86135223 divided by 436 
Our goal is to divide 86135223 by 436.

On to step 1:
436 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 436

Advancing to step 2:
86 divided by 436 is 0 with a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 86 to get 86.
Append the next digit (1) from the dividend to 86 and continue with: 861 / 436

Moving on to step 3:
436 goes into 861 1 times with a remainder of 425.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 425 after subtracting 436 from 861.
Take the next digit (3) from the dividend and append it to 425, then repeat: 4253 / 436

Advancing to step 4:
If we divide 4253 by 436, we get 9 and a remainder of 329.
Write down 9 as next digit of the result. 
Result so far: 19.0
Subtracting 3924 from 4253 leaves us with 329.
Include the next digit (5) from the dividend after 329, then repeat: 3295 / 436

Advancing to step 5:
When dividing 3295 by 436, we get 7 with a remainder of 243.
The next digit of our result is 7. 
Result so far: 197.0
Deduct 3052 from 3295 and we're left with 243.
Grab the next digit (2) from the dividend, add it to 243, then carry on: 2432 / 436

Moving on to step 6:
When dividing 2432 by 436, we get 5 with a remainder of 252.
The number 5 becomes the next digit in our result. 
Result so far: 1975.0
Subtract 2180 from 2432 to get 252.
Take the next digit (2) from the dividend and append it to 252, then repeat: 2522 / 436

On to step 7:
436 can be fit into 2522 5 times, resulting in a remainder of 342.
Put 5 as the next digit of the answer. 
Result so far: 19755.0
Deduct 2180 from 2522 and we're left with 342.
Append the next digit (3) from the dividend to 342 and continue with: 3423 / 436

Going ahead to step 8:
3423 divided by 436 is 7 with a remainder of 371.
Record the quotient 7 as the next digit in the result. 
Result so far: 197557.0
The remainder is 371 after subtracting 3052 from 3423.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3710, and continue the process.

Let's proceed to step 9:
When dividing 3710 by 436, we get 8 with a remainder of 222.
The next digit of our result is 8. 
Result so far: 197557.8
If we subtract 3488 from 3710, 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.

Advancing to step 10:
436 goes into 2220 5 times with a remainder of 40.
Use 5 as the next digit of our solution. 
Result so far: 197557.85
If we take 2180 away from 2220, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 11:
400 divided by 436 is 0 with a remainder of 400.
The next digit of our result is 0. 
Result so far: 197557.85
If we subtract 0 from 400, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Step 12:
436 can be fit into 4000 9 times, resulting in a remainder of 76.
Use 9 as the next digit of our solution. 
Result so far: 197557.8509
Subtracting 3924 from 4000 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 13:
If we divide 760 by 436, we get 1 and a remainder of 324.
The number 1 becomes the next digit in our result. 
Result so far: 197557.85091
Subtracting 436 from 760 leaves us with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Advancing to step 14:
When dividing 3240 by 436, we get 7 with a remainder of 188.
The number 7 becomes the next digit in our result. 
Result so far: 197557.850917
Deduct 3052 from 3240 and we're left with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Going ahead to step 15:
436 can be fit into 1880 4 times, resulting in a remainder of 136.
The next digit of our result is 4. 
Result so far: 197557.8509174
If we subtract 1744 from 1880, we get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Moving on to step 16:
The number 436 fits into 1360 3 times, leaving a remainder of 52.
The next digit of our result is 3. 
Result so far: 197557.85091743
Subtract 1308 from 1360 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The final result is 197557.85091743 with a remainder of 5.2e-08.
