Let's divide 78981000 by 331
We want to divide 78981000 by 331.

Step 1:
When dividing 7 by 331, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 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
Subtract 0 from 78 to get 78.
Take the next digit (9) from the dividend and append it to 78, then repeat: 789 / 331

On to step 3:
When dividing 789 by 331, we get 2 with a remainder of 127.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 662 from 789 to get 127.
Append the next digit (8) from the dividend to 127 and continue with: 1278 / 331

Going ahead to step 4:
When dividing 1278 by 331, we get 3 with a remainder of 285.
Put 3 as the next digit of the answer. 
Result so far: 23.0
If we take 993 away from 1278, we end up with 285.
Grab the next digit (1) from the dividend, add it to 285, then carry on: 2851 / 331

Advancing to step 5:
The number 331 fits into 2851 8 times, leaving a remainder of 203.
Record the quotient 8 as the next digit in the result. 
Result so far: 238.0
Deduct 2648 from 2851 and we're left with 203.
Fetch the next digit (0) from the dividend, attach it to 203 and continue: 2030 / 331

Advancing to step 6:
331 goes into 2030 6 times with a remainder of 44.
The number 6 becomes the next digit in our result. 
Result so far: 2386.0
If we take 1986 away from 2030, we end up with 44.
Grab the next digit (0) from the dividend, add it to 44, then carry on: 440 / 331

Advancing to step 7:
If we divide 440 by 331, we get 1 and a remainder of 109.
The next digit of our result is 1. 
Result so far: 23861.0
If we subtract 331 from 440, we get 109.
Include the next digit (0) from the dividend after 109, then repeat: 1090 / 331

Step 8:
331 goes into 1090 3 times with a remainder of 97.
Record the quotient 3 as the next digit in the result. 
Result so far: 238613.0
Subtract 993 from 1090 to get 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Step 9:
The number 331 fits into 970 2 times, leaving a remainder of 308.
The number 2 becomes the next digit in our result. 
Result so far: 238613.2
Subtract 662 from 970 to get 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Let's proceed to step 10:
When dividing 3080 by 331, we get 9 with a remainder of 101.
The next digit of our result is 9. 
Result so far: 238613.29
Subtract 2979 from 3080 to get 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

On to step 11:
1010 divided by 331 is 3 with a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 238613.293
If we subtract 993 from 1010, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 12:
331 can be fit into 170 0 times, resulting in a remainder of 170.
The next digit of our result is 0. 
Result so far: 238613.293
If we take 0 away from 170, we end up with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Let's proceed to step 13:
1700 divided by 331 is 5 with a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 238613.29305
Subtract 1655 from 1700 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 14:
If we divide 450 by 331, we get 1 and a remainder of 119.
Record the quotient 1 as the next digit in the result. 
Result so far: 238613.293051
Subtract 331 from 450 to get 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Moving on to step 15:
If we divide 1190 by 331, we get 3 and a remainder of 197.
Use 3 as the next digit of our solution. 
Result so far: 238613.2930513
Subtract 993 from 1190 to get 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Let's proceed to step 16:
331 can be fit into 1970 5 times, resulting in a remainder of 315.
Write down 5 as next digit of the result. 
Result so far: 238613.29305135
Subtract 1655 from 1970 to get 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

The final outcome is 238613.29305135, with a leftover of 3.15e-07.
