958641 ÷ 40 
Our goal is to divide 958641 by 40.

Step 1:
When dividing 9 by 40, we get 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (5) from the dividend and append it to 9, then repeat: 95 / 40

Moving on to step 2:
If we divide 95 by 40, we get 2 and a remainder of 15.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 80 from 95, we get 15.
Include the next digit (8) from the dividend after 15, then repeat: 158 / 40

Let's proceed to step 3:
40 can be fit into 158 3 times, resulting in a remainder of 38.
Use 3 as the next digit of our solution. 
Result so far: 23.0
If we subtract 120 from 158, we get 38.
Grab the next digit (6) from the dividend, add it to 38, then carry on: 386 / 40

Moving on to step 4:
The number 40 fits into 386 9 times, leaving a remainder of 26.
Write down 9 as next digit of the result. 
Result so far: 239.0
Deduct 360 from 386 and we're left with 26.
Fetch the next digit (4) from the dividend, attach it to 26 and continue: 264 / 40

Let's proceed to step 5:
When dividing 264 by 40, we get 6 with a remainder of 24.
The next digit of our result is 6. 
Result so far: 2396.0
Deduct 240 from 264 and we're left with 24.
Grab the next digit (1) from the dividend, add it to 24, then carry on: 241 / 40

Let's proceed to step 6:
241 divided by 40 is 6 with a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 23966.0
Subtracting 240 from 241 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
If we divide 10 by 40, we get 0 and a remainder of 10.
The next digit of our result is 0. 
Result so far: 23966.0
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
100 divided by 40 is 2 with a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 23966.02
Subtract 80 from 100 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 9:
40 goes into 200 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 23966.025
Deduct 200 from 200 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
40 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 23966.025
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 11:
If we divide 0 by 40, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 23966.025
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 23966.025, with a leftover of 0.0.
