We look at the division of 420226 by 87 
We want to divide 420226 by 87.

On to step 1:
4 divided by 87 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 87

Step 2:
When dividing 42 by 87, we get 0 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.
Grab the next digit (0) from the dividend, add it to 42, then carry on: 420 / 87

Advancing to step 3:
420 divided by 87 is 4 with a remainder of 72.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 348 away from 420, we end up with 72.
Bring next digit (2) of the dividend behind the 72 and repeat the process: 722 / 87

Going ahead to step 4:
When dividing 722 by 87, we get 8 with a remainder of 26.
The next digit of our result is 8. 
Result so far: 48.0
The remainder is 26 after subtracting 696 from 722.
Grab the next digit (2) from the dividend, add it to 26, then carry on: 262 / 87

Going ahead to step 5:
262 divided by 87 is 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 483.0
The remainder is 1 after subtracting 261 from 262.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 87

Advancing to step 6:
When dividing 16 by 87, we get 0 with a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 4830.0
If we take 0 away from 16, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 7:
87 can be fit into 160 1 times, resulting in a remainder of 73.
Put 1 as the next digit of the answer. 
Result so far: 4830.1
Deduct 87 from 160 and we're left with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

On to step 8:
When dividing 730 by 87, we get 8 with a remainder of 34.
Use 8 as the next digit of our solution. 
Result so far: 4830.18
If we subtract 696 from 730, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 9:
340 divided by 87 is 3 with a remainder of 79.
Put 3 as the next digit of the answer. 
Result so far: 4830.183
Deduct 261 from 340 and we're left with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Moving on to step 10:
The number 87 fits into 790 9 times, leaving a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 4830.1839
The remainder is 7 after subtracting 783 from 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 11:
When dividing 70 by 87, we get 0 with a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 4830.1839
Subtract 0 from 70 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 12:
87 goes into 700 8 times with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 4830.183908
Subtract 696 from 700 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 13:
40 divided by 87 is 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 4830.183908
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 14:
The number 87 fits into 400 4 times, leaving a remainder of 52.
Use 4 as the next digit of our solution. 
Result so far: 4830.18390804
If we subtract 348 from 400, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Our division results in 4830.18390804 with a remaining 5.2e-08.
