Let's divide 75398691 by 306
We want to figure out the number of times 75398691 can be divided by 306.

On to step 1:
If we divide 7 by 306, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 306

Step 2:
75 divided by 306 is 0 with a remainder of 75.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 75, we get 75.
Include the next digit (3) from the dividend after 75, then repeat: 753 / 306

Moving on to step 3:
If we divide 753 by 306, we get 2 and a remainder of 141.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 612 from 753 leaves us with 141.
Take the next digit (9) from the dividend and append it to 141, then repeat: 1419 / 306

Advancing to step 4:
The number 306 fits into 1419 4 times, leaving a remainder of 195.
Record the quotient 4 as the next digit in the result. 
Result so far: 24.0
The remainder is 195 after subtracting 1224 from 1419.
Take the next digit (8) from the dividend and append it to 195, then repeat: 1958 / 306

Let's proceed to step 5:
The number 306 fits into 1958 6 times, leaving a remainder of 122.
Put 6 as the next digit of the answer. 
Result so far: 246.0
If we subtract 1836 from 1958, we get 122.
Append the next digit (6) from the dividend to 122 and continue with: 1226 / 306

On to step 6:
If we divide 1226 by 306, we get 4 and a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 2464.0
Subtracting 1224 from 1226 leaves us with 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 306

Going ahead to step 7:
29 divided by 306 is 0 with a remainder of 29.
Write down 0 as next digit of the result. 
Result so far: 24640.0
Deduct 0 from 29 and we're left with 29.
Fetch the next digit (1) from the dividend, attach it to 29 and continue: 291 / 306

Step 8:
If we divide 291 by 306, we get 0 and a remainder of 291.
Record the quotient 0 as the next digit in the result. 
Result so far: 246400.0
Deduct 0 from 291 and we're left with 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

Let's proceed to step 9:
306 goes into 2910 9 times with a remainder of 156.
The next digit of our result is 9. 
Result so far: 246400.9
If we take 2754 away from 2910, we end up with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Let's proceed to step 10:
When dividing 1560 by 306, we get 5 with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 246400.95
Subtract 1530 from 1560 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 11:
300 divided by 306 is 0 with a remainder of 300.
The next digit of our result is 0. 
Result so far: 246400.95
Subtracting 0 from 300 leaves us with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

On to step 12:
The number 306 fits into 3000 9 times, leaving a remainder of 246.
The number 9 becomes the next digit in our result. 
Result so far: 246400.9509
If we take 2754 away from 3000, we end up with 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Let's proceed to step 13:
If we divide 2460 by 306, we get 8 and a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 246400.95098
If we subtract 2448 from 2460, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 14:
306 goes into 120 0 times with a remainder of 120.
Put 0 as the next digit of the answer. 
Result so far: 246400.95098
The remainder is 120 after subtracting 0 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 15:
1200 divided by 306 is 3 with a remainder of 282.
Put 3 as the next digit of the answer. 
Result so far: 246400.9509803
The remainder is 282 after subtracting 918 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Going ahead to step 16:
If we divide 2820 by 306, we get 9 and a remainder of 66.
The number 9 becomes the next digit in our result. 
Result so far: 246400.95098039
The remainder is 66 after subtracting 2754 from 2820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

After the division, we end up with 246400.95098039 and a remainder of 6.6e-08.
