Let's divide 30297997 by 86
We want to divide 30297997 by 86.

Moving on to step 1:
If we divide 3 by 86, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 86

Advancing to step 2:
86 goes into 30 0 times with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Fetch the next digit (2) from the dividend, attach it to 30 and continue: 302 / 86

On to step 3:
302 divided by 86 is 3 with a remainder of 44.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 258 from 302 and we're left with 44.
Fetch the next digit (9) from the dividend, attach it to 44 and continue: 449 / 86

Step 4:
When dividing 449 by 86, we get 5 with a remainder of 19.
Record the quotient 5 as the next digit in the result. 
Result so far: 35.0
If we take 430 away from 449, we end up with 19.
Append the next digit (7) from the dividend to 19 and continue with: 197 / 86

Moving on to step 5:
197 divided by 86 is 2 with a remainder of 25.
Record the quotient 2 as the next digit in the result. 
Result so far: 352.0
The remainder is 25 after subtracting 172 from 197.
Grab the next digit (9) from the dividend, add it to 25, then carry on: 259 / 86

Moving on to step 6:
The number 86 fits into 259 3 times, leaving a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 3523.0
Deduct 258 from 259 and we're left with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 86

On to step 7:
If we divide 19 by 86, we get 0 and a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 35230.0
Subtracting 0 from 19 leaves us with 19.
Append the next digit (7) from the dividend to 19 and continue with: 197 / 86

Going ahead to step 8:
86 can be fit into 197 2 times, resulting in a remainder of 25.
Record the quotient 2 as the next digit in the result. 
Result so far: 352302.0
If we take 172 away from 197, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 9:
The number 86 fits into 250 2 times, leaving a remainder of 78.
Write down 2 as next digit of the result. 
Result so far: 352302.2
If we take 172 away from 250, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Let's proceed to step 10:
If we divide 780 by 86, we get 9 and a remainder of 6.
Use 9 as the next digit of our solution. 
Result so far: 352302.29
Deduct 774 from 780 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 11:
86 goes into 60 0 times with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 352302.29
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 12:
The number 86 fits into 600 6 times, leaving a remainder of 84.
Record the quotient 6 as the next digit in the result. 
Result so far: 352302.2906
Subtracting 516 from 600 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

On to step 13:
86 can be fit into 840 9 times, resulting in a remainder of 66.
Use 9 as the next digit of our solution. 
Result so far: 352302.29069
Deduct 774 from 840 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 14:
The number 86 fits into 660 7 times, leaving a remainder of 58.
The number 7 becomes the next digit in our result. 
Result so far: 352302.290697
The remainder is 58 after subtracting 602 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 15:
86 can be fit into 580 6 times, resulting in a remainder of 64.
The next digit of our result is 6. 
Result so far: 352302.2906976
If we take 516 away from 580, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 16:
If we divide 640 by 86, we get 7 and a remainder of 38.
Write down 7 as next digit of the result. 
Result so far: 352302.29069767
Subtracting 602 from 640 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The final result is 352302.29069767 with a remainder of 3.8e-08.
