68007660 ÷ 453 
Let's see how many times 453 fits into 68007660.

On to step 1:
The number 453 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 453

Going ahead to step 2:
The number 453 fits into 68 0 times, leaving a remainder of 68.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 68, we get 68.
Bring next digit (0) of the dividend behind the 68 and repeat the process: 680 / 453

Going ahead to step 3:
When dividing 680 by 453, we get 1 with a remainder of 227.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 453 from 680 leaves us with 227.
Include the next digit (0) from the dividend after 227, then repeat: 2270 / 453

Advancing to step 4:
When dividing 2270 by 453, we get 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we take 2265 away from 2270, we end up with 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 453

Let's proceed to step 5:
If we divide 57 by 453, we get 0 and a remainder of 57.
Record the quotient 0 as the next digit in the result. 
Result so far: 150.0
Subtracting 0 from 57 leaves us with 57.
Fetch the next digit (6) from the dividend, attach it to 57 and continue: 576 / 453

On to step 6:
576 divided by 453 is 1 with a remainder of 123.
The number 1 becomes the next digit in our result. 
Result so far: 1501.0
The remainder is 123 after subtracting 453 from 576.
Include the next digit (6) from the dividend after 123, then repeat: 1236 / 453

Step 7:
When dividing 1236 by 453, we get 2 with a remainder of 330.
Put 2 as the next digit of the answer. 
Result so far: 15012.0
If we take 906 away from 1236, we end up with 330.
Take the next digit (0) from the dividend and append it to 330, then repeat: 3300 / 453

Going ahead to step 8:
When dividing 3300 by 453, we get 7 with a remainder of 129.
Use 7 as the next digit of our solution. 
Result so far: 150127.0
If we subtract 3171 from 3300, we get 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

Advancing to step 9:
453 goes into 1290 2 times with a remainder of 384.
Put 2 as the next digit of the answer. 
Result so far: 150127.2
If we subtract 906 from 1290, we get 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Let's proceed to step 10:
3840 divided by 453 is 8 with a remainder of 216.
The number 8 becomes the next digit in our result. 
Result so far: 150127.28
Subtract 3624 from 3840 to get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Step 11:
The number 453 fits into 2160 4 times, leaving a remainder of 348.
Use 4 as the next digit of our solution. 
Result so far: 150127.284
Subtract 1812 from 2160 to get 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Advancing to step 12:
If we divide 3480 by 453, we get 7 and a remainder of 309.
The next digit of our result is 7. 
Result so far: 150127.2847
The remainder is 309 after subtracting 3171 from 3480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

Step 13:
453 goes into 3090 6 times with a remainder of 372.
The next digit of our result is 6. 
Result so far: 150127.28476
If we subtract 2718 from 3090, we get 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Advancing to step 14:
If we divide 3720 by 453, we get 8 and a remainder of 96.
Record the quotient 8 as the next digit in the result. 
Result so far: 150127.284768
The remainder is 96 after subtracting 3624 from 3720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

On to step 15:
The number 453 fits into 960 2 times, leaving a remainder of 54.
The next digit of our result is 2. 
Result so far: 150127.2847682
If we subtract 906 from 960, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 16:
453 goes into 540 1 times with a remainder of 87.
Use 1 as the next digit of our solution. 
Result so far: 150127.28476821
Deduct 453 from 540 and we're left with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

The quotient of the division is 150127.28476821, and the remainder is 8.7e-08.
