We're dividing 41209223 by 402 
We want to divide 41209223 by 402.

On to step 1:
4 divided by 402 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (1) from the dividend to 4 and continue with: 41 / 402

On to step 2:
402 can be fit into 41 0 times, resulting in a remainder of 41.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 41 and we're left with 41.
Fetch the next digit (2) from the dividend, attach it to 41 and continue: 412 / 402

On to step 3:
The number 402 fits into 412 1 times, leaving a remainder of 10.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 402 from 412 leaves us with 10.
Grab the next digit (0) from the dividend, add it to 10, then carry on: 100 / 402

Advancing to step 4:
When dividing 100 by 402, we get 0 with a remainder of 100.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we subtract 0 from 100, we get 100.
Append the next digit (9) from the dividend to 100 and continue with: 1009 / 402

Moving on to step 5:
402 goes into 1009 2 times with a remainder of 205.
The number 2 becomes the next digit in our result. 
Result so far: 102.0
The remainder is 205 after subtracting 804 from 1009.
Fetch the next digit (2) from the dividend, attach it to 205 and continue: 2052 / 402

On to step 6:
2052 divided by 402 is 5 with a remainder of 42.
Use 5 as the next digit of our solution. 
Result so far: 1025.0
If we take 2010 away from 2052, we end up with 42.
Fetch the next digit (2) from the dividend, attach it to 42 and continue: 422 / 402

Advancing to step 7:
When dividing 422 by 402, we get 1 with a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 10251.0
Subtract 402 from 422 to get 20.
Take the next digit (3) from the dividend and append it to 20, then repeat: 203 / 402

Step 8:
402 goes into 203 0 times with a remainder of 203.
Use 0 as the next digit of our solution. 
Result so far: 102510.0
Subtracting 0 from 203 leaves us with 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Going ahead to step 9:
2030 divided by 402 is 5 with a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 102510.5
Subtract 2010 from 2030 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 10:
402 goes into 200 0 times with a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 102510.5
If we take 0 away from 200, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 11:
402 can be fit into 2000 4 times, resulting in a remainder of 392.
Write down 4 as next digit of the result. 
Result so far: 102510.504
The remainder is 392 after subtracting 1608 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Step 12:
402 can be fit into 3920 9 times, resulting in a remainder of 302.
The number 9 becomes the next digit in our result. 
Result so far: 102510.5049
Deduct 3618 from 3920 and we're left with 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Let's proceed to step 13:
3020 divided by 402 is 7 with a remainder of 206.
Record the quotient 7 as the next digit in the result. 
Result so far: 102510.50497
Deduct 2814 from 3020 and we're left with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Moving on to step 14:
402 can be fit into 2060 5 times, resulting in a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 102510.504975
Subtracting 2010 from 2060 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 15:
If we divide 500 by 402, we get 1 and a remainder of 98.
Record the quotient 1 as the next digit in the result. 
Result so far: 102510.5049751
Subtracting 402 from 500 leaves us with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Going ahead to step 16:
When dividing 980 by 402, we get 2 with a remainder of 176.
The next digit of our result is 2. 
Result so far: 102510.50497512
If we take 804 away from 980, we end up with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

After the division, we end up with 102510.50497512 and a remainder of 1.76e-07.
