We're dividing 391397 by 89 
Let's see how many times 89 fits into 391397.

Advancing to step 1:
If we divide 3 by 89, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 89

Step 2:
If we divide 39 by 89, we get 0 and a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Bring next digit (1) of the dividend behind the 39 and repeat the process: 391 / 89

Step 3:
When dividing 391 by 89, we get 4 with a remainder of 35.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 35 after subtracting 356 from 391.
Grab the next digit (3) from the dividend, add it to 35, then carry on: 353 / 89

Step 4:
When dividing 353 by 89, we get 3 with a remainder of 86.
The next digit of our result is 3. 
Result so far: 43.0
If we take 267 away from 353, we end up with 86.
Fetch the next digit (9) from the dividend, attach it to 86 and continue: 869 / 89

Let's proceed to step 5:
The number 89 fits into 869 9 times, leaving a remainder of 68.
The next digit of our result is 9. 
Result so far: 439.0
Deduct 801 from 869 and we're left with 68.
Grab the next digit (7) from the dividend, add it to 68, then carry on: 687 / 89

Advancing to step 6:
When dividing 687 by 89, we get 7 with a remainder of 64.
Record the quotient 7 as the next digit in the result. 
Result so far: 4397.0
The remainder is 64 after subtracting 623 from 687.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 7:
640 divided by 89 is 7 with a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 4397.7
If we take 623 away from 640, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 8:
If we divide 170 by 89, we get 1 and a remainder of 81.
Use 1 as the next digit of our solution. 
Result so far: 4397.71
Subtracting 89 from 170 leaves us with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Going ahead to step 9:
89 can be fit into 810 9 times, resulting in a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 4397.719
If we take 801 away from 810, 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.

Moving on to step 10:
89 goes into 90 1 times with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 4397.7191
Subtracting 89 from 90 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 11:
89 goes into 10 0 times with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 4397.7191
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 12:
89 can be fit into 100 1 times, resulting in a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 4397.719101
If we subtract 89 from 100, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 13:
If we divide 110 by 89, we get 1 and a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 4397.7191011
If we take 89 away from 110, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

The quotient of the division is 4397.7191011, and the remainder is 2.1e-07.
