We're dividing 40383448 by 948 
We want to figure out the number of times 40383448 can be divided by 948.

On to step 1:
If we divide 4 by 948, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 948

Advancing to step 2:
948 can be fit into 40 0 times, resulting in a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Append the next digit (3) from the dividend to 40 and continue with: 403 / 948

Let's proceed to step 3:
403 divided by 948 is 0 with a remainder of 403.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 403 leaves us with 403.
Fetch the next digit (8) from the dividend, attach it to 403 and continue: 4038 / 948

Advancing to step 4:
If we divide 4038 by 948, we get 4 and a remainder of 246.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 3792 from 4038, we get 246.
Bring next digit (3) of the dividend behind the 246 and repeat the process: 2463 / 948

Moving on to step 5:
2463 divided by 948 is 2 with a remainder of 567.
The number 2 becomes the next digit in our result. 
Result so far: 42.0
Subtracting 1896 from 2463 leaves us with 567.
Include the next digit (4) from the dividend after 567, then repeat: 5674 / 948

Advancing to step 6:
5674 divided by 948 is 5 with a remainder of 934.
Put 5 as the next digit of the answer. 
Result so far: 425.0
The remainder is 934 after subtracting 4740 from 5674.
Append the next digit (4) from the dividend to 934 and continue with: 9344 / 948

Step 7:
9344 divided by 948 is 9 with a remainder of 812.
The number 9 becomes the next digit in our result. 
Result so far: 4259.0
Deduct 8532 from 9344 and we're left with 812.
Take the next digit (8) from the dividend and append it to 812, then repeat: 8128 / 948

Going ahead to step 8:
When dividing 8128 by 948, we get 8 with a remainder of 544.
Record the quotient 8 as the next digit in the result. 
Result so far: 42598.0
Subtracting 7584 from 8128 leaves us with 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Let's proceed to step 9:
5440 divided by 948 is 5 with a remainder of 700.
The number 5 becomes the next digit in our result. 
Result so far: 42598.5
Deduct 4740 from 5440 and we're left with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Going ahead to step 10:
948 can be fit into 7000 7 times, resulting in a remainder of 364.
The next digit of our result is 7. 
Result so far: 42598.57
Deduct 6636 from 7000 and we're left with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Step 11:
The number 948 fits into 3640 3 times, leaving a remainder of 796.
Write down 3 as next digit of the result. 
Result so far: 42598.573
If we take 2844 away from 3640, we end up with 796.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7960, and continue the process.

Let's proceed to step 12:
948 can be fit into 7960 8 times, resulting in a remainder of 376.
The number 8 becomes the next digit in our result. 
Result so far: 42598.5738
Subtract 7584 from 7960 to get 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Advancing to step 13:
The number 948 fits into 3760 3 times, leaving a remainder of 916.
Use 3 as the next digit of our solution. 
Result so far: 42598.57383
If we take 2844 away from 3760, we end up with 916.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9160, and continue the process.

Advancing to step 14:
The number 948 fits into 9160 9 times, leaving a remainder of 628.
Put 9 as the next digit of the answer. 
Result so far: 42598.573839
Subtracting 8532 from 9160 leaves us with 628.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6280, and continue the process.

On to step 15:
When dividing 6280 by 948, we get 6 with a remainder of 592.
Write down 6 as next digit of the result. 
Result so far: 42598.5738396
The remainder is 592 after subtracting 5688 from 6280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

Advancing to step 16:
When dividing 5920 by 948, we get 6 with a remainder of 232.
Record the quotient 6 as the next digit in the result. 
Result so far: 42598.57383966
Subtracting 5688 from 5920 leaves us with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

The final result is 42598.57383966 with a remainder of 2.32e-07.
