Let's divide 30420247 by 389
We want to divide 30420247 by 389.

On to step 1:
389 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 389

Let's proceed to step 2:
If we divide 30 by 389, we get 0 and a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Bring next digit (4) of the dividend behind the 30 and repeat the process: 304 / 389

On to step 3:
389 can be fit into 304 0 times, resulting in a remainder of 304.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 304 and we're left with 304.
Bring next digit (2) of the dividend behind the 304 and repeat the process: 3042 / 389

Let's proceed to step 4:
If we divide 3042 by 389, we get 7 and a remainder of 319.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtract 2723 from 3042 to get 319.
Take the next digit (0) from the dividend and append it to 319, then repeat: 3190 / 389

Moving on to step 5:
If we divide 3190 by 389, we get 8 and a remainder of 78.
Write down 8 as next digit of the result. 
Result so far: 78.0
Subtract 3112 from 3190 to get 78.
Append the next digit (2) from the dividend to 78 and continue with: 782 / 389

Step 6:
When dividing 782 by 389, we get 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 782.0
Subtract 778 from 782 to get 4.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 389

Step 7:
The number 389 fits into 44 0 times, leaving a remainder of 44.
The next digit of our result is 0. 
Result so far: 7820.0
If we subtract 0 from 44, we get 44.
Grab the next digit (7) from the dividend, add it to 44, then carry on: 447 / 389

Going ahead to step 8:
When dividing 447 by 389, we get 1 with a remainder of 58.
Write down 1 as next digit of the result. 
Result so far: 78201.0
If we take 389 away from 447, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 9:
389 can be fit into 580 1 times, resulting in a remainder of 191.
Write down 1 as next digit of the result. 
Result so far: 78201.1
Deduct 389 from 580 and we're left with 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

Let's proceed to step 10:
If we divide 1910 by 389, we get 4 and a remainder of 354.
Use 4 as the next digit of our solution. 
Result so far: 78201.14
Subtract 1556 from 1910 to get 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Step 11:
When dividing 3540 by 389, we get 9 with a remainder of 39.
Record the quotient 9 as the next digit in the result. 
Result so far: 78201.149
Subtracting 3501 from 3540 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 12:
When dividing 390 by 389, we get 1 with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 78201.1491
Deduct 389 from 390 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 13:
The number 389 fits into 10 0 times, leaving a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 78201.1491
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 14:
If we divide 100 by 389, we get 0 and a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 78201.1491
Subtract 0 from 100 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final result is 78201.1491 with a remainder of 1e-05.
