Let's divide 18648357 by 859
Let's see how many times 859 fits into 18648357.

Moving on to step 1:
859 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 859

On to step 2:
859 can be fit into 18 0 times, resulting in a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 18 and we're left with 18.
Append the next digit (6) from the dividend to 18 and continue with: 186 / 859

Going ahead to step 3:
186 divided by 859 is 0 with a remainder of 186.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 186 after subtracting 0 from 186.
Append the next digit (4) from the dividend to 186 and continue with: 1864 / 859

On to step 4:
When dividing 1864 by 859, we get 2 with a remainder of 146.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 1718 from 1864, we get 146.
Bring next digit (8) of the dividend behind the 146 and repeat the process: 1468 / 859

Advancing to step 5:
859 goes into 1468 1 times with a remainder of 609.
The next digit of our result is 1. 
Result so far: 21.0
Subtract 859 from 1468 to get 609.
Fetch the next digit (3) from the dividend, attach it to 609 and continue: 6093 / 859

Going ahead to step 6:
859 can be fit into 6093 7 times, resulting in a remainder of 80.
Write down 7 as next digit of the result. 
Result so far: 217.0
If we subtract 6013 from 6093, we get 80.
Fetch the next digit (5) from the dividend, attach it to 80 and continue: 805 / 859

Going ahead to step 7:
If we divide 805 by 859, we get 0 and a remainder of 805.
Record the quotient 0 as the next digit in the result. 
Result so far: 2170.0
If we subtract 0 from 805, we get 805.
Include the next digit (7) from the dividend after 805, then repeat: 8057 / 859

Step 8:
If we divide 8057 by 859, we get 9 and a remainder of 326.
Record the quotient 9 as the next digit in the result. 
Result so far: 21709.0
If we take 7731 away from 8057, we end up with 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Step 9:
3260 divided by 859 is 3 with a remainder of 683.
Use 3 as the next digit of our solution. 
Result so far: 21709.3
Subtract 2577 from 3260 to get 683.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6830, and continue the process.

On to step 10:
When dividing 6830 by 859, we get 7 with a remainder of 817.
Use 7 as the next digit of our solution. 
Result so far: 21709.37
Subtract 6013 from 6830 to get 817.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8170, and continue the process.

On to step 11:
859 can be fit into 8170 9 times, resulting in a remainder of 439.
The number 9 becomes the next digit in our result. 
Result so far: 21709.379
Subtract 7731 from 8170 to get 439.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4390, and continue the process.

Going ahead to step 12:
The number 859 fits into 4390 5 times, leaving a remainder of 95.
Record the quotient 5 as the next digit in the result. 
Result so far: 21709.3795
If we subtract 4295 from 4390, we get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Advancing to step 13:
950 divided by 859 is 1 with a remainder of 91.
The next digit of our result is 1. 
Result so far: 21709.37951
If we take 859 away from 950, we end up with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

On to step 14:
859 can be fit into 910 1 times, resulting in a remainder of 51.
Write down 1 as next digit of the result. 
Result so far: 21709.379511
If we take 859 away from 910, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

The final result is 21709.379511 with a remainder of 5.1e-06.
