Let's divide 86259851 by 419
We're looking to find how many times 419 goes into 86259851.

Going ahead to step 1:
The number 419 fits into 8 0 times, leaving 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.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 419

Advancing to step 2:
86 divided by 419 is 0 with a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 86 to get 86.
Include the next digit (2) from the dividend after 86, then repeat: 862 / 419

Advancing to step 3:
862 divided by 419 is 2 with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 24 after subtracting 838 from 862.
Append the next digit (5) from the dividend to 24 and continue with: 245 / 419

Going ahead to step 4:
419 can be fit into 245 0 times, resulting in a remainder of 245.
Put 0 as the next digit of the answer. 
Result so far: 20.0
If we take 0 away from 245, we end up with 245.
Append the next digit (9) from the dividend to 245 and continue with: 2459 / 419

Moving on to step 5:
When dividing 2459 by 419, we get 5 with a remainder of 364.
The number 5 becomes the next digit in our result. 
Result so far: 205.0
Subtracting 2095 from 2459 leaves us with 364.
Take the next digit (8) from the dividend and append it to 364, then repeat: 3648 / 419

On to step 6:
3648 divided by 419 is 8 with a remainder of 296.
Put 8 as the next digit of the answer. 
Result so far: 2058.0
If we take 3352 away from 3648, we end up with 296.
Include the next digit (5) from the dividend after 296, then repeat: 2965 / 419

Step 7:
419 can be fit into 2965 7 times, resulting in a remainder of 32.
The number 7 becomes the next digit in our result. 
Result so far: 20587.0
Subtracting 2933 from 2965 leaves us with 32.
Bring next digit (1) of the dividend behind the 32 and repeat the process: 321 / 419

Step 8:
If we divide 321 by 419, we get 0 and a remainder of 321.
Write down 0 as next digit of the result. 
Result so far: 205870.0
Subtracting 0 from 321 leaves us with 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

On to step 9:
When dividing 3210 by 419, we get 7 with a remainder of 277.
Record the quotient 7 as the next digit in the result. 
Result so far: 205870.7
Subtracting 2933 from 3210 leaves us with 277.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2770, and continue the process.

Step 10:
419 can be fit into 2770 6 times, resulting in a remainder of 256.
Use 6 as the next digit of our solution. 
Result so far: 205870.76
Subtract 2514 from 2770 to get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Moving on to step 11:
When dividing 2560 by 419, we get 6 with a remainder of 46.
The number 6 becomes the next digit in our result. 
Result so far: 205870.766
Deduct 2514 from 2560 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

In conclusion, the division gives 205870.766 with a balance of 0.0046.
