We're dividing 139499 by 453 
Let's see how many times 453 fits into 139499.

Moving on to step 1:
The number 453 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 453

Going ahead to step 2:
The number 453 fits into 13 0 times, leaving a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Grab the next digit (9) from the dividend, add it to 13, then carry on: 139 / 453

Going ahead to step 3:
When dividing 139 by 453, we get 0 with a remainder of 139.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 139 and we're left with 139.
Append the next digit (4) from the dividend to 139 and continue with: 1394 / 453

Let's proceed to step 4:
1394 divided by 453 is 3 with a remainder of 35.
The next digit of our result is 3. 
Result so far: 3.0
If we take 1359 away from 1394, we end up with 35.
Include the next digit (9) from the dividend after 35, then repeat: 359 / 453

Going ahead to step 5:
If we divide 359 by 453, we get 0 and a remainder of 359.
Use 0 as the next digit of our solution. 
Result so far: 30.0
Subtract 0 from 359 to get 359.
Fetch the next digit (9) from the dividend, attach it to 359 and continue: 3599 / 453

Let's proceed to step 6:
When dividing 3599 by 453, we get 7 with a remainder of 428.
Use 7 as the next digit of our solution. 
Result so far: 307.0
If we subtract 3171 from 3599, we get 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

On to step 7:
The number 453 fits into 4280 9 times, leaving a remainder of 203.
Write down 9 as next digit of the result. 
Result so far: 307.9
Subtract 4077 from 4280 to get 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Advancing to step 8:
The number 453 fits into 2030 4 times, leaving a remainder of 218.
Use 4 as the next digit of our solution. 
Result so far: 307.94
Deduct 1812 from 2030 and we're left with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Step 9:
When dividing 2180 by 453, we get 4 with a remainder of 368.
The number 4 becomes the next digit in our result. 
Result so far: 307.944
If we take 1812 away from 2180, we end up with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

In conclusion, the division gives 307.944 with a balance of 0.0368.
