148495 divided by 21 
We're looking to find how many times 21 goes into 148495.

Let's proceed to step 1:
When dividing 1 by 21, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 21

Step 2:
14 divided by 21 is 0 with a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 14 to get 14.
Take the next digit (8) from the dividend and append it to 14, then repeat: 148 / 21

Let's proceed to step 3:
The number 21 fits into 148 7 times, leaving a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 7.0
Deduct 147 from 148 and we're left with 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 21

Advancing to step 4:
If we divide 14 by 21, we get 0 and a remainder of 14.
The next digit of our result is 0. 
Result so far: 70.0
Subtract 0 from 14 to get 14.
Include the next digit (9) from the dividend after 14, then repeat: 149 / 21

Advancing to step 5:
149 divided by 21 is 7 with a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 707.0
If we take 147 away from 149, we end up with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 21

Let's proceed to step 6:
When dividing 25 by 21, we get 1 with a remainder of 4.
The next digit of our result is 1. 
Result so far: 7071.0
Subtract 21 from 25 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 7:
If we divide 40 by 21, we get 1 and a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 7071.1
Deduct 21 from 40 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 8:
21 goes into 190 9 times with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 7071.19
If we take 189 away from 190, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 9:
If we divide 10 by 21, we get 0 and a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 7071.19
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 10:
21 goes into 100 4 times with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 7071.1904
If we take 84 away from 100, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 11:
If we divide 160 by 21, we get 7 and a remainder of 13.
The next digit of our result is 7. 
Result so far: 7071.19047
If we take 147 away from 160, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 12:
When dividing 130 by 21, we get 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 7071.190476
Subtracting 126 from 130 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 13:
If we divide 40 by 21, we get 1 and a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 7071.1904761
Deduct 21 from 40 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 14:
21 can be fit into 190 9 times, resulting in a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 7071.19047619
Subtracting 189 from 190 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

After the division, we end up with 7071.19047619 and a remainder of 1e-09.
