We're dividing 86955120 by 431 
We want to divide 86955120 by 431.

Advancing to step 1:
The number 431 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 431

Moving on to step 2:
The number 431 fits into 86 0 times, leaving a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Fetch the next digit (9) from the dividend, attach it to 86 and continue: 869 / 431

Let's proceed to step 3:
431 can be fit into 869 2 times, resulting in a remainder of 7.
The next digit of our result is 2. 
Result so far: 2.0
If we take 862 away from 869, we end up with 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 431

Moving on to step 4:
When dividing 75 by 431, we get 0 with a remainder of 75.
Put 0 as the next digit of the answer. 
Result so far: 20.0
Subtracting 0 from 75 leaves us with 75.
Include the next digit (5) from the dividend after 75, then repeat: 755 / 431

Moving on to step 5:
755 divided by 431 is 1 with a remainder of 324.
Put 1 as the next digit of the answer. 
Result so far: 201.0
The remainder is 324 after subtracting 431 from 755.
Append the next digit (1) from the dividend to 324 and continue with: 3241 / 431

Going ahead to step 6:
If we divide 3241 by 431, we get 7 and a remainder of 224.
Use 7 as the next digit of our solution. 
Result so far: 2017.0
The remainder is 224 after subtracting 3017 from 3241.
Append the next digit (2) from the dividend to 224 and continue with: 2242 / 431

Going ahead to step 7:
If we divide 2242 by 431, we get 5 and a remainder of 87.
Put 5 as the next digit of the answer. 
Result so far: 20175.0
Deduct 2155 from 2242 and we're left with 87.
Take the next digit (0) from the dividend and append it to 87, then repeat: 870 / 431

Going ahead to step 8:
The number 431 fits into 870 2 times, leaving a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 201752.0
Deduct 862 from 870 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 9:
When dividing 80 by 431, we get 0 with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 201752.0
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 10:
If we divide 800 by 431, we get 1 and a remainder of 369.
Write down 1 as next digit of the result. 
Result so far: 201752.01
If we take 431 away from 800, we end up 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.

Step 11:
When dividing 3690 by 431, we get 8 with a remainder of 242.
Use 8 as the next digit of our solution. 
Result so far: 201752.018
Deduct 3448 from 3690 and we're left with 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Going ahead to step 12:
2420 divided by 431 is 5 with a remainder of 265.
Write down 5 as next digit of the result. 
Result so far: 201752.0185
Subtracting 2155 from 2420 leaves us with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Moving on to step 13:
If we divide 2650 by 431, we get 6 and a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 201752.01856
The remainder is 64 after subtracting 2586 from 2650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 14:
If we divide 640 by 431, we get 1 and a remainder of 209.
Put 1 as the next digit of the answer. 
Result so far: 201752.018561
Deduct 431 from 640 and we're left with 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Moving on to step 15:
431 can be fit into 2090 4 times, resulting in a remainder of 366.
Put 4 as the next digit of the answer. 
Result so far: 201752.0185614
Deduct 1724 from 2090 and we're left with 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Moving on to step 16:
When dividing 3660 by 431, we get 8 with a remainder of 212.
The number 8 becomes the next digit in our result. 
Result so far: 201752.01856148
Subtract 3448 from 3660 to get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

After the division, we end up with 201752.01856148 and a remainder of 2.12e-07.
