66531570 ÷ 59 
We want to divide 66531570 by 59.

Moving on to step 1:
59 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 59

Going ahead to step 2:
When dividing 66 by 59, we get 1 with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 59 from 66 leaves us with 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 59

Advancing to step 3:
When dividing 75 by 59, we get 1 with a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we subtract 59 from 75, we get 16.
Bring next digit (3) of the dividend behind the 16 and repeat the process: 163 / 59

Step 4:
163 divided by 59 is 2 with a remainder of 45.
The next digit of our result is 2. 
Result so far: 112.0
Subtract 118 from 163 to get 45.
Append the next digit (1) from the dividend to 45 and continue with: 451 / 59

Let's proceed to step 5:
When dividing 451 by 59, we get 7 with a remainder of 38.
Use 7 as the next digit of our solution. 
Result so far: 1127.0
Subtract 413 from 451 to get 38.
Grab the next digit (5) from the dividend, add it to 38, then carry on: 385 / 59

Let's proceed to step 6:
If we divide 385 by 59, we get 6 and a remainder of 31.
The next digit of our result is 6. 
Result so far: 11276.0
Subtract 354 from 385 to get 31.
Append the next digit (7) from the dividend to 31 and continue with: 317 / 59

Advancing to step 7:
59 goes into 317 5 times with a remainder of 22.
Use 5 as the next digit of our solution. 
Result so far: 112765.0
If we take 295 away from 317, we end up with 22.
Fetch the next digit (0) from the dividend, attach it to 22 and continue: 220 / 59

Let's proceed to step 8:
59 goes into 220 3 times with a remainder of 43.
The number 3 becomes the next digit in our result. 
Result so far: 1127653.0
Subtract 177 from 220 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 9:
59 can be fit into 430 7 times, resulting in a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 1127653.7
If we take 413 away from 430, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 10:
59 goes into 170 2 times with a remainder of 52.
The number 2 becomes the next digit in our result. 
Result so far: 1127653.72
Subtract 118 from 170 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 11:
520 divided by 59 is 8 with a remainder of 48.
Put 8 as the next digit of the answer. 
Result so far: 1127653.728
Subtracting 472 from 520 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 12:
480 divided by 59 is 8 with a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 1127653.7288
If we subtract 472 from 480, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 1127653.7288 and a remainder of 8e-05.
