Let's divide 40219571 by 286
Our goal is to divide 40219571 by 286.

On to step 1:
If we divide 4 by 286, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 286

Going ahead to step 2:
The number 286 fits into 40 0 times, leaving a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 40, we end up with 40.
Fetch the next digit (2) from the dividend, attach it to 40 and continue: 402 / 286

Advancing to step 3:
286 goes into 402 1 times with a remainder of 116.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 286 from 402 leaves us with 116.
Fetch the next digit (1) from the dividend, attach it to 116 and continue: 1161 / 286

Advancing to step 4:
286 goes into 1161 4 times with a remainder of 17.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
If we take 1144 away from 1161, we end up with 17.
Grab the next digit (9) from the dividend, add it to 17, then carry on: 179 / 286

Let's proceed to step 5:
If we divide 179 by 286, we get 0 and a remainder of 179.
The next digit of our result is 0. 
Result so far: 140.0
If we subtract 0 from 179, we get 179.
Include the next digit (5) from the dividend after 179, then repeat: 1795 / 286

Step 6:
286 can be fit into 1795 6 times, resulting in a remainder of 79.
Use 6 as the next digit of our solution. 
Result so far: 1406.0
If we take 1716 away from 1795, we end up with 79.
Take the next digit (7) from the dividend and append it to 79, then repeat: 797 / 286

Step 7:
When dividing 797 by 286, we get 2 with a remainder of 225.
Use 2 as the next digit of our solution. 
Result so far: 14062.0
Deduct 572 from 797 and we're left with 225.
Take the next digit (1) from the dividend and append it to 225, then repeat: 2251 / 286

Advancing to step 8:
The number 286 fits into 2251 7 times, leaving a remainder of 249.
Record the quotient 7 as the next digit in the result. 
Result so far: 140627.0
If we subtract 2002 from 2251, we get 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

On to step 9:
If we divide 2490 by 286, we get 8 and a remainder of 202.
Write down 8 as next digit of the result. 
Result so far: 140627.8
If we subtract 2288 from 2490, we get 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Step 10:
286 can be fit into 2020 7 times, resulting in a remainder of 18.
The next digit of our result is 7. 
Result so far: 140627.87
Deduct 2002 from 2020 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 11:
286 can be fit into 180 0 times, resulting in a remainder of 180.
Write down 0 as next digit of the result. 
Result so far: 140627.87
Subtracting 0 from 180 leaves us with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 12:
If we divide 1800 by 286, we get 6 and a remainder of 84.
Put 6 as the next digit of the answer. 
Result so far: 140627.8706
If we take 1716 away from 1800, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Moving on to step 13:
286 can be fit into 840 2 times, resulting in a remainder of 268.
Record the quotient 2 as the next digit in the result. 
Result so far: 140627.87062
Subtract 572 from 840 to get 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Going ahead to step 14:
286 can be fit into 2680 9 times, resulting in a remainder of 106.
The next digit of our result is 9. 
Result so far: 140627.870629
Subtracting 2574 from 2680 leaves us with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Let's proceed to step 15:
1060 divided by 286 is 3 with a remainder of 202.
Put 3 as the next digit of the answer. 
Result so far: 140627.8706293
The remainder is 202 after subtracting 858 from 1060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Advancing to step 16:
The number 286 fits into 2020 7 times, leaving a remainder of 18.
Write down 7 as next digit of the result. 
Result so far: 140627.87062937
Deduct 2002 from 2020 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final result is 140627.87062937 with a remainder of 1.8e-08.
