We look at the division of 40429164 by 801 
Let's see how many times 801 fits into 40429164.

Moving on to step 1:
If we divide 4 by 801, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 801

On to step 2:
If we divide 40 by 801, we get 0 and a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Grab the next digit (4) from the dividend, add it to 40, then carry on: 404 / 801

Let's proceed to step 3:
When dividing 404 by 801, we get 0 with a remainder of 404.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 404 leaves us with 404.
Bring next digit (2) of the dividend behind the 404 and repeat the process: 4042 / 801

On to step 4:
4042 divided by 801 is 5 with a remainder of 37.
The next digit of our result is 5. 
Result so far: 5.0
If we take 4005 away from 4042, we end up with 37.
Bring next digit (9) of the dividend behind the 37 and repeat the process: 379 / 801

On to step 5:
801 goes into 379 0 times with a remainder of 379.
Put 0 as the next digit of the answer. 
Result so far: 50.0
If we take 0 away from 379, we end up with 379.
Bring next digit (1) of the dividend behind the 379 and repeat the process: 3791 / 801

Going ahead to step 6:
The number 801 fits into 3791 4 times, leaving a remainder of 587.
The number 4 becomes the next digit in our result. 
Result so far: 504.0
Subtract 3204 from 3791 to get 587.
Fetch the next digit (6) from the dividend, attach it to 587 and continue: 5876 / 801

Step 7:
801 goes into 5876 7 times with a remainder of 269.
Put 7 as the next digit of the answer. 
Result so far: 5047.0
Subtract 5607 from 5876 to get 269.
Take the next digit (4) from the dividend and append it to 269, then repeat: 2694 / 801

Let's proceed to step 8:
When dividing 2694 by 801, we get 3 with a remainder of 291.
The number 3 becomes the next digit in our result. 
Result so far: 50473.0
Subtracting 2403 from 2694 leaves us with 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

Moving on to step 9:
If we divide 2910 by 801, we get 3 and a remainder of 507.
Put 3 as the next digit of the answer. 
Result so far: 50473.3
Deduct 2403 from 2910 and we're left with 507.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5070, and continue the process.

On to step 10:
5070 divided by 801 is 6 with a remainder of 264.
Use 6 as the next digit of our solution. 
Result so far: 50473.36
Subtracting 4806 from 5070 leaves us with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Going ahead to step 11:
When dividing 2640 by 801, we get 3 with a remainder of 237.
Record the quotient 3 as the next digit in the result. 
Result so far: 50473.363
Subtract 2403 from 2640 to get 237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

Let's proceed to step 12:
If we divide 2370 by 801, we get 2 and a remainder of 768.
The next digit of our result is 2. 
Result so far: 50473.3632
If we subtract 1602 from 2370, we get 768.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7680, and continue the process.

On to step 13:
When dividing 7680 by 801, we get 9 with a remainder of 471.
Write down 9 as next digit of the result. 
Result so far: 50473.36329
Deduct 7209 from 7680 and we're left with 471.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4710, and continue the process.

Advancing to step 14:
The number 801 fits into 4710 5 times, leaving a remainder of 705.
The number 5 becomes the next digit in our result. 
Result so far: 50473.363295
Subtract 4005 from 4710 to get 705.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7050, and continue the process.

Advancing to step 15:
801 can be fit into 7050 8 times, resulting in a remainder of 642.
The number 8 becomes the next digit in our result. 
Result so far: 50473.3632958
If we subtract 6408 from 7050, we get 642.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6420, and continue the process.

Let's proceed to step 16:
801 can be fit into 6420 8 times, resulting in a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 50473.36329588
The remainder is 12 after subtracting 6408 from 6420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The quotient of the division is 50473.36329588, and the remainder is 1.2e-08.
