420128 divided by 86 
We're looking to find how many times 86 goes into 420128.

Let's proceed to step 1:
The number 86 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 86

Step 2:
42 divided by 86 is 0 with a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Grab the next digit (0) from the dividend, add it to 42, then carry on: 420 / 86

Step 3:
420 divided by 86 is 4 with a remainder of 76.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 344 from 420 and we're left with 76.
Fetch the next digit (1) from the dividend, attach it to 76 and continue: 761 / 86

On to step 4:
761 divided by 86 is 8 with a remainder of 73.
Record the quotient 8 as the next digit in the result. 
Result so far: 48.0
Deduct 688 from 761 and we're left with 73.
Include the next digit (2) from the dividend after 73, then repeat: 732 / 86

Advancing to step 5:
If we divide 732 by 86, we get 8 and a remainder of 44.
Put 8 as the next digit of the answer. 
Result so far: 488.0
Subtract 688 from 732 to get 44.
Fetch the next digit (8) from the dividend, attach it to 44 and continue: 448 / 86

Moving on to step 6:
If we divide 448 by 86, we get 5 and a remainder of 18.
Use 5 as the next digit of our solution. 
Result so far: 4885.0
The remainder is 18 after subtracting 430 from 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 7:
When dividing 180 by 86, we get 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 4885.2
If we subtract 172 from 180, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 8:
The number 86 fits into 80 0 times, leaving a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 4885.2
Subtract 0 from 80 to get 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 9:
The number 86 fits into 800 9 times, leaving a remainder of 26.
The number 9 becomes the next digit in our result. 
Result so far: 4885.209
If we subtract 774 from 800, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 10:
86 goes into 260 3 times with a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 4885.2093
Subtracting 258 from 260 leaves us 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.

Step 11:
The number 86 fits into 20 0 times, leaving a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 4885.2093
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.

Let's proceed to step 12:
When dividing 200 by 86, we get 2 with a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 4885.209302
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.

Let's proceed to step 13:
86 can be fit into 280 3 times, resulting in a remainder of 22.
The next digit of our result is 3. 
Result so far: 4885.2093023
If we take 258 away from 280, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 14:
220 divided by 86 is 2 with a remainder of 48.
Use 2 as the next digit of our solution. 
Result so far: 4885.20930232
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.

The quotient of the division is 4885.20930232, and the remainder is 4.8e-08.
