712451 divided by 40 
We want to divide 712451 by 40.

Going ahead to step 1:
When dividing 7 by 40, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 40

Step 2:
40 can be fit into 71 1 times, resulting in a remainder of 31.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 31 after subtracting 40 from 71.
Append the next digit (2) from the dividend to 31 and continue with: 312 / 40

Step 3:
312 divided by 40 is 7 with a remainder of 32.
The next digit of our result is 7. 
Result so far: 17.0
The remainder is 32 after subtracting 280 from 312.
Take the next digit (4) from the dividend and append it to 32, then repeat: 324 / 40

Advancing to step 4:
40 goes into 324 8 times with a remainder of 4.
The next digit of our result is 8. 
Result so far: 178.0
Subtracting 320 from 324 leaves us with 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 40

Moving on to step 5:
When dividing 45 by 40, we get 1 with a remainder of 5.
The next digit of our result is 1. 
Result so far: 1781.0
Subtracting 40 from 45 leaves us with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 40

Advancing to step 6:
If we divide 51 by 40, we get 1 and a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 17811.0
If we take 40 away from 51, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 7:
When dividing 110 by 40, we get 2 with a remainder of 30.
Use 2 as the next digit of our solution. 
Result so far: 17811.2
Deduct 80 from 110 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 8:
If we divide 300 by 40, we get 7 and a remainder of 20.
Use 7 as the next digit of our solution. 
Result so far: 17811.27
Deduct 280 from 300 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
When dividing 200 by 40, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 17811.275
The remainder is 0 after subtracting 200 from 200.
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:
If we divide 0 by 40, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 17811.275
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 11:
0 divided by 40 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 17811.275
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 quotient of the division is 17811.275, and the remainder is 0.0.
