We divide 40571815 by 51
Our goal is to divide 40571815 by 51.

Step 1:
If we divide 4 by 51, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 51

Moving on to step 2:
If we divide 40 by 51, we get 0 and a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Include the next digit (5) from the dividend after 40, then repeat: 405 / 51

Going ahead to step 3:
51 can be fit into 405 7 times, resulting in a remainder of 48.
Put 7 as the next digit of the answer. 
Result so far: 7.0
The remainder is 48 after subtracting 357 from 405.
Grab the next digit (7) from the dividend, add it to 48, then carry on: 487 / 51

Step 4:
The number 51 fits into 487 9 times, leaving a remainder of 28.
Put 9 as the next digit of the answer. 
Result so far: 79.0
Deduct 459 from 487 and we're left with 28.
Append the next digit (1) from the dividend to 28 and continue with: 281 / 51

Moving on to step 5:
51 goes into 281 5 times with a remainder of 26.
Put 5 as the next digit of the answer. 
Result so far: 795.0
Subtracting 255 from 281 leaves us with 26.
Include the next digit (8) from the dividend after 26, then repeat: 268 / 51

Let's proceed to step 6:
If we divide 268 by 51, we get 5 and a remainder of 13.
The number 5 becomes the next digit in our result. 
Result so far: 7955.0
Deduct 255 from 268 and we're left with 13.
Grab the next digit (1) from the dividend, add it to 13, then carry on: 131 / 51

Moving on to step 7:
51 goes into 131 2 times with a remainder of 29.
The number 2 becomes the next digit in our result. 
Result so far: 79552.0
If we take 102 away from 131, we end up with 29.
Fetch the next digit (5) from the dividend, attach it to 29 and continue: 295 / 51

Moving on to step 8:
If we divide 295 by 51, we get 5 and a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 795525.0
If we subtract 255 from 295, 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.

Going ahead to step 9:
When dividing 400 by 51, we get 7 with a remainder of 43.
Record the quotient 7 as the next digit in the result. 
Result so far: 795525.7
Subtract 357 from 400 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 10:
430 divided by 51 is 8 with a remainder of 22.
Write down 8 as next digit of the result. 
Result so far: 795525.78
The remainder is 22 after subtracting 408 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 11:
When dividing 220 by 51, we get 4 with a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 795525.784
If we take 204 away from 220, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 12:
51 goes into 160 3 times with a remainder of 7.
The next digit of our result is 3. 
Result so far: 795525.7843
Subtracting 153 from 160 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 13:
When dividing 70 by 51, we get 1 with a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 795525.78431
Deduct 51 from 70 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 14:
If we divide 190 by 51, we get 3 and a remainder of 37.
Put 3 as the next digit of the answer. 
Result so far: 795525.784313
If we take 153 away from 190, 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.

Step 15:
370 divided by 51 is 7 with a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 795525.7843137
The remainder is 13 after subtracting 357 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 16:
51 can be fit into 130 2 times, resulting in a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 795525.78431372
If we subtract 102 from 130, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Our division results in 795525.78431372 with a remaining 2.8e-08.
