We look at the division of 8402240 by 218 
We're looking to find how many times 218 goes into 8402240.

Going ahead to step 1:
8 divided by 218 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 218

Step 2:
The number 218 fits into 84 0 times, leaving a remainder of 84.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 84 after subtracting 0 from 84.
Fetch the next digit (0) from the dividend, attach it to 84 and continue: 840 / 218

Going ahead to step 3:
When dividing 840 by 218, we get 3 with a remainder of 186.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 186 after subtracting 654 from 840.
Grab the next digit (2) from the dividend, add it to 186, then carry on: 1862 / 218

Advancing to step 4:
1862 divided by 218 is 8 with a remainder of 118.
The number 8 becomes the next digit in our result. 
Result so far: 38.0
If we subtract 1744 from 1862, we get 118.
Append the next digit (2) from the dividend to 118 and continue with: 1182 / 218

On to step 5:
The number 218 fits into 1182 5 times, leaving a remainder of 92.
Put 5 as the next digit of the answer. 
Result so far: 385.0
The remainder is 92 after subtracting 1090 from 1182.
Include the next digit (4) from the dividend after 92, then repeat: 924 / 218

Advancing to step 6:
924 divided by 218 is 4 with a remainder of 52.
Record the quotient 4 as the next digit in the result. 
Result so far: 3854.0
If we take 872 away from 924, we end up with 52.
Bring next digit (0) of the dividend behind the 52 and repeat the process: 520 / 218

Moving on to step 7:
The number 218 fits into 520 2 times, leaving a remainder of 84.
Use 2 as the next digit of our solution. 
Result so far: 38542.0
Subtracting 436 from 520 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 8:
If we divide 840 by 218, we get 3 and a remainder of 186.
Write down 3 as next digit of the result. 
Result so far: 38542.3
If we subtract 654 from 840, we get 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Advancing to step 9:
The number 218 fits into 1860 8 times, leaving a remainder of 116.
Put 8 as the next digit of the answer. 
Result so far: 38542.38
Subtract 1744 from 1860 to get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Going ahead to step 10:
1160 divided by 218 is 5 with a remainder of 70.
Record the quotient 5 as the next digit in the result. 
Result so far: 38542.385
Subtracting 1090 from 1160 leaves us 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.

Going ahead to step 11:
The number 218 fits into 700 3 times, leaving a remainder of 46.
The number 3 becomes the next digit in our result. 
Result so far: 38542.3853
If we take 654 away from 700, we end up 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.

Moving on to step 12:
218 can be fit into 460 2 times, resulting in a remainder of 24.
The next digit of our result is 2. 
Result so far: 38542.38532
Deduct 436 from 460 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 13:
218 can be fit into 240 1 times, resulting in a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 38542.385321
If we subtract 218 from 240, 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.

Advancing to step 14:
218 goes into 220 1 times with a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 38542.3853211
If we take 218 away from 220, 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.

Our division results in 38542.3853211 with a remaining 2e-08.
