Let's divide 30973977 by 145
Our goal is to divide 30973977 by 145.

Advancing to step 1:
3 divided by 145 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 145

Moving on to step 2:
If we divide 30 by 145, we get 0 and a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Append the next digit (9) from the dividend to 30 and continue with: 309 / 145

On to step 3:
When dividing 309 by 145, we get 2 with a remainder of 19.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 19 after subtracting 290 from 309.
Include the next digit (7) from the dividend after 19, then repeat: 197 / 145

Step 4:
When dividing 197 by 145, we get 1 with a remainder of 52.
Put 1 as the next digit of the answer. 
Result so far: 21.0
Subtracting 145 from 197 leaves us with 52.
Fetch the next digit (3) from the dividend, attach it to 52 and continue: 523 / 145

Moving on to step 5:
145 goes into 523 3 times with a remainder of 88.
Put 3 as the next digit of the answer. 
Result so far: 213.0
If we take 435 away from 523, we end up with 88.
Bring next digit (9) of the dividend behind the 88 and repeat the process: 889 / 145

Let's proceed to step 6:
The number 145 fits into 889 6 times, leaving a remainder of 19.
Write down 6 as next digit of the result. 
Result so far: 2136.0
Subtracting 870 from 889 leaves us with 19.
Bring next digit (7) of the dividend behind the 19 and repeat the process: 197 / 145

Going ahead to step 7:
145 goes into 197 1 times with a remainder of 52.
The number 1 becomes the next digit in our result. 
Result so far: 21361.0
The remainder is 52 after subtracting 145 from 197.
Take the next digit (7) from the dividend and append it to 52, then repeat: 527 / 145

On to step 8:
The number 145 fits into 527 3 times, leaving a remainder of 92.
Write down 3 as next digit of the result. 
Result so far: 213613.0
Deduct 435 from 527 and we're left with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Moving on to step 9:
The number 145 fits into 920 6 times, leaving a remainder of 50.
Record the quotient 6 as the next digit in the result. 
Result so far: 213613.6
If we take 870 away from 920, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 10:
500 divided by 145 is 3 with a remainder of 65.
Write down 3 as next digit of the result. 
Result so far: 213613.63
If we take 435 away from 500, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 11:
The number 145 fits into 650 4 times, leaving a remainder of 70.
The next digit of our result is 4. 
Result so far: 213613.634
Deduct 580 from 650 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 12:
When dividing 700 by 145, we get 4 with a remainder of 120.
Write down 4 as next digit of the result. 
Result so far: 213613.6344
The remainder is 120 after subtracting 580 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Our division results in 213613.6344 with a remaining 0.0012.
