66058450 ÷ 946 
Our goal is to divide 66058450 by 946.

On to step 1:
946 goes into 6 0 times with 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.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 946

Going ahead to step 2:
The number 946 fits into 66 0 times, leaving a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Take the next digit (0) from the dividend and append it to 66, then repeat: 660 / 946

Step 3:
660 divided by 946 is 0 with a remainder of 660.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 660, we end up with 660.
Take the next digit (5) from the dividend and append it to 660, then repeat: 6605 / 946

Let's proceed to step 4:
946 goes into 6605 6 times with a remainder of 929.
The next digit of our result is 6. 
Result so far: 6.0
Subtract 5676 from 6605 to get 929.
Bring next digit (8) of the dividend behind the 929 and repeat the process: 9298 / 946

Advancing to step 5:
If we divide 9298 by 946, we get 9 and a remainder of 784.
Use 9 as the next digit of our solution. 
Result so far: 69.0
Subtracting 8514 from 9298 leaves us with 784.
Append the next digit (4) from the dividend to 784 and continue with: 7844 / 946

Let's proceed to step 6:
The number 946 fits into 7844 8 times, leaving a remainder of 276.
Put 8 as the next digit of the answer. 
Result so far: 698.0
Subtracting 7568 from 7844 leaves us with 276.
Bring next digit (5) of the dividend behind the 276 and repeat the process: 2765 / 946

Going ahead to step 7:
If we divide 2765 by 946, we get 2 and a remainder of 873.
The number 2 becomes the next digit in our result. 
Result so far: 6982.0
The remainder is 873 after subtracting 1892 from 2765.
Fetch the next digit (0) from the dividend, attach it to 873 and continue: 8730 / 946

Going ahead to step 8:
When dividing 8730 by 946, we get 9 with a remainder of 216.
Use 9 as the next digit of our solution. 
Result so far: 69829.0
Deduct 8514 from 8730 and we're left with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Advancing to step 9:
When dividing 2160 by 946, we get 2 with a remainder of 268.
The number 2 becomes the next digit in our result. 
Result so far: 69829.2
Subtract 1892 from 2160 to get 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Going ahead to step 10:
If we divide 2680 by 946, we get 2 and a remainder of 788.
The number 2 becomes the next digit in our result. 
Result so far: 69829.22
If we take 1892 away from 2680, we end up with 788.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7880, and continue the process.

The final result is 69829.22 with a remainder of 0.788.
