687534 divided by 451 
We want to figure out the number of times 687534 can be divided by 451.

Moving on to step 1:
451 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 451

Going ahead to step 2:
451 can be fit into 68 0 times, resulting in a remainder of 68.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 68, we end up with 68.
Grab the next digit (7) from the dividend, add it to 68, then carry on: 687 / 451

Let's proceed to step 3:
451 goes into 687 1 times with a remainder of 236.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 451 from 687 to get 236.
Grab the next digit (5) from the dividend, add it to 236, then carry on: 2365 / 451

On to step 4:
If we divide 2365 by 451, we get 5 and a remainder of 110.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we subtract 2255 from 2365, we get 110.
Append the next digit (3) from the dividend to 110 and continue with: 1103 / 451

Advancing to step 5:
When dividing 1103 by 451, we get 2 with a remainder of 201.
Write down 2 as next digit of the result. 
Result so far: 152.0
Deduct 902 from 1103 and we're left with 201.
Take the next digit (4) from the dividend and append it to 201, then repeat: 2014 / 451

On to step 6:
451 goes into 2014 4 times with a remainder of 210.
The next digit of our result is 4. 
Result so far: 1524.0
If we subtract 1804 from 2014, we get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Going ahead to step 7:
The number 451 fits into 2100 4 times, leaving a remainder of 296.
The number 4 becomes the next digit in our result. 
Result so far: 1524.4
Subtracting 1804 from 2100 leaves us with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Let's proceed to step 8:
451 goes into 2960 6 times with a remainder of 254.
The number 6 becomes the next digit in our result. 
Result so far: 1524.46
Subtracting 2706 from 2960 leaves us with 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Advancing to step 9:
When dividing 2540 by 451, we get 5 with a remainder of 285.
The next digit of our result is 5. 
Result so far: 1524.465
If we take 2255 away from 2540, we end up with 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Let's proceed to step 10:
451 goes into 2850 6 times with a remainder of 144.
The number 6 becomes the next digit in our result. 
Result so far: 1524.4656
If we subtract 2706 from 2850, we get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Let's proceed to step 11:
When dividing 1440 by 451, we get 3 with a remainder of 87.
The number 3 becomes the next digit in our result. 
Result so far: 1524.46563
If we subtract 1353 from 1440, we get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Moving on to step 12:
The number 451 fits into 870 1 times, leaving a remainder of 419.
Record the quotient 1 as the next digit in the result. 
Result so far: 1524.465631
Subtracting 451 from 870 leaves us with 419.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4190, and continue the process.

Let's proceed to step 13:
4190 divided by 451 is 9 with a remainder of 131.
The next digit of our result is 9. 
Result so far: 1524.4656319
Subtract 4059 from 4190 to get 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Moving on to step 14:
When dividing 1310 by 451, we get 2 with a remainder of 408.
The next digit of our result is 2. 
Result so far: 1524.46563192
Subtracting 902 from 1310 leaves us with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

The final outcome is 1524.46563192, with a leftover of 4.08e-07.
