1842673 ÷ 86 
Let's see how many times 86 fits into 1842673.

On to step 1:
86 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 86

On to step 2:
18 divided by 86 is 0 with a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 18, we end up with 18.
Append the next digit (4) from the dividend to 18 and continue with: 184 / 86

Let's proceed to step 3:
The number 86 fits into 184 2 times, leaving a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 172 from 184 and we're left with 12.
Take the next digit (2) from the dividend and append it to 12, then repeat: 122 / 86

Step 4:
If we divide 122 by 86, we get 1 and a remainder of 36.
Write down 1 as next digit of the result. 
Result so far: 21.0
If we subtract 86 from 122, we get 36.
Bring next digit (6) of the dividend behind the 36 and repeat the process: 366 / 86

Going ahead to step 5:
The number 86 fits into 366 4 times, leaving a remainder of 22.
The next digit of our result is 4. 
Result so far: 214.0
The remainder is 22 after subtracting 344 from 366.
Bring next digit (7) of the dividend behind the 22 and repeat the process: 227 / 86

Step 6:
227 divided by 86 is 2 with a remainder of 55.
Put 2 as the next digit of the answer. 
Result so far: 2142.0
If we subtract 172 from 227, we get 55.
Grab the next digit (3) from the dividend, add it to 55, then carry on: 553 / 86

Advancing to step 7:
86 goes into 553 6 times with a remainder of 37.
Record the quotient 6 as the next digit in the result. 
Result so far: 21426.0
Deduct 516 from 553 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 8:
The number 86 fits into 370 4 times, leaving a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 21426.4
The remainder is 26 after subtracting 344 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 9:
260 divided by 86 is 3 with a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 21426.43
The remainder is 2 after subtracting 258 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 10:
When dividing 20 by 86, we get 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 21426.43
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 11:
If we divide 200 by 86, we get 2 and a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 21426.4302
Subtracting 172 from 200 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 12:
86 can be fit into 280 3 times, resulting in a remainder of 22.
Put 3 as the next digit of the answer. 
Result so far: 21426.43023
If we subtract 258 from 280, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 13:
86 can be fit into 220 2 times, resulting in a remainder of 48.
Write down 2 as next digit of the result. 
Result so far: 21426.430232
Subtract 172 from 220 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 14:
If we divide 480 by 86, we get 5 and a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 21426.4302325
Subtract 430 from 480 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 15:
When dividing 500 by 86, we get 5 with a remainder of 70.
The number 5 becomes the next digit in our result. 
Result so far: 21426.43023255
Deduct 430 from 500 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final outcome is 21426.43023255, with a leftover of 7e-08.
