We're dividing 54240851 by 859 
We want to figure out the number of times 54240851 can be divided by 859.

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.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 859

Step 2:
When dividing 54 by 859, we get 0 with a remainder of 54.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 54, we get 54.
Append the next digit (2) from the dividend to 54 and continue with: 542 / 859

Going ahead to step 3:
859 goes into 542 0 times with a remainder of 542.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 542 leaves us with 542.
Bring next digit (4) of the dividend behind the 542 and repeat the process: 5424 / 859

On to step 4:
The number 859 fits into 5424 6 times, leaving a remainder of 270.
Write down 6 as next digit of the result. 
Result so far: 6.0
The remainder is 270 after subtracting 5154 from 5424.
Bring next digit (0) of the dividend behind the 270 and repeat the process: 2700 / 859

Step 5:
If we divide 2700 by 859, we get 3 and a remainder of 123.
The next digit of our result is 3. 
Result so far: 63.0
Deduct 2577 from 2700 and we're left with 123.
Grab the next digit (8) from the dividend, add it to 123, then carry on: 1238 / 859

Let's proceed to step 6:
The number 859 fits into 1238 1 times, leaving a remainder of 379.
Record the quotient 1 as the next digit in the result. 
Result so far: 631.0
Deduct 859 from 1238 and we're left with 379.
Grab the next digit (5) from the dividend, add it to 379, then carry on: 3795 / 859

On to step 7:
If we divide 3795 by 859, we get 4 and a remainder of 359.
Record the quotient 4 as the next digit in the result. 
Result so far: 6314.0
Subtracting 3436 from 3795 leaves us with 359.
Include the next digit (1) from the dividend after 359, then repeat: 3591 / 859

Step 8:
If we divide 3591 by 859, we get 4 and a remainder of 155.
The number 4 becomes the next digit in our result. 
Result so far: 63144.0
The remainder is 155 after subtracting 3436 from 3591.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Step 9:
The number 859 fits into 1550 1 times, leaving a remainder of 691.
Put 1 as the next digit of the answer. 
Result so far: 63144.1
Subtract 859 from 1550 to get 691.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6910, and continue the process.

On to step 10:
If we divide 6910 by 859, we get 8 and a remainder of 38.
The next digit of our result is 8. 
Result so far: 63144.18
Deduct 6872 from 6910 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 11:
When dividing 380 by 859, we get 0 with a remainder of 380.
Record the quotient 0 as the next digit in the result. 
Result so far: 63144.18
If we take 0 away from 380, we end up with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Going ahead to step 12:
When dividing 3800 by 859, we get 4 with a remainder of 364.
Write down 4 as next digit of the result. 
Result so far: 63144.1804
If we subtract 3436 from 3800, we get 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Advancing to step 13:
859 goes into 3640 4 times with a remainder of 204.
Put 4 as the next digit of the answer. 
Result so far: 63144.18044
If we subtract 3436 from 3640, we get 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Our division results in 63144.18044 with a remaining 0.000204.
