We divide 51142569 by 859
We want to divide 51142569 by 859.

Going ahead to step 1:
5 divided by 859 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
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 / 859

Moving on to step 2:
51 divided by 859 is 0 with a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Fetch the next digit (1) from the dividend, attach it to 51 and continue: 511 / 859

Let's proceed to step 3:
859 goes into 511 0 times with a remainder of 511.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 511, we get 511.
Include the next digit (4) from the dividend after 511, then repeat: 5114 / 859

Going ahead to step 4:
859 goes into 5114 5 times with a remainder of 819.
Write down 5 as next digit of the result. 
Result so far: 5.0
Deduct 4295 from 5114 and we're left with 819.
Bring next digit (2) of the dividend behind the 819 and repeat the process: 8192 / 859

Going ahead to step 5:
The number 859 fits into 8192 9 times, leaving a remainder of 461.
Write down 9 as next digit of the result. 
Result so far: 59.0
Subtracting 7731 from 8192 leaves us with 461.
Take the next digit (5) from the dividend and append it to 461, then repeat: 4615 / 859

Going ahead to step 6:
The number 859 fits into 4615 5 times, leaving a remainder of 320.
Put 5 as the next digit of the answer. 
Result so far: 595.0
Deduct 4295 from 4615 and we're left with 320.
Take the next digit (6) from the dividend and append it to 320, then repeat: 3206 / 859

Let's proceed to step 7:
859 goes into 3206 3 times with a remainder of 629.
The next digit of our result is 3. 
Result so far: 5953.0
If we take 2577 away from 3206, we end up with 629.
Take the next digit (9) from the dividend and append it to 629, then repeat: 6299 / 859

Advancing to step 8:
The number 859 fits into 6299 7 times, leaving a remainder of 286.
The next digit of our result is 7. 
Result so far: 59537.0
The remainder is 286 after subtracting 6013 from 6299.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Step 9:
The number 859 fits into 2860 3 times, leaving a remainder of 283.
Write down 3 as next digit of the result. 
Result so far: 59537.3
Subtracting 2577 from 2860 leaves us with 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

On to step 10:
If we divide 2830 by 859, we get 3 and a remainder of 253.
The number 3 becomes the next digit in our result. 
Result so far: 59537.33
If we take 2577 away from 2830, we end up with 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

In conclusion, the division gives 59537.33 with a balance of 0.253.
