We're dividing 78446484 by 331 
Let's see how many times 331 fits into 78446484.

Moving on to step 1:
331 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 331

Moving on to step 2:
When dividing 78 by 331, we get 0 with a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Include the next digit (4) from the dividend after 78, then repeat: 784 / 331

Going ahead to step 3:
When dividing 784 by 331, we get 2 with a remainder of 122.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 662 from 784 and we're left with 122.
Take the next digit (4) from the dividend and append it to 122, then repeat: 1224 / 331

On to step 4:
When dividing 1224 by 331, we get 3 with a remainder of 231.
Write down 3 as next digit of the result. 
Result so far: 23.0
Subtracting 993 from 1224 leaves us with 231.
Include the next digit (6) from the dividend after 231, then repeat: 2316 / 331

Let's proceed to step 5:
If we divide 2316 by 331, we get 6 and a remainder of 330.
Write down 6 as next digit of the result. 
Result so far: 236.0
The remainder is 330 after subtracting 1986 from 2316.
Fetch the next digit (4) from the dividend, attach it to 330 and continue: 3304 / 331

Let's proceed to step 6:
When dividing 3304 by 331, we get 9 with a remainder of 325.
Write down 9 as next digit of the result. 
Result so far: 2369.0
The remainder is 325 after subtracting 2979 from 3304.
Grab the next digit (8) from the dividend, add it to 325, then carry on: 3258 / 331

On to step 7:
When dividing 3258 by 331, we get 9 with a remainder of 279.
The number 9 becomes the next digit in our result. 
Result so far: 23699.0
If we take 2979 away from 3258, we end up with 279.
Fetch the next digit (4) from the dividend, attach it to 279 and continue: 2794 / 331

Going ahead to step 8:
If we divide 2794 by 331, we get 8 and a remainder of 146.
Write down 8 as next digit of the result. 
Result so far: 236998.0
Deduct 2648 from 2794 and we're left with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Advancing to step 9:
If we divide 1460 by 331, we get 4 and a remainder of 136.
Use 4 as the next digit of our solution. 
Result so far: 236998.4
Subtract 1324 from 1460 to get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Advancing to step 10:
When dividing 1360 by 331, we get 4 with a remainder of 36.
The next digit of our result is 4. 
Result so far: 236998.44
The remainder is 36 after subtracting 1324 from 1360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

After the division, we end up with 236998.44 and a remainder of 0.036.
