36451 ÷ 51 
We want to figure out the number of times 36451 can be divided by 51.

Moving on to step 1:
If we divide 3 by 51, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 51

Moving on to step 2:
The number 51 fits into 36 0 times, leaving a remainder of 36.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 36 and we're left with 36.
Grab the next digit (4) from the dividend, add it to 36, then carry on: 364 / 51

Moving on to step 3:
The number 51 fits into 364 7 times, leaving a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtracting 357 from 364 leaves us with 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 51

Moving on to step 4:
When dividing 75 by 51, we get 1 with a remainder of 24.
Put 1 as the next digit of the answer. 
Result so far: 71.0
If we subtract 51 from 75, we get 24.
Fetch the next digit (1) from the dividend, attach it to 24 and continue: 241 / 51

Advancing to step 5:
When dividing 241 by 51, we get 4 with a remainder of 37.
Put 4 as the next digit of the answer. 
Result so far: 714.0
If we take 204 away from 241, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 6:
51 goes into 370 7 times with a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 714.7
If we subtract 357 from 370, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 7:
When dividing 130 by 51, we get 2 with a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 714.72
Subtracting 102 from 130 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 8:
The number 51 fits into 280 5 times, leaving a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 714.725
The remainder is 25 after subtracting 255 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 9:
The number 51 fits into 250 4 times, leaving a remainder of 46.
Write down 4 as next digit of the result. 
Result so far: 714.7254
Subtracting 204 from 250 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 10:
The number 51 fits into 460 9 times, leaving a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 714.72549
If we take 459 away from 460, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 11:
10 divided by 51 is 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 714.72549
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 12:
When dividing 100 by 51, we get 1 with a remainder of 49.
Put 1 as the next digit of the answer. 
Result so far: 714.7254901
The remainder is 49 after subtracting 51 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 13:
When dividing 490 by 51, we get 9 with a remainder of 31.
The next digit of our result is 9. 
Result so far: 714.72549019
If we subtract 459 from 490, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

The final outcome is 714.72549019, with a leftover of 3.1e-08.
