Let's divide 30285439 by 397
We want to divide 30285439 by 397.

Moving on to step 1:
397 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 397

On to step 2:
If we divide 30 by 397, we get 0 and a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Bring next digit (2) of the dividend behind the 30 and repeat the process: 302 / 397

On to step 3:
397 goes into 302 0 times with a remainder of 302.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 302 and we're left with 302.
Take the next digit (8) from the dividend and append it to 302, then repeat: 3028 / 397

Step 4:
397 goes into 3028 7 times with a remainder of 249.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtracting 2779 from 3028 leaves us with 249.
Take the next digit (5) from the dividend and append it to 249, then repeat: 2495 / 397

On to step 5:
2495 divided by 397 is 6 with a remainder of 113.
The number 6 becomes the next digit in our result. 
Result so far: 76.0
Subtracting 2382 from 2495 leaves us with 113.
Grab the next digit (4) from the dividend, add it to 113, then carry on: 1134 / 397

Step 6:
The number 397 fits into 1134 2 times, leaving a remainder of 340.
The number 2 becomes the next digit in our result. 
Result so far: 762.0
Subtracting 794 from 1134 leaves us with 340.
Grab the next digit (3) from the dividend, add it to 340, then carry on: 3403 / 397

Step 7:
When dividing 3403 by 397, we get 8 with a remainder of 227.
Use 8 as the next digit of our solution. 
Result so far: 7628.0
Subtracting 3176 from 3403 leaves us with 227.
Include the next digit (9) from the dividend after 227, then repeat: 2279 / 397

Moving on to step 8:
397 goes into 2279 5 times with a remainder of 294.
The number 5 becomes the next digit in our result. 
Result so far: 76285.0
Subtract 1985 from 2279 to get 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Advancing to step 9:
If we divide 2940 by 397, we get 7 and a remainder of 161.
Put 7 as the next digit of the answer. 
Result so far: 76285.7
Subtract 2779 from 2940 to get 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

On to step 10:
When dividing 1610 by 397, we get 4 with a remainder of 22.
Put 4 as the next digit of the answer. 
Result so far: 76285.74
Deduct 1588 from 1610 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 11:
The number 397 fits into 220 0 times, leaving a remainder of 220.
Use 0 as the next digit of our solution. 
Result so far: 76285.74
If we take 0 away from 220, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Going ahead to step 12:
When dividing 2200 by 397, we get 5 with a remainder of 215.
Record the quotient 5 as the next digit in the result. 
Result so far: 76285.7405
Deduct 1985 from 2200 and we're left with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Let's proceed to step 13:
2150 divided by 397 is 5 with a remainder of 165.
Record the quotient 5 as the next digit in the result. 
Result so far: 76285.74055
Deduct 1985 from 2150 and we're left with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Our division results in 76285.74055 with a remaining 0.000165.
