We look at the division of 31555681 by 802 
Our goal is to divide 31555681 by 802.

Advancing to step 1:
802 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 802

Step 2:
When dividing 31 by 802, we get 0 with a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Fetch the next digit (5) from the dividend, attach it to 31 and continue: 315 / 802

Advancing to step 3:
If we divide 315 by 802, we get 0 and a remainder of 315.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 315, we get 315.
Include the next digit (5) from the dividend after 315, then repeat: 3155 / 802

Let's proceed to step 4:
When dividing 3155 by 802, we get 3 with a remainder of 749.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 2406 from 3155 and we're left with 749.
Include the next digit (5) from the dividend after 749, then repeat: 7495 / 802

Moving on to step 5:
802 can be fit into 7495 9 times, resulting in a remainder of 277.
Record the quotient 9 as the next digit in the result. 
Result so far: 39.0
Deduct 7218 from 7495 and we're left with 277.
Include the next digit (6) from the dividend after 277, then repeat: 2776 / 802

On to step 6:
802 goes into 2776 3 times with a remainder of 370.
Record the quotient 3 as the next digit in the result. 
Result so far: 393.0
If we subtract 2406 from 2776, we get 370.
Grab the next digit (8) from the dividend, add it to 370, then carry on: 3708 / 802

On to step 7:
When dividing 3708 by 802, we get 4 with a remainder of 500.
Record the quotient 4 as the next digit in the result. 
Result so far: 3934.0
Subtract 3208 from 3708 to get 500.
Bring next digit (1) of the dividend behind the 500 and repeat the process: 5001 / 802

Advancing to step 8:
5001 divided by 802 is 6 with a remainder of 189.
Record the quotient 6 as the next digit in the result. 
Result so far: 39346.0
Subtract 4812 from 5001 to get 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Step 9:
If we divide 1890 by 802, we get 2 and a remainder of 286.
Use 2 as the next digit of our solution. 
Result so far: 39346.2
If we subtract 1604 from 1890, we get 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Going ahead to step 10:
The number 802 fits into 2860 3 times, leaving a remainder of 454.
The number 3 becomes the next digit in our result. 
Result so far: 39346.23
Deduct 2406 from 2860 and we're left with 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

Step 11:
802 can be fit into 4540 5 times, resulting in a remainder of 530.
Use 5 as the next digit of our solution. 
Result so far: 39346.235
If we take 4010 away from 4540, we end up with 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Advancing to step 12:
802 goes into 5300 6 times with a remainder of 488.
Record the quotient 6 as the next digit in the result. 
Result so far: 39346.2356
Subtract 4812 from 5300 to get 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

On to step 13:
If we divide 4880 by 802, we get 6 and a remainder of 68.
Put 6 as the next digit of the answer. 
Result so far: 39346.23566
Deduct 4812 from 4880 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

The final result is 39346.23566 with a remainder of 6.8e-05.
