58807.0
Deduct 6125 from 6963 and we're left with 838.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8380, and continue the process.

Moving on to step 9:
8380 divided by 875 is 9 with a remainder of 505.
The number 9 becomes the next digit in our result. 
Result so far: 58807.9
Deduct 7875 from 8380 and we're left with 505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

Let's proceed to step 10:
875 can be fit into 5050 5 times, resulting in a remainder of 675.
Record the quotient 5 as the next digit in the result. 
Result so far: 58807.95
The remainder is 675 after subtracting 4375 from 5050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6750, and continue the process.

On to step 11:
When dividing 6750 by 875, we get 7 with a remainder of 625.
Record the quotient 7 as the next digit in the result. 
Result so far: 58807.957
If we subtract 6125 from 6750, we get 625.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6250, and continue the process.

Moving on to step 12:
6250 divided by 875 is 7 with a remainder of 125.
The next digit of our result is 7. 
Result so far: 58807.9577
The remainder is 125 after subtracting 6125 from 6250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

The final outcome is 58807.9577, with a leftover of 0.00125.
