78910124 ÷ 242 
We want to divide 78910124 by 242.

Advancing to step 1:
If we divide 7 by 242, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 242

Going ahead to step 2:
When dividing 78 by 242, we get 0 with a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Include the next digit (9) from the dividend after 78, then repeat: 789 / 242

Step 3:
If we divide 789 by 242, we get 3 and a remainder of 63.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 726 from 789, we get 63.
Fetch the next digit (1) from the dividend, attach it to 63 and continue: 631 / 242

Let's proceed to step 4:
If we divide 631 by 242, we get 2 and a remainder of 147.
Put 2 as the next digit of the answer. 
Result so far: 32.0
Subtract 484 from 631 to get 147.
Grab the next digit (0) from the dividend, add it to 147, then carry on: 1470 / 242

Let's proceed to step 5:
If we divide 1470 by 242, we get 6 and a remainder of 18.
Record the quotient 6 as the next digit in the result. 
Result so far: 326.0
If we subtract 1452 from 1470, we get 18.
Bring next digit (1) of the dividend behind the 18 and repeat the process: 181 / 242

Advancing to step 6:
181 divided by 242 is 0 with a remainder of 181.
Record the quotient 0 as the next digit in the result. 
Result so far: 3260.0
If we subtract 0 from 181, we get 181.
Include the next digit (2) from the dividend after 181, then repeat: 1812 / 242

Moving on to step 7:
1812 divided by 242 is 7 with a remainder of 118.
Put 7 as the next digit of the answer. 
Result so far: 32607.0
Deduct 1694 from 1812 and we're left with 118.
Fetch the next digit (4) from the dividend, attach it to 118 and continue: 1184 / 242

Step 8:
242 can be fit into 1184 4 times, resulting in a remainder of 216.
Write down 4 as next digit of the result. 
Result so far: 326074.0
If we subtract 968 from 1184, we get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Advancing to step 9:
If we divide 2160 by 242, we get 8 and a remainder of 224.
Use 8 as the next digit of our solution. 
Result so far: 326074.8
Subtracting 1936 from 2160 leaves us with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Step 10:
242 goes into 2240 9 times with a remainder of 62.
The next digit of our result is 9. 
Result so far: 326074.89
Deduct 2178 from 2240 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.

Step 11:
When dividing 620 by 242, we get 2 with a remainder of 136.
The number 2 becomes the next digit in our result. 
Result so far: 326074.892
Subtracting 484 from 620 leaves us with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Going ahead to step 12:
When dividing 1360 by 242, we get 5 with a remainder of 150.
Put 5 as the next digit of the answer. 
Result so far: 326074.8925
The remainder is 150 after subtracting 1210 from 1360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Let's proceed to step 13:
1500 divided by 242 is 6 with a remainder of 48.
The number 6 becomes the next digit in our result. 
Result so far: 326074.89256
The remainder is 48 after subtracting 1452 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 14:
242 can be fit into 480 1 times, resulting in a remainder of 238.
Put 1 as the next digit of the answer. 
Result so far: 326074.892561
Deduct 242 from 480 and we're left with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Moving on to step 15:
242 can be fit into 2380 9 times, resulting in a remainder of 202.
Write down 9 as next digit of the result. 
Result so far: 326074.8925619
If we subtract 2178 from 2380, we get 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Step 16:
When dividing 2020 by 242, we get 8 with a remainder of 84.
Write down 8 as next digit of the result. 
Result so far: 326074.89256198
Subtract 1936 from 2020 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

After the division, we end up with 326074.89256198 and a remainder of 8.4e-08.
