3589759 divided by 989 
We want to figure out the number of times 3589759 can be divided by 989.

Going ahead to step 1:
989 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 989

Step 2:
If we divide 35 by 989, we get 0 and a remainder of 35.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 35 to get 35.
Include the next digit (8) from the dividend after 35, then repeat: 358 / 989

On to step 3:
The number 989 fits into 358 0 times, leaving a remainder of 358.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 358, we get 358.
Include the next digit (9) from the dividend after 358, then repeat: 3589 / 989

On to step 4:
When dividing 3589 by 989, we get 3 with a remainder of 622.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 622 after subtracting 2967 from 3589.
Bring next digit (7) of the dividend behind the 622 and repeat the process: 6227 / 989

On to step 5:
989 can be fit into 6227 6 times, resulting in a remainder of 293.
Record the quotient 6 as the next digit in the result. 
Result so far: 36.0
Subtracting 5934 from 6227 leaves us with 293.
Append the next digit (5) from the dividend to 293 and continue with: 2935 / 989

Step 6:
989 can be fit into 2935 2 times, resulting in a remainder of 957.
Write down 2 as next digit of the result. 
Result so far: 362.0
If we take 1978 away from 2935, we end up with 957.
Grab the next digit (9) from the dividend, add it to 957, then carry on: 9579 / 989

Let's proceed to step 7:
If we divide 9579 by 989, we get 9 and a remainder of 678.
The next digit of our result is 9. 
Result so far: 3629.0
Deduct 8901 from 9579 and we're left with 678.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6780, and continue the process.

Let's proceed to step 8:
When dividing 6780 by 989, we get 6 with a remainder of 846.
Put 6 as the next digit of the answer. 
Result so far: 3629.6
The remainder is 846 after subtracting 5934 from 6780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8460, and continue the process.

Let's proceed to step 9:
When dividing 8460 by 989, we get 8 with a remainder of 548.
The number 8 becomes the next digit in our result. 
Result so far: 3629.68
Deduct 7912 from 8460 and we're left with 548.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

Going ahead to step 10:
If we divide 5480 by 989, we get 5 and a remainder of 535.
Record the quotient 5 as the next digit in the result. 
Result so far: 3629.685
If we subtract 4945 from 5480, we get 535.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5350, and continue the process.

Step 11:
If we divide 5350 by 989, we get 5 and a remainder of 405.
Put 5 as the next digit of the answer. 
Result so far: 3629.6855
If we subtract 4945 from 5350, we get 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

The final result is 3629.6855 with a remainder of 0.00405.
