146138 divided by 20 
Let's see how many times 20 fits into 146138.

Going ahead to step 1:
1 divided by 20 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 20

On to step 2:
20 goes into 14 0 times with a remainder of 14.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 14 and we're left with 14.
Include the next digit (6) from the dividend after 14, then repeat: 146 / 20

Going ahead to step 3:
20 goes into 146 7 times with a remainder of 6.
The next digit of our result is 7. 
Result so far: 7.0
Deduct 140 from 146 and we're left with 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 20

Let's proceed to step 4:
If we divide 61 by 20, we get 3 and a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 73.0
Deduct 60 from 61 and we're left with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 20

Step 5:
The number 20 fits into 13 0 times, leaving a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 730.0
The remainder is 13 after subtracting 0 from 13.
Grab the next digit (8) from the dividend, add it to 13, then carry on: 138 / 20

Moving on to step 6:
138 divided by 20 is 6 with a remainder of 18.
Write down 6 as next digit of the result. 
Result so far: 7306.0
Subtract 120 from 138 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 7:
180 divided by 20 is 9 with a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 7306.9
Deduct 180 from 180 and we're left 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.

On to step 8:
If we divide 0 by 20, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 7306.9
Subtracting 0 from 0 leaves us 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.

Let's proceed to step 9:
0 divided by 20 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 7306.9
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.

Our division results in 7306.9 with a remaining 0.0.
