We're dividing 49172640 by 946 
Let's see how many times 946 fits into 49172640.

On to step 1:
4 divided by 946 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 946

On to step 2:
When dividing 49 by 946, we get 0 with a remainder of 49.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 49, we get 49.
Fetch the next digit (1) from the dividend, attach it to 49 and continue: 491 / 946

Let's proceed to step 3:
946 can be fit into 491 0 times, resulting in a remainder of 491.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 491 leaves us with 491.
Bring next digit (7) of the dividend behind the 491 and repeat the process: 4917 / 946

Going ahead to step 4:
If we divide 4917 by 946, we get 5 and a remainder of 187.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we subtract 4730 from 4917, we get 187.
Take the next digit (2) from the dividend and append it to 187, then repeat: 1872 / 946

Let's proceed to step 5:
If we divide 1872 by 946, we get 1 and a remainder of 926.
The number 1 becomes the next digit in our result. 
Result so far: 51.0
Deduct 946 from 1872 and we're left with 926.
Fetch the next digit (6) from the dividend, attach it to 926 and continue: 9266 / 946

Moving on to step 6:
9266 divided by 946 is 9 with a remainder of 752.
Use 9 as the next digit of our solution. 
Result so far: 519.0
Subtracting 8514 from 9266 leaves us with 752.
Append the next digit (4) from the dividend to 752 and continue with: 7524 / 946

Going ahead to step 7:
If we divide 7524 by 946, we get 7 and a remainder of 902.
Put 7 as the next digit of the answer. 
Result so far: 5197.0
Deduct 6622 from 7524 and we're left with 902.
Append the next digit (0) from the dividend to 902 and continue with: 9020 / 946

Step 8:
946 can be fit into 9020 9 times, resulting in a remainder of 506.
The number 9 becomes the next digit in our result. 
Result so far: 51979.0
The remainder is 506 after subtracting 8514 from 9020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5060, and continue the process.

Advancing to step 9:
946 can be fit into 5060 5 times, resulting in a remainder of 330.
Record the quotient 5 as the next digit in the result. 
Result so far: 51979.5
Subtracting 4730 from 5060 leaves us with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Moving on to step 10:
If we divide 3300 by 946, we get 3 and a remainder of 462.
Record the quotient 3 as the next digit in the result. 
Result so far: 51979.53
If we take 2838 away from 3300, we end up with 462.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

Moving on to step 11:
If we divide 4620 by 946, we get 4 and a remainder of 836.
Record the quotient 4 as the next digit in the result. 
Result so far: 51979.534
If we subtract 3784 from 4620, we get 836.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8360, and continue the process.

Moving on to step 12:
946 goes into 8360 8 times with a remainder of 792.
Record the quotient 8 as the next digit in the result. 
Result so far: 51979.5348
The remainder is 792 after subtracting 7568 from 8360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7920, and continue the process.

Advancing to step 13:
When dividing 7920 by 946, we get 8 with a remainder of 352.
The next digit of our result is 8. 
Result so far: 51979.53488
Deduct 7568 from 7920 and we're left with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

The final result is 51979.53488 with a remainder of 0.000352.
