30287389 ÷ 451 
We're looking to find how many times 451 goes into 30287389.

On to step 1:
The number 451 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 451

On to step 2:
The number 451 fits into 30 0 times, leaving a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 30 leaves us with 30.
Fetch the next digit (2) from the dividend, attach it to 30 and continue: 302 / 451

On to step 3:
451 goes into 302 0 times with a remainder of 302.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 302 leaves us with 302.
Include the next digit (8) from the dividend after 302, then repeat: 3028 / 451

On to step 4:
When dividing 3028 by 451, we get 6 with a remainder of 322.
Use 6 as the next digit of our solution. 
Result so far: 6.0
The remainder is 322 after subtracting 2706 from 3028.
Grab the next digit (7) from the dividend, add it to 322, then carry on: 3227 / 451

Step 5:
When dividing 3227 by 451, we get 7 with a remainder of 70.
The number 7 becomes the next digit in our result. 
Result so far: 67.0
Deduct 3157 from 3227 and we're left with 70.
Fetch the next digit (3) from the dividend, attach it to 70 and continue: 703 / 451

On to step 6:
If we divide 703 by 451, we get 1 and a remainder of 252.
Record the quotient 1 as the next digit in the result. 
Result so far: 671.0
If we subtract 451 from 703, we get 252.
Grab the next digit (8) from the dividend, add it to 252, then carry on: 2528 / 451

Step 7:
The number 451 fits into 2528 5 times, leaving a remainder of 273.
Use 5 as the next digit of our solution. 
Result so far: 6715.0
Subtract 2255 from 2528 to get 273.
Fetch the next digit (9) from the dividend, attach it to 273 and continue: 2739 / 451

Going ahead to step 8:
The number 451 fits into 2739 6 times, leaving a remainder of 33.
The next digit of our result is 6. 
Result so far: 67156.0
If we subtract 2706 from 2739, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 9:
451 can be fit into 330 0 times, resulting in a remainder of 330.
Record the quotient 0 as the next digit in the result. 
Result so far: 67156.0
If we take 0 away from 330, we end up with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Step 10:
The number 451 fits into 3300 7 times, leaving a remainder of 143.
Use 7 as the next digit of our solution. 
Result so far: 67156.07
If we subtract 3157 from 3300, we get 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Going ahead to step 11:
1430 divided by 451 is 3 with a remainder of 77.
Put 3 as the next digit of the answer. 
Result so far: 67156.073
Deduct 1353 from 1430 and we're left with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

On to step 12:
451 can be fit into 770 1 times, resulting in a remainder of 319.
Put 1 as the next digit of the answer. 
Result so far: 67156.0731
Subtract 451 from 770 to get 319.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3190, and continue the process.

Advancing to step 13:
The number 451 fits into 3190 7 times, leaving a remainder of 33.
The next digit of our result is 7. 
Result so far: 67156.07317
Subtracting 3157 from 3190 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 14:
The number 451 fits into 330 0 times, leaving a remainder of 330.
Write down 0 as next digit of the result. 
Result so far: 67156.07317
The remainder is 330 after subtracting 0 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Let's proceed to step 15:
3300 divided by 451 is 7 with a remainder of 143.
Record the quotient 7 as the next digit in the result. 
Result so far: 67156.0731707
Subtract 3157 from 3300 to get 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Advancing to step 16:
If we divide 1430 by 451, we get 3 and a remainder of 77.
The next digit of our result is 3. 
Result so far: 67156.07317073
Deduct 1353 from 1430 and we're left with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

After the division, we end up with 67156.07317073 and a remainder of 7.7e-08.
