86229198 divided by 436 
Our goal is to divide 86229198 by 436.

Going ahead to step 1:
When dividing 8 by 436, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 436

Let's proceed to step 2:
When dividing 86 by 436, we get 0 with a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 86 after subtracting 0 from 86.
Append the next digit (2) from the dividend to 86 and continue with: 862 / 436

Let's proceed to step 3:
436 goes into 862 1 times with a remainder of 426.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 436 away from 862, we end up with 426.
Bring next digit (2) of the dividend behind the 426 and repeat the process: 4262 / 436

Moving on to step 4:
4262 divided by 436 is 9 with a remainder of 338.
Write down 9 as next digit of the result. 
Result so far: 19.0
Subtracting 3924 from 4262 leaves us with 338.
Include the next digit (9) from the dividend after 338, then repeat: 3389 / 436

Step 5:
436 goes into 3389 7 times with a remainder of 337.
Record the quotient 7 as the next digit in the result. 
Result so far: 197.0
Subtracting 3052 from 3389 leaves us with 337.
Grab the next digit (1) from the dividend, add it to 337, then carry on: 3371 / 436

Moving on to step 6:
If we divide 3371 by 436, we get 7 and a remainder of 319.
Record the quotient 7 as the next digit in the result. 
Result so far: 1977.0
Deduct 3052 from 3371 and we're left with 319.
Take the next digit (9) from the dividend and append it to 319, then repeat: 3199 / 436

Step 7:
436 can be fit into 3199 7 times, resulting in a remainder of 147.
Record the quotient 7 as the next digit in the result. 
Result so far: 19777.0
Subtract 3052 from 3199 to get 147.
Grab the next digit (8) from the dividend, add it to 147, then carry on: 1478 / 436

Going ahead to step 8:
436 can be fit into 1478 3 times, resulting in a remainder of 170.
The next digit of our result is 3. 
Result so far: 197773.0
If we subtract 1308 from 1478, we get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

On to step 9:
1700 divided by 436 is 3 with a remainder of 392.
Put 3 as the next digit of the answer. 
Result so far: 197773.3
If we subtract 1308 from 1700, we get 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Let's proceed to step 10:
When dividing 3920 by 436, we get 8 with a remainder of 432.
Put 8 as the next digit of the answer. 
Result so far: 197773.38
Deduct 3488 from 3920 and we're left with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Advancing to step 11:
If we divide 4320 by 436, we get 9 and a remainder of 396.
Put 9 as the next digit of the answer. 
Result so far: 197773.389
Subtract 3924 from 4320 to get 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Going ahead to step 12:
3960 divided by 436 is 9 with a remainder of 36.
Use 9 as the next digit of our solution. 
Result so far: 197773.3899
If we subtract 3924 from 3960, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

After the division, we end up with 197773.3899 and a remainder of 0.00036.
