Let's divide 30431956 by 978
Our goal is to divide 30431956 by 978.

Moving on to step 1:
The number 978 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 978

Moving on to step 2:
978 can be fit into 30 0 times, resulting in a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 30, we get 30.
Fetch the next digit (4) from the dividend, attach it to 30 and continue: 304 / 978

Going ahead to step 3:
If we divide 304 by 978, we get 0 and a remainder of 304.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 304 and we're left with 304.
Include the next digit (3) from the dividend after 304, then repeat: 3043 / 978

Advancing to step 4:
When dividing 3043 by 978, we get 3 with a remainder of 109.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 2934 from 3043 and we're left with 109.
Take the next digit (1) from the dividend and append it to 109, then repeat: 1091 / 978

Let's proceed to step 5:
978 goes into 1091 1 times with a remainder of 113.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
Subtract 978 from 1091 to get 113.
Bring next digit (9) of the dividend behind the 113 and repeat the process: 1139 / 978

Let's proceed to step 6:
If we divide 1139 by 978, we get 1 and a remainder of 161.
Write down 1 as next digit of the result. 
Result so far: 311.0
Subtract 978 from 1139 to get 161.
Bring next digit (5) of the dividend behind the 161 and repeat the process: 1615 / 978

Step 7:
978 goes into 1615 1 times with a remainder of 637.
Record the quotient 1 as the next digit in the result. 
Result so far: 3111.0
The remainder is 637 after subtracting 978 from 1615.
Bring next digit (6) of the dividend behind the 637 and repeat the process: 6376 / 978

On to step 8:
978 goes into 6376 6 times with a remainder of 508.
The number 6 becomes the next digit in our result. 
Result so far: 31116.0
The remainder is 508 after subtracting 5868 from 6376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

On to step 9:
The number 978 fits into 5080 5 times, leaving a remainder of 190.
The next digit of our result is 5. 
Result so far: 31116.5
If we take 4890 away from 5080, we end up with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

On to step 10:
978 goes into 1900 1 times with a remainder of 922.
The next digit of our result is 1. 
Result so far: 31116.51
If we take 978 away from 1900, we end up with 922.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9220, and continue the process.

Let's proceed to step 11:
If we divide 9220 by 978, we get 9 and a remainder of 418.
Use 9 as the next digit of our solution. 
Result so far: 31116.519
If we take 8802 away from 9220, we end up with 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Advancing to step 12:
4180 divided by 978 is 4 with a remainder of 268.
The number 4 becomes the next digit in our result. 
Result so far: 31116.5194
If we subtract 3912 from 4180, we get 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Step 13:
If we divide 2680 by 978, we get 2 and a remainder of 724.
Write down 2 as next digit of the result. 
Result so far: 31116.51942
If we subtract 1956 from 2680, we get 724.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7240, and continue the process.

On to step 14:
978 goes into 7240 7 times with a remainder of 394.
Put 7 as the next digit of the answer. 
Result so far: 31116.519427
The remainder is 394 after subtracting 6846 from 7240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

On to step 15:
3940 divided by 978 is 4 with a remainder of 28.
Use 4 as the next digit of our solution. 
Result so far: 31116.5194274
If we take 3912 away from 3940, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 16:
978 goes into 280 0 times with a remainder of 280.
Record the quotient 0 as the next digit in the result. 
Result so far: 31116.5194274
Deduct 0 from 280 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

The final result is 31116.5194274 with a remainder of 2.8e-07.
