Let's divide 85643820 by 331
Our goal is to divide 85643820 by 331.

Going ahead to step 1:
When dividing 8 by 331, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 331

On to step 2:
The number 331 fits into 85 0 times, leaving a remainder of 85.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 85 and we're left with 85.
Grab the next digit (6) from the dividend, add it to 85, then carry on: 856 / 331

Let's proceed to step 3:
The number 331 fits into 856 2 times, leaving a remainder of 194.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 662 from 856, we get 194.
Grab the next digit (4) from the dividend, add it to 194, then carry on: 1944 / 331

Step 4:
The number 331 fits into 1944 5 times, leaving a remainder of 289.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
Subtract 1655 from 1944 to get 289.
Grab the next digit (3) from the dividend, add it to 289, then carry on: 2893 / 331

Step 5:
When dividing 2893 by 331, we get 8 with a remainder of 245.
The next digit of our result is 8. 
Result so far: 258.0
Subtract 2648 from 2893 to get 245.
Include the next digit (8) from the dividend after 245, then repeat: 2458 / 331

Moving on to step 6:
If we divide 2458 by 331, we get 7 and a remainder of 141.
Record the quotient 7 as the next digit in the result. 
Result so far: 2587.0
Subtract 2317 from 2458 to get 141.
Grab the next digit (2) from the dividend, add it to 141, then carry on: 1412 / 331

Step 7:
If we divide 1412 by 331, we get 4 and a remainder of 88.
Put 4 as the next digit of the answer. 
Result so far: 25874.0
If we take 1324 away from 1412, we end up with 88.
Include the next digit (0) from the dividend after 88, then repeat: 880 / 331

Advancing to step 8:
If we divide 880 by 331, we get 2 and a remainder of 218.
Use 2 as the next digit of our solution. 
Result so far: 258742.0
Subtracting 662 from 880 leaves us with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Moving on to step 9:
If we divide 2180 by 331, we get 6 and a remainder of 194.
Write down 6 as next digit of the result. 
Result so far: 258742.6
Deduct 1986 from 2180 and we're left with 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Moving on to step 10:
When dividing 1940 by 331, we get 5 with a remainder of 285.
Write down 5 as next digit of the result. 
Result so far: 258742.65
The remainder is 285 after subtracting 1655 from 1940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Let's proceed to step 11:
331 goes into 2850 8 times with a remainder of 202.
The number 8 becomes the next digit in our result. 
Result so far: 258742.658
If we take 2648 away from 2850, we end up with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Going ahead to step 12:
If we divide 2020 by 331, we get 6 and a remainder of 34.
Write down 6 as next digit of the result. 
Result so far: 258742.6586
If we take 1986 away from 2020, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 13:
The number 331 fits into 340 1 times, leaving a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 258742.65861
If we take 331 away from 340, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 14:
The number 331 fits into 90 0 times, leaving a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 258742.65861
If we take 0 away from 90, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 15:
The number 331 fits into 900 2 times, leaving a remainder of 238.
The next digit of our result is 2. 
Result so far: 258742.6586102
Subtract 662 from 900 to get 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Let's proceed to step 16:
331 goes into 2380 7 times with a remainder of 63.
Put 7 as the next digit of the answer. 
Result so far: 258742.65861027
Deduct 2317 from 2380 and we're left with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

The final outcome is 258742.65861027, with a leftover of 6.3e-08.
