We look at the division of 351609 by 89 
Let's see how many times 89 fits into 351609.

Advancing to step 1:
89 can be fit into 3 0 times, resulting in 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.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 89

On to step 2:
89 can be fit into 35 0 times, resulting in a remainder of 35.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 35 and we're left with 35.
Include the next digit (1) from the dividend after 35, then repeat: 351 / 89

Let's proceed to step 3:
351 divided by 89 is 3 with a remainder of 84.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 267 from 351, we get 84.
Bring next digit (6) of the dividend behind the 84 and repeat the process: 846 / 89

Advancing to step 4:
When dividing 846 by 89, we get 9 with a remainder of 45.
Write down 9 as next digit of the result. 
Result so far: 39.0
The remainder is 45 after subtracting 801 from 846.
Take the next digit (0) from the dividend and append it to 45, then repeat: 450 / 89

Advancing to step 5:
89 can be fit into 450 5 times, resulting in a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 395.0
Deduct 445 from 450 and we're left with 5.
Bring next digit (9) of the dividend behind the 5 and repeat the process: 59 / 89

Moving on to step 6:
If we divide 59 by 89, we get 0 and a remainder of 59.
The number 0 becomes the next digit in our result. 
Result so far: 3950.0
Deduct 0 from 59 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 7:
590 divided by 89 is 6 with a remainder of 56.
The next digit of our result is 6. 
Result so far: 3950.6
Deduct 534 from 590 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 8:
560 divided by 89 is 6 with a remainder of 26.
Write down 6 as next digit of the result. 
Result so far: 3950.66
Subtracting 534 from 560 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The final result is 3950.66 with a remainder of 0.026.
