We look at the division of 36831851 by 409 
We want to divide 36831851 by 409.

Advancing to step 1:
The number 409 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 409

Advancing to step 2:
36 divided by 409 is 0 with a remainder of 36.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 36, we end up with 36.
Include the next digit (8) from the dividend after 36, then repeat: 368 / 409

Moving on to step 3:
If we divide 368 by 409, we get 0 and a remainder of 368.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 368, we get 368.
Append the next digit (3) from the dividend to 368 and continue with: 3683 / 409

On to step 4:
The number 409 fits into 3683 9 times, leaving a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtracting 3681 from 3683 leaves us with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 409

Moving on to step 5:
409 can be fit into 21 0 times, resulting in a remainder of 21.
The next digit of our result is 0. 
Result so far: 90.0
Subtract 0 from 21 to get 21.
Take the next digit (8) from the dividend and append it to 21, then repeat: 218 / 409

Moving on to step 6:
409 can be fit into 218 0 times, resulting in a remainder of 218.
The next digit of our result is 0. 
Result so far: 900.0
If we take 0 away from 218, we end up with 218.
Take the next digit (5) from the dividend and append it to 218, then repeat: 2185 / 409

Moving on to step 7:
2185 divided by 409 is 5 with a remainder of 140.
The number 5 becomes the next digit in our result. 
Result so far: 9005.0
Subtracting 2045 from 2185 leaves us with 140.
Include the next digit (1) from the dividend after 140, then repeat: 1401 / 409

On to step 8:
The number 409 fits into 1401 3 times, leaving a remainder of 174.
Put 3 as the next digit of the answer. 
Result so far: 90053.0
If we subtract 1227 from 1401, we get 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Let's proceed to step 9:
If we divide 1740 by 409, we get 4 and a remainder of 104.
Use 4 as the next digit of our solution. 
Result so far: 90053.4
Deduct 1636 from 1740 and we're left with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Going ahead to step 10:
If we divide 1040 by 409, we get 2 and a remainder of 222.
Use 2 as the next digit of our solution. 
Result so far: 90053.42
If we subtract 818 from 1040, we get 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Moving on to step 11:
2220 divided by 409 is 5 with a remainder of 175.
Put 5 as the next digit of the answer. 
Result so far: 90053.425
If we subtract 2045 from 2220, we get 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Step 12:
The number 409 fits into 1750 4 times, leaving a remainder of 114.
Write down 4 as next digit of the result. 
Result so far: 90053.4254
If we take 1636 away from 1750, we end up with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Going ahead to step 13:
1140 divided by 409 is 2 with a remainder of 322.
Use 2 as the next digit of our solution. 
Result so far: 90053.42542
Subtracting 818 from 1140 leaves us with 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Advancing to step 14:
The number 409 fits into 3220 7 times, leaving a remainder of 357.
Use 7 as the next digit of our solution. 
Result so far: 90053.425427
Deduct 2863 from 3220 and we're left with 357.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3570, and continue the process.

Going ahead to step 15:
409 goes into 3570 8 times with a remainder of 298.
Record the quotient 8 as the next digit in the result. 
Result so far: 90053.4254278
The remainder is 298 after subtracting 3272 from 3570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Step 16:
The number 409 fits into 2980 7 times, leaving a remainder of 117.
Record the quotient 7 as the next digit in the result. 
Result so far: 90053.42542787
Deduct 2863 from 2980 and we're left with 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

After the division, we end up with 90053.42542787 and a remainder of 1.17e-07.
