66580 divided by 59 
Our goal is to divide 66580 by 59.

Step 1:
When dividing 6 by 59, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 59

Moving on to step 2:
When dividing 66 by 59, we get 1 with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 59 from 66 and we're left with 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 59

Advancing to step 3:
59 can be fit into 75 1 times, resulting in a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Deduct 59 from 75 and we're left with 16.
Grab the next digit (8) from the dividend, add it to 16, then carry on: 168 / 59

Advancing to step 4:
If we divide 168 by 59, we get 2 and a remainder of 50.
Record the quotient 2 as the next digit in the result. 
Result so far: 112.0
Deduct 118 from 168 and we're left with 50.
Bring next digit (0) of the dividend behind the 50 and repeat the process: 500 / 59

Step 5:
If we divide 500 by 59, we get 8 and a remainder of 28.
Put 8 as the next digit of the answer. 
Result so far: 1128.0
Subtracting 472 from 500 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 6:
280 divided by 59 is 4 with a remainder of 44.
Use 4 as the next digit of our solution. 
Result so far: 1128.4
Deduct 236 from 280 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 7:
If we divide 440 by 59, we get 7 and a remainder of 27.
Record the quotient 7 as the next digit in the result. 
Result so far: 1128.47
Deduct 413 from 440 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 8:
270 divided by 59 is 4 with a remainder of 34.
Put 4 as the next digit of the answer. 
Result so far: 1128.474
The remainder is 34 after subtracting 236 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 9:
If we divide 340 by 59, we get 5 and a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 1128.4745
The remainder is 45 after subtracting 295 from 340.
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:
When dividing 450 by 59, we get 7 with a remainder of 37.
The next digit of our result is 7. 
Result so far: 1128.47457
Subtracting 413 from 450 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 11:
59 goes into 370 6 times with a remainder of 16.
The next digit of our result is 6. 
Result so far: 1128.474576
If we take 354 away from 370, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 12:
59 goes into 160 2 times with a remainder of 42.
Record the quotient 2 as the next digit in the result. 
Result so far: 1128.4745762
Subtract 118 from 160 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 13:
59 goes into 420 7 times with a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 1128.47457627
Subtracting 413 from 420 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

After the division, we end up with 1128.47457627 and a remainder of 7e-09.
