We look at the division of 40489236 by 948 
We want to figure out the number of times 40489236 can be divided by 948.

Step 1:
If we divide 4 by 948, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 948

Advancing to step 2:
The number 948 fits into 40 0 times, leaving a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Grab the next digit (4) from the dividend, add it to 40, then carry on: 404 / 948

Step 3:
948 can be fit into 404 0 times, resulting in a remainder of 404.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 404 after subtracting 0 from 404.
Append the next digit (8) from the dividend to 404 and continue with: 4048 / 948

Let's proceed to step 4:
If we divide 4048 by 948, we get 4 and a remainder of 256.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 3792 from 4048 leaves us with 256.
Append the next digit (9) from the dividend to 256 and continue with: 2569 / 948

Moving on to step 5:
When dividing 2569 by 948, we get 2 with a remainder of 673.
Record the quotient 2 as the next digit in the result. 
Result so far: 42.0
If we subtract 1896 from 2569, we get 673.
Fetch the next digit (2) from the dividend, attach it to 673 and continue: 6732 / 948

On to step 6:
When dividing 6732 by 948, we get 7 with a remainder of 96.
Record the quotient 7 as the next digit in the result. 
Result so far: 427.0
Subtracting 6636 from 6732 leaves us with 96.
Append the next digit (3) from the dividend to 96 and continue with: 963 / 948

Moving on to step 7:
The number 948 fits into 963 1 times, leaving a remainder of 15.
The next digit of our result is 1. 
Result so far: 4271.0
The remainder is 15 after subtracting 948 from 963.
Include the next digit (6) from the dividend after 15, then repeat: 156 / 948

Advancing to step 8:
When dividing 156 by 948, we get 0 with a remainder of 156.
Use 0 as the next digit of our solution. 
Result so far: 42710.0
Deduct 0 from 156 and we're left with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Advancing to step 9:
If we divide 1560 by 948, we get 1 and a remainder of 612.
The number 1 becomes the next digit in our result. 
Result so far: 42710.1
If we take 948 away from 1560, we end up with 612.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6120, and continue the process.

Going ahead to step 10:
The number 948 fits into 6120 6 times, leaving a remainder of 432.
The number 6 becomes the next digit in our result. 
Result so far: 42710.16
If we subtract 5688 from 6120, we get 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Advancing to step 11:
948 can be fit into 4320 4 times, resulting in a remainder of 528.
Write down 4 as next digit of the result. 
Result so far: 42710.164
If we subtract 3792 from 4320, we get 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Let's proceed to step 12:
948 can be fit into 5280 5 times, resulting in a remainder of 540.
Put 5 as the next digit of the answer. 
Result so far: 42710.1645
If we take 4740 away from 5280, we end up with 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Advancing to step 13:
If we divide 5400 by 948, we get 5 and a remainder of 660.
The next digit of our result is 5. 
Result so far: 42710.16455
Deduct 4740 from 5400 and we're left with 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Our division results in 42710.16455 with a remaining 0.00066.
