51373527 ÷ 665 
We want to divide 51373527 by 665.

Moving on to step 1:
The number 665 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 665

Advancing to step 2:
The number 665 fits into 51 0 times, leaving a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Fetch the next digit (3) from the dividend, attach it to 51 and continue: 513 / 665

Going ahead to step 3:
513 divided by 665 is 0 with a remainder of 513.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 513 to get 513.
Grab the next digit (7) from the dividend, add it to 513, then carry on: 5137 / 665

Going ahead to step 4:
When dividing 5137 by 665, we get 7 with a remainder of 482.
The next digit of our result is 7. 
Result so far: 7.0
If we take 4655 away from 5137, we end up with 482.
Bring next digit (3) of the dividend behind the 482 and repeat the process: 4823 / 665

Step 5:
665 can be fit into 4823 7 times, resulting in a remainder of 168.
Record the quotient 7 as the next digit in the result. 
Result so far: 77.0
Subtract 4655 from 4823 to get 168.
Grab the next digit (5) from the dividend, add it to 168, then carry on: 1685 / 665

Moving on to step 6:
1685 divided by 665 is 2 with a remainder of 355.
Use 2 as the next digit of our solution. 
Result so far: 772.0
Subtract 1330 from 1685 to get 355.
Include the next digit (2) from the dividend after 355, then repeat: 3552 / 665

Step 7:
If we divide 3552 by 665, we get 5 and a remainder of 227.
Use 5 as the next digit of our solution. 
Result so far: 7725.0
Deduct 3325 from 3552 and we're left with 227.
Grab the next digit (7) from the dividend, add it to 227, then carry on: 2277 / 665

Let's proceed to step 8:
The number 665 fits into 2277 3 times, leaving a remainder of 282.
The next digit of our result is 3. 
Result so far: 77253.0
Subtracting 1995 from 2277 leaves us with 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

On to step 9:
2820 divided by 665 is 4 with a remainder of 160.
The number 4 becomes the next digit in our result. 
Result so far: 77253.4
If we subtract 2660 from 2820, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 10:
665 can be fit into 1600 2 times, resulting in a remainder of 270.
The next digit of our result is 2. 
Result so far: 77253.42
Subtract 1330 from 1600 to get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Let's proceed to step 11:
When dividing 2700 by 665, we get 4 with a remainder of 40.
Put 4 as the next digit of the answer. 
Result so far: 77253.424
If we subtract 2660 from 2700, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 12:
The number 665 fits into 400 0 times, leaving a remainder of 400.
The next digit of our result is 0. 
Result so far: 77253.424
Deduct 0 from 400 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Going ahead to step 13:
665 goes into 4000 6 times with a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 77253.42406
Subtracting 3990 from 4000 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 14:
665 goes into 100 0 times with a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 77253.42406
Subtract 0 from 100 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 15:
When dividing 1000 by 665, we get 1 with a remainder of 335.
The next digit of our result is 1. 
Result so far: 77253.4240601
If we take 665 away from 1000, we end up with 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Step 16:
When dividing 3350 by 665, we get 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 77253.42406015
Subtract 3325 from 3350 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The final outcome is 77253.42406015, with a leftover of 2.5e-08.
