Let's divide 37143223 by 409
Our goal is to divide 37143223 by 409.

Going ahead to step 1:
3 divided by 409 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 409

Going ahead to step 2:
When dividing 37 by 409, we get 0 with a remainder of 37.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 37 and we're left with 37.
Bring next digit (1) of the dividend behind the 37 and repeat the process: 371 / 409

Advancing to step 3:
409 goes into 371 0 times with a remainder of 371.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 371, we end up with 371.
Bring next digit (4) of the dividend behind the 371 and repeat the process: 3714 / 409

Advancing to step 4:
When dividing 3714 by 409, we get 9 with a remainder of 33.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Deduct 3681 from 3714 and we're left with 33.
Grab the next digit (3) from the dividend, add it to 33, then carry on: 333 / 409

Going ahead to step 5:
333 divided by 409 is 0 with a remainder of 333.
Put 0 as the next digit of the answer. 
Result so far: 90.0
Subtracting 0 from 333 leaves us with 333.
Append the next digit (2) from the dividend to 333 and continue with: 3332 / 409

Moving on to step 6:
The number 409 fits into 3332 8 times, leaving a remainder of 60.
The number 8 becomes the next digit in our result. 
Result so far: 908.0
If we subtract 3272 from 3332, we get 60.
Take the next digit (2) from the dividend and append it to 60, then repeat: 602 / 409

Going ahead to step 7:
602 divided by 409 is 1 with a remainder of 193.
Record the quotient 1 as the next digit in the result. 
Result so far: 9081.0
The remainder is 193 after subtracting 409 from 602.
Append the next digit (3) from the dividend to 193 and continue with: 1933 / 409

Step 8:
When dividing 1933 by 409, we get 4 with a remainder of 297.
Record the quotient 4 as the next digit in the result. 
Result so far: 90814.0
If we subtract 1636 from 1933, we get 297.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2970, and continue the process.

Advancing to step 9:
409 can be fit into 2970 7 times, resulting in a remainder of 107.
Use 7 as the next digit of our solution. 
Result so far: 90814.7
If we take 2863 away from 2970, we end up with 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Going ahead to step 10:
If we divide 1070 by 409, we get 2 and a remainder of 252.
The next digit of our result is 2. 
Result so far: 90814.72
Deduct 818 from 1070 and we're left with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Advancing to step 11:
If we divide 2520 by 409, we get 6 and a remainder of 66.
Use 6 as the next digit of our solution. 
Result so far: 90814.726
Deduct 2454 from 2520 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 12:
660 divided by 409 is 1 with a remainder of 251.
Put 1 as the next digit of the answer. 
Result so far: 90814.7261
The remainder is 251 after subtracting 409 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

Advancing to step 13:
If we divide 2510 by 409, we get 6 and a remainder of 56.
The next digit of our result is 6. 
Result so far: 90814.72616
If we subtract 2454 from 2510, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 14:
409 goes into 560 1 times with a remainder of 151.
Put 1 as the next digit of the answer. 
Result so far: 90814.726161
If we take 409 away from 560, we end up with 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

On to step 15:
409 goes into 1510 3 times with a remainder of 283.
Write down 3 as next digit of the result. 
Result so far: 90814.7261613
If we subtract 1227 from 1510, we get 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

On to step 16:
The number 409 fits into 2830 6 times, leaving a remainder of 376.
Write down 6 as next digit of the result. 
Result so far: 90814.72616136
Subtract 2454 from 2830 to get 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

The final result is 90814.72616136 with a remainder of 3.76e-07.
