We're dividing 84434871 by 402 
We want to figure out the number of times 84434871 can be divided by 402.

Step 1:
402 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 402

Let's proceed to step 2:
When dividing 84 by 402, we get 0 with a remainder of 84.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 84 to get 84.
Bring next digit (4) of the dividend behind the 84 and repeat the process: 844 / 402

Advancing to step 3:
When dividing 844 by 402, we get 2 with a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 804 from 844 to get 40.
Bring next digit (3) of the dividend behind the 40 and repeat the process: 403 / 402

Going ahead to step 4:
403 divided by 402 is 1 with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 21.0
Subtract 402 from 403 to get 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 402

Let's proceed to step 5:
14 divided by 402 is 0 with a remainder of 14.
The next digit of our result is 0. 
Result so far: 210.0
The remainder is 14 after subtracting 0 from 14.
Grab the next digit (8) from the dividend, add it to 14, then carry on: 148 / 402

On to step 6:
402 goes into 148 0 times with a remainder of 148.
Put 0 as the next digit of the answer. 
Result so far: 2100.0
Subtracting 0 from 148 leaves us with 148.
Append the next digit (7) from the dividend to 148 and continue with: 1487 / 402

On to step 7:
1487 divided by 402 is 3 with a remainder of 281.
Record the quotient 3 as the next digit in the result. 
Result so far: 21003.0
Deduct 1206 from 1487 and we're left with 281.
Bring next digit (1) of the dividend behind the 281 and repeat the process: 2811 / 402

Moving on to step 8:
The number 402 fits into 2811 6 times, leaving a remainder of 399.
The next digit of our result is 6. 
Result so far: 210036.0
Subtracting 2412 from 2811 leaves us with 399.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3990, and continue the process.

Moving on to step 9:
When dividing 3990 by 402, we get 9 with a remainder of 372.
Record the quotient 9 as the next digit in the result. 
Result so far: 210036.9
Deduct 3618 from 3990 and we're left with 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

On to step 10:
3720 divided by 402 is 9 with a remainder of 102.
Record the quotient 9 as the next digit in the result. 
Result so far: 210036.99
Deduct 3618 from 3720 and we're left with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

In conclusion, the division gives 210036.99 with a balance of 0.102.
