We look at the division of 311639 by 89 
We want to divide 311639 by 89.

On to step 1:
89 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 89

Step 2:
The number 89 fits into 31 0 times, leaving a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Grab the next digit (1) from the dividend, add it to 31, then carry on: 311 / 89

Moving on to step 3:
When dividing 311 by 89, we get 3 with a remainder of 44.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 267 away from 311, we end up with 44.
Append the next digit (6) from the dividend to 44 and continue with: 446 / 89

Moving on to step 4:
89 goes into 446 5 times with a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 35.0
Deduct 445 from 446 and we're left with 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 89

Advancing to step 5:
89 goes into 13 0 times with a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 350.0
The remainder is 13 after subtracting 0 from 13.
Bring next digit (9) of the dividend behind the 13 and repeat the process: 139 / 89

Advancing to step 6:
When dividing 139 by 89, we get 1 with a remainder of 50.
Use 1 as the next digit of our solution. 
Result so far: 3501.0
Deduct 89 from 139 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 7:
If we divide 500 by 89, we get 5 and a remainder of 55.
The next digit of our result is 5. 
Result so far: 3501.5
Deduct 445 from 500 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 8:
When dividing 550 by 89, we get 6 with a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 3501.56
Deduct 534 from 550 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 9:
If we divide 160 by 89, we get 1 and a remainder of 71.
Record the quotient 1 as the next digit in the result. 
Result so far: 3501.561
If we subtract 89 from 160, we get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Moving on to step 10:
The number 89 fits into 710 7 times, leaving a remainder of 87.
The number 7 becomes the next digit in our result. 
Result so far: 3501.5617
Subtracting 623 from 710 leaves us with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Advancing to step 11:
The number 89 fits into 870 9 times, leaving a remainder of 69.
The number 9 becomes the next digit in our result. 
Result so far: 3501.56179
Subtracting 801 from 870 leaves us with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Let's proceed to step 12:
89 goes into 690 7 times with a remainder of 67.
Use 7 as the next digit of our solution. 
Result so far: 3501.561797
Subtract 623 from 690 to get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

On to step 13:
89 can be fit into 670 7 times, resulting in a remainder of 47.
Record the quotient 7 as the next digit in the result. 
Result so far: 3501.5617977
Subtracting 623 from 670 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

The final result is 3501.5617977 with a remainder of 4.7e-07.
