We're dividing 1639643 by 289 
Let's see how many times 289 fits into 1639643.

Going ahead to step 1:
1 divided by 289 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 289

Going ahead to step 2:
If we divide 16 by 289, we get 0 and a remainder of 16.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 16 and we're left with 16.
Include the next digit (3) from the dividend after 16, then repeat: 163 / 289

Let's proceed to step 3:
289 goes into 163 0 times with a remainder of 163.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 163 and we're left with 163.
Grab the next digit (9) from the dividend, add it to 163, then carry on: 1639 / 289

Advancing to step 4:
The number 289 fits into 1639 5 times, leaving a remainder of 194.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 194 after subtracting 1445 from 1639.
Append the next digit (6) from the dividend to 194 and continue with: 1946 / 289

Let's proceed to step 5:
289 can be fit into 1946 6 times, resulting in a remainder of 212.
Record the quotient 6 as the next digit in the result. 
Result so far: 56.0
If we subtract 1734 from 1946, we get 212.
Grab the next digit (4) from the dividend, add it to 212, then carry on: 2124 / 289

On to step 6:
If we divide 2124 by 289, we get 7 and a remainder of 101.
The next digit of our result is 7. 
Result so far: 567.0
If we take 2023 away from 2124, we end up with 101.
Include the next digit (3) from the dividend after 101, then repeat: 1013 / 289

Let's proceed to step 7:
When dividing 1013 by 289, we get 3 with a remainder of 146.
Put 3 as the next digit of the answer. 
Result so far: 5673.0
If we subtract 867 from 1013, we get 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Let's proceed to step 8:
289 can be fit into 1460 5 times, resulting in a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 5673.5
If we take 1445 away from 1460, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 9:
289 goes into 150 0 times with a remainder of 150.
Put 0 as the next digit of the answer. 
Result so far: 5673.5
If we subtract 0 from 150, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Let's proceed to step 10:
289 can be fit into 1500 5 times, resulting in a remainder of 55.
The next digit of our result is 5. 
Result so far: 5673.505
The remainder is 55 after subtracting 1445 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 11:
When dividing 550 by 289, we get 1 with a remainder of 261.
The next digit of our result is 1. 
Result so far: 5673.5051
Deduct 289 from 550 and we're left with 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

Let's proceed to step 12:
If we divide 2610 by 289, we get 9 and a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 5673.50519
The remainder is 9 after subtracting 2601 from 2610.
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 13:
289 goes into 90 0 times with a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 5673.50519
Deduct 0 from 90 and we're left 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.

Step 14:
289 can be fit into 900 3 times, resulting in a remainder of 33.
The number 3 becomes the next digit in our result. 
Result so far: 5673.5051903
Deduct 867 from 900 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 15:
330 divided by 289 is 1 with a remainder of 41.
The next digit of our result is 1. 
Result so far: 5673.50519031
The remainder is 41 after subtracting 289 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Our division results in 5673.50519031 with a remaining 4.1e-08.
