We look at the division of 10853661 by 402 
We're looking to find how many times 402 goes into 10853661.

Advancing to step 1:
When dividing 1 by 402, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 402

Going ahead to step 2:
402 goes into 10 0 times with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 10 and we're left with 10.
Include the next digit (8) from the dividend after 10, then repeat: 108 / 402

Advancing to step 3:
402 can be fit into 108 0 times, resulting in a remainder of 108.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 108, we get 108.
Bring next digit (5) of the dividend behind the 108 and repeat the process: 1085 / 402

On to step 4:
When dividing 1085 by 402, we get 2 with a remainder of 281.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 804 from 1085 and we're left with 281.
Append the next digit (3) from the dividend to 281 and continue with: 2813 / 402

Going ahead to step 5:
2813 divided by 402 is 6 with a remainder of 401.
The next digit of our result is 6. 
Result so far: 26.0
The remainder is 401 after subtracting 2412 from 2813.
Take the next digit (6) from the dividend and append it to 401, then repeat: 4016 / 402

Let's proceed to step 6:
4016 divided by 402 is 9 with a remainder of 398.
Record the quotient 9 as the next digit in the result. 
Result so far: 269.0
If we take 3618 away from 4016, we end up with 398.
Append the next digit (6) from the dividend to 398 and continue with: 3986 / 402

Step 7:
If we divide 3986 by 402, we get 9 and a remainder of 368.
Put 9 as the next digit of the answer. 
Result so far: 2699.0
Subtract 3618 from 3986 to get 368.
Append the next digit (1) from the dividend to 368 and continue with: 3681 / 402

On to step 8:
The number 402 fits into 3681 9 times, leaving a remainder of 63.
The next digit of our result is 9. 
Result so far: 26999.0
Deduct 3618 from 3681 and we're left with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Advancing to step 9:
When dividing 630 by 402, we get 1 with a remainder of 228.
Record the quotient 1 as the next digit in the result. 
Result so far: 26999.1
Deduct 402 from 630 and we're left with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Let's proceed to step 10:
When dividing 2280 by 402, we get 5 with a remainder of 270.
Use 5 as the next digit of our solution. 
Result so far: 26999.15
If we take 2010 away from 2280, we end up with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Let's proceed to step 11:
If we divide 2700 by 402, we get 6 and a remainder of 288.
The number 6 becomes the next digit in our result. 
Result so far: 26999.156
Deduct 2412 from 2700 and we're left with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Let's proceed to step 12:
402 can be fit into 2880 7 times, resulting in a remainder of 66.
The number 7 becomes the next digit in our result. 
Result so far: 26999.1567
Subtract 2814 from 2880 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 13:
402 can be fit into 660 1 times, resulting in a remainder of 258.
The next digit of our result is 1. 
Result so far: 26999.15671
Subtracting 402 from 660 leaves us with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Going ahead to step 14:
402 can be fit into 2580 6 times, resulting in a remainder of 168.
Record the quotient 6 as the next digit in the result. 
Result so far: 26999.156716
The remainder is 168 after subtracting 2412 from 2580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Step 15:
When dividing 1680 by 402, we get 4 with a remainder of 72.
The next digit of our result is 4. 
Result so far: 26999.1567164
Deduct 1608 from 1680 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 16:
402 can be fit into 720 1 times, resulting in a remainder of 318.
The next digit of our result is 1. 
Result so far: 26999.15671641
Deduct 402 from 720 and we're left with 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

After the division, we end up with 26999.15671641 and a remainder of 3.18e-07.
