837457 ÷ 20 
We want to divide 837457 by 20.

On to step 1:
If we divide 8 by 20, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 20

On to step 2:
83 divided by 20 is 4 with a remainder of 3.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 80 from 83 to get 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 20

Step 3:
The number 20 fits into 37 1 times, leaving a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 41.0
Subtract 20 from 37 to get 17.
Bring next digit (4) of the dividend behind the 17 and repeat the process: 174 / 20

Going ahead to step 4:
20 goes into 174 8 times with a remainder of 14.
The number 8 becomes the next digit in our result. 
Result so far: 418.0
Subtract 160 from 174 to get 14.
Grab the next digit (5) from the dividend, add it to 14, then carry on: 145 / 20

Moving on to step 5:
20 goes into 145 7 times with a remainder of 5.
Use 7 as the next digit of our solution. 
Result so far: 4187.0
The remainder is 5 after subtracting 140 from 145.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 20

Let's proceed to step 6:
The number 20 fits into 57 2 times, leaving a remainder of 17.
Put 2 as the next digit of the answer. 
Result so far: 41872.0
Subtracting 40 from 57 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 7:
20 can be fit into 170 8 times, resulting in a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 41872.8
The remainder is 10 after subtracting 160 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
The number 20 fits into 100 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 41872.85
If we subtract 100 from 100, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
20 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 41872.85
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
20 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 41872.85
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 41872.85, with a leftover of 0.0.
