We look at the division of 42179814 by 247 
We're looking to find how many times 247 goes into 42179814.

Moving on to step 1:
247 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 247

Going ahead to step 2:
The number 247 fits into 42 0 times, leaving a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Grab the next digit (1) from the dividend, add it to 42, then carry on: 421 / 247

Advancing to step 3:
If we divide 421 by 247, we get 1 and a remainder of 174.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 247 from 421 and we're left with 174.
Bring next digit (7) of the dividend behind the 174 and repeat the process: 1747 / 247

Step 4:
247 can be fit into 1747 7 times, resulting in a remainder of 18.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
Subtracting 1729 from 1747 leaves us with 18.
Take the next digit (9) from the dividend and append it to 18, then repeat: 189 / 247

Advancing to step 5:
189 divided by 247 is 0 with a remainder of 189.
The next digit of our result is 0. 
Result so far: 170.0
Subtracting 0 from 189 leaves us with 189.
Include the next digit (8) from the dividend after 189, then repeat: 1898 / 247

Going ahead to step 6:
247 goes into 1898 7 times with a remainder of 169.
The number 7 becomes the next digit in our result. 
Result so far: 1707.0
If we take 1729 away from 1898, we end up with 169.
Include the next digit (1) from the dividend after 169, then repeat: 1691 / 247

Going ahead to step 7:
The number 247 fits into 1691 6 times, leaving a remainder of 209.
Use 6 as the next digit of our solution. 
Result so far: 17076.0
If we subtract 1482 from 1691, we get 209.
Bring next digit (4) of the dividend behind the 209 and repeat the process: 2094 / 247

Going ahead to step 8:
2094 divided by 247 is 8 with a remainder of 118.
Put 8 as the next digit of the answer. 
Result so far: 170768.0
The remainder is 118 after subtracting 1976 from 2094.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Step 9:
247 can be fit into 1180 4 times, resulting in a remainder of 192.
The number 4 becomes the next digit in our result. 
Result so far: 170768.4
Deduct 988 from 1180 and we're left with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

On to step 10:
1920 divided by 247 is 7 with a remainder of 191.
Use 7 as the next digit of our solution. 
Result so far: 170768.47
If we subtract 1729 from 1920, we get 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

Let's proceed to step 11:
1910 divided by 247 is 7 with a remainder of 181.
Write down 7 as next digit of the result. 
Result so far: 170768.477
The remainder is 181 after subtracting 1729 from 1910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

The final outcome is 170768.477, with a leftover of 0.0181.
