We're dividing 30964779 by 397 
Our goal is to divide 30964779 by 397.

Step 1:
If we divide 3 by 397, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 397

Advancing to step 2:
30 divided by 397 is 0 with a remainder of 30.
Write down 0 as next digit of 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 / 397

Let's proceed to step 3:
When dividing 309 by 397, we get 0 with a remainder of 309.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 309, we get 309.
Take the next digit (6) from the dividend and append it to 309, then repeat: 3096 / 397

Going ahead to step 4:
397 can be fit into 3096 7 times, resulting in a remainder of 317.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 2779 from 3096 and we're left with 317.
Take the next digit (4) from the dividend and append it to 317, then repeat: 3174 / 397

Going ahead to step 5:
When dividing 3174 by 397, we get 7 with a remainder of 395.
Put 7 as the next digit of the answer. 
Result so far: 77.0
The remainder is 395 after subtracting 2779 from 3174.
Fetch the next digit (7) from the dividend, attach it to 395 and continue: 3957 / 397

On to step 6:
397 can be fit into 3957 9 times, resulting in a remainder of 384.
Put 9 as the next digit of the answer. 
Result so far: 779.0
The remainder is 384 after subtracting 3573 from 3957.
Grab the next digit (7) from the dividend, add it to 384, then carry on: 3847 / 397

Step 7:
If we divide 3847 by 397, we get 9 and a remainder of 274.
Write down 9 as next digit of the result. 
Result so far: 7799.0
The remainder is 274 after subtracting 3573 from 3847.
Fetch the next digit (9) from the dividend, attach it to 274 and continue: 2749 / 397

Advancing to step 8:
397 goes into 2749 6 times with a remainder of 367.
The number 6 becomes the next digit in our result. 
Result so far: 77996.0
Deduct 2382 from 2749 and we're left with 367.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3670, and continue the process.

Moving on to step 9:
397 goes into 3670 9 times with a remainder of 97.
Use 9 as the next digit of our solution. 
Result so far: 77996.9
The remainder is 97 after subtracting 3573 from 3670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Step 10:
397 can be fit into 970 2 times, resulting in a remainder of 176.
The next digit of our result is 2. 
Result so far: 77996.92
Deduct 794 from 970 and we're left with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Advancing to step 11:
397 can be fit into 1760 4 times, resulting in a remainder of 172.
Write down 4 as next digit of the result. 
Result so far: 77996.924
If we subtract 1588 from 1760, we get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

On to step 12:
397 goes into 1720 4 times with a remainder of 132.
Use 4 as the next digit of our solution. 
Result so far: 77996.9244
Subtracting 1588 from 1720 leaves us with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

In conclusion, the division gives 77996.9244 with a balance of 0.00132.
