Let's divide 420744 by 86
We want to divide 420744 by 86.

Going ahead to step 1:
86 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 86

Let's proceed to step 2:
86 goes into 42 0 times with a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Bring next digit (0) of the dividend behind the 42 and repeat the process: 420 / 86

Moving on to step 3:
If we divide 420 by 86, we get 4 and a remainder of 76.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 344 from 420, we get 76.
Include the next digit (7) from the dividend after 76, then repeat: 767 / 86

Let's proceed to step 4:
86 can be fit into 767 8 times, resulting in a remainder of 79.
Use 8 as the next digit of our solution. 
Result so far: 48.0
Subtracting 688 from 767 leaves us with 79.
Grab the next digit (4) from the dividend, add it to 79, then carry on: 794 / 86

Let's proceed to step 5:
794 divided by 86 is 9 with a remainder of 20.
The next digit of our result is 9. 
Result so far: 489.0
If we take 774 away from 794, we end up with 20.
Bring next digit (4) of the dividend behind the 20 and repeat the process: 204 / 86

Moving on to step 6:
204 divided by 86 is 2 with a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 4892.0
Subtracting 172 from 204 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 7:
If we divide 320 by 86, we get 3 and a remainder of 62.
The number 3 becomes the next digit in our result. 
Result so far: 4892.3
Deduct 258 from 320 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 8:
When dividing 620 by 86, we get 7 with a remainder of 18.
Record the quotient 7 as the next digit in the result. 
Result so far: 4892.37
Subtracting 602 from 620 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 9:
86 goes into 180 2 times with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 4892.372
Subtracting 172 from 180 leaves us 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.

On to step 10:
When dividing 80 by 86, we get 0 with a remainder of 80.
The next digit of our result is 0. 
Result so far: 4892.372
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 11:
800 divided by 86 is 9 with a remainder of 26.
Use 9 as the next digit of our solution. 
Result so far: 4892.37209
If we take 774 away from 800, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 12:
86 can be fit into 260 3 times, resulting in a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 4892.372093
If we take 258 away from 260, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 13:
86 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 4892.372093
Deduct 0 from 20 and we're left 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.

Advancing to step 14:
86 goes into 200 2 times with a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 4892.37209302
Subtract 172 from 200 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Our division results in 4892.37209302 with a remaining 2.8e-08.
