We're dividing 149299 by 21 
We're looking to find how many times 21 goes into 149299.

Advancing to step 1:
1 divided by 21 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 21

Going ahead to step 2:
21 goes into 14 0 times with a remainder of 14.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 14 leaves us with 14.
Grab the next digit (9) from the dividend, add it to 14, then carry on: 149 / 21

On to step 3:
21 goes into 149 7 times with a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 147 from 149 and we're left with 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 21

Let's proceed to step 4:
21 goes into 22 1 times with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 71.0
Subtract 21 from 22 to get 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 21

Let's proceed to step 5:
The number 21 fits into 19 0 times, leaving a remainder of 19.
The next digit of our result is 0. 
Result so far: 710.0
If we subtract 0 from 19, we get 19.
Fetch the next digit (9) from the dividend, attach it to 19 and continue: 199 / 21

On to step 6:
21 can be fit into 199 9 times, resulting in a remainder of 10.
Use 9 as the next digit of our solution. 
Result so far: 7109.0
Subtract 189 from 199 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 7:
If we divide 100 by 21, we get 4 and a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 7109.4
Subtract 84 from 100 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 8:
160 divided by 21 is 7 with a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 7109.47
The remainder is 13 after subtracting 147 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 9:
130 divided by 21 is 6 with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 7109.476
If we take 126 away from 130, we end up 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.

Step 10:
21 goes into 40 1 times with a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 7109.4761
Subtract 21 from 40 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 11:
21 can be fit into 190 9 times, resulting in a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 7109.47619
The remainder is 1 after subtracting 189 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 12:
If we divide 10 by 21, we get 0 and a remainder of 10.
The next digit of our result is 0. 
Result so far: 7109.47619
Subtract 0 from 10 to get 10.
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 13:
The number 21 fits into 100 4 times, leaving a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 7109.4761904
Subtracting 84 from 100 leaves us 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 14:
If we divide 160 by 21, we get 7 and a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 7109.47619047
The remainder is 13 after subtracting 147 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Our division results in 7109.47619047 with a remaining 1.3e-08.
