Let's divide 661590 by 89
We want to divide 661590 by 89.

Let's proceed to step 1:
If we divide 6 by 89, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 89

Moving on to step 2:
The number 89 fits into 66 0 times, leaving a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Append the next digit (1) from the dividend to 66 and continue with: 661 / 89

Moving on to step 3:
When dividing 661 by 89, we get 7 with a remainder of 38.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtracting 623 from 661 leaves us with 38.
Include the next digit (5) from the dividend after 38, then repeat: 385 / 89

Step 4:
89 goes into 385 4 times with a remainder of 29.
Put 4 as the next digit of the answer. 
Result so far: 74.0
Subtracting 356 from 385 leaves us with 29.
Grab the next digit (9) from the dividend, add it to 29, then carry on: 299 / 89

Advancing to step 5:
89 can be fit into 299 3 times, resulting in a remainder of 32.
Record the quotient 3 as the next digit in the result. 
Result so far: 743.0
If we subtract 267 from 299, we get 32.
Take the next digit (0) from the dividend and append it to 32, then repeat: 320 / 89

Moving on to step 6:
The number 89 fits into 320 3 times, leaving a remainder of 53.
Use 3 as the next digit of our solution. 
Result so far: 7433.0
The remainder is 53 after subtracting 267 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Moving on to step 7:
If we divide 530 by 89, we get 5 and a remainder of 85.
The number 5 becomes the next digit in our result. 
Result so far: 7433.5
Subtract 445 from 530 to get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Step 8:
The number 89 fits into 850 9 times, leaving a remainder of 49.
The next digit of our result is 9. 
Result so far: 7433.59
If we take 801 away from 850, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 9:
89 goes into 490 5 times with a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 7433.595
Subtracting 445 from 490 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 10:
450 divided by 89 is 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 7433.5955
If we subtract 445 from 450, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Our division results in 7433.5955 with a remaining 5e-05.
