We're dividing 86120397 by 436 
We want to figure out the number of times 86120397 can be divided by 436.

Let's proceed to step 1:
436 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 436

Going ahead to step 2:
If we divide 86 by 436, we get 0 and a remainder of 86.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Grab the next digit (1) from the dividend, add it to 86, then carry on: 861 / 436

Moving on to step 3:
436 goes into 861 1 times with a remainder of 425.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 436 from 861 leaves us with 425.
Include the next digit (2) from the dividend after 425, then repeat: 4252 / 436

Advancing to step 4:
The number 436 fits into 4252 9 times, leaving a remainder of 328.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
The remainder is 328 after subtracting 3924 from 4252.
Include the next digit (0) from the dividend after 328, then repeat: 3280 / 436

Moving on to step 5:
When dividing 3280 by 436, we get 7 with a remainder of 228.
The next digit of our result is 7. 
Result so far: 197.0
Subtract 3052 from 3280 to get 228.
Append the next digit (3) from the dividend to 228 and continue with: 2283 / 436

Going ahead to step 6:
436 can be fit into 2283 5 times, resulting in a remainder of 103.
Put 5 as the next digit of the answer. 
Result so far: 1975.0
The remainder is 103 after subtracting 2180 from 2283.
Include the next digit (9) from the dividend after 103, then repeat: 1039 / 436

Advancing to step 7:
436 can be fit into 1039 2 times, resulting in a remainder of 167.
The next digit of our result is 2. 
Result so far: 19752.0
If we subtract 872 from 1039, we get 167.
Take the next digit (7) from the dividend and append it to 167, then repeat: 1677 / 436

Step 8:
If we divide 1677 by 436, we get 3 and a remainder of 369.
The next digit of our result is 3. 
Result so far: 197523.0
Subtracting 1308 from 1677 leaves us with 369.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3690, and continue the process.

On to step 9:
If we divide 3690 by 436, we get 8 and a remainder of 202.
Record the quotient 8 as the next digit in the result. 
Result so far: 197523.8
The remainder is 202 after subtracting 3488 from 3690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

On to step 10:
When dividing 2020 by 436, we get 4 with a remainder of 276.
Write down 4 as next digit of the result. 
Result so far: 197523.84
Subtract 1744 from 2020 to get 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

On to step 11:
When dividing 2760 by 436, we get 6 with a remainder of 144.
Put 6 as the next digit of the answer. 
Result so far: 197523.846
Deduct 2616 from 2760 and we're left with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Advancing to step 12:
436 goes into 1440 3 times with a remainder of 132.
The next digit of our result is 3. 
Result so far: 197523.8463
Deduct 1308 from 1440 and we're left with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Moving on to step 13:
The number 436 fits into 1320 3 times, leaving a remainder of 12.
Use 3 as the next digit of our solution. 
Result so far: 197523.84633
The remainder is 12 after subtracting 1308 from 1320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The quotient of the division is 197523.84633, and the remainder is 1.2e-05.
