We're dividing 86421208 by 206 
We want to divide 86421208 by 206.

Let's proceed to step 1:
If we divide 8 by 206, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 206

Moving on to step 2:
If we divide 86 by 206, we get 0 and a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Fetch the next digit (4) from the dividend, attach it to 86 and continue: 864 / 206

Step 3:
206 goes into 864 4 times with a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 824 from 864 to get 40.
Take the next digit (2) from the dividend and append it to 40, then repeat: 402 / 206

Moving on to step 4:
When dividing 402 by 206, we get 1 with a remainder of 196.
Write down 1 as next digit of the result. 
Result so far: 41.0
Deduct 206 from 402 and we're left with 196.
Take the next digit (1) from the dividend and append it to 196, then repeat: 1961 / 206

Moving on to step 5:
The number 206 fits into 1961 9 times, leaving a remainder of 107.
Use 9 as the next digit of our solution. 
Result so far: 419.0
Subtracting 1854 from 1961 leaves us with 107.
Include the next digit (2) from the dividend after 107, then repeat: 1072 / 206

Advancing to step 6:
1072 divided by 206 is 5 with a remainder of 42.
The next digit of our result is 5. 
Result so far: 4195.0
Deduct 1030 from 1072 and we're left with 42.
Include the next digit (0) from the dividend after 42, then repeat: 420 / 206

On to step 7:
The number 206 fits into 420 2 times, leaving a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 41952.0
If we take 412 away from 420, we end up with 8.
Append the next digit (8) from the dividend to 8 and continue with: 88 / 206

Let's proceed to step 8:
206 can be fit into 88 0 times, resulting in a remainder of 88.
The number 0 becomes the next digit in our result. 
Result so far: 419520.0
The remainder is 88 after subtracting 0 from 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

On to step 9:
If we divide 880 by 206, we get 4 and a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 419520.4
Subtract 824 from 880 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 10:
When dividing 560 by 206, we get 2 with a remainder of 148.
The next digit of our result is 2. 
Result so far: 419520.42
If we subtract 412 from 560, we get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Advancing to step 11:
If we divide 1480 by 206, we get 7 and a remainder of 38.
Put 7 as the next digit of the answer. 
Result so far: 419520.427
If we take 1442 away from 1480, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 12:
The number 206 fits into 380 1 times, leaving a remainder of 174.
Write down 1 as next digit of the result. 
Result so far: 419520.4271
If we take 206 away from 380, we end up with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Going ahead to step 13:
The number 206 fits into 1740 8 times, leaving a remainder of 92.
Put 8 as the next digit of the answer. 
Result so far: 419520.42718
If we subtract 1648 from 1740, we get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Advancing to step 14:
When dividing 920 by 206, we get 4 with a remainder of 96.
The next digit of our result is 4. 
Result so far: 419520.427184
The remainder is 96 after subtracting 824 from 920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Let's proceed to step 15:
206 goes into 960 4 times with a remainder of 136.
Write down 4 as next digit of the result. 
Result so far: 419520.4271844
If we take 824 away from 960, we end up with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

In conclusion, the division gives 419520.4271844 with a balance of 1.36e-06.
