We divide 72378831 by 435
We want to divide 72378831 by 435.

Let's proceed to step 1:
If we divide 7 by 435, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 435

Going ahead to step 2:
When dividing 72 by 435, we get 0 with a remainder of 72.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 72, we end up with 72.
Grab the next digit (3) from the dividend, add it to 72, then carry on: 723 / 435

Step 3:
If we divide 723 by 435, we get 1 and a remainder of 288.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 435 from 723 leaves us with 288.
Bring next digit (7) of the dividend behind the 288 and repeat the process: 2887 / 435

Advancing to step 4:
435 can be fit into 2887 6 times, resulting in a remainder of 277.
Write down 6 as next digit of the result. 
Result so far: 16.0
Deduct 2610 from 2887 and we're left with 277.
Bring next digit (8) of the dividend behind the 277 and repeat the process: 2778 / 435

Let's proceed to step 5:
When dividing 2778 by 435, we get 6 with a remainder of 168.
Write down 6 as next digit of the result. 
Result so far: 166.0
Subtracting 2610 from 2778 leaves us with 168.
Grab the next digit (8) from the dividend, add it to 168, then carry on: 1688 / 435

Moving on to step 6:
1688 divided by 435 is 3 with a remainder of 383.
Record the quotient 3 as the next digit in the result. 
Result so far: 1663.0
Deduct 1305 from 1688 and we're left with 383.
Fetch the next digit (3) from the dividend, attach it to 383 and continue: 3833 / 435

Moving on to step 7:
435 can be fit into 3833 8 times, resulting in a remainder of 353.
Put 8 as the next digit of the answer. 
Result so far: 16638.0
Subtract 3480 from 3833 to get 353.
Grab the next digit (1) from the dividend, add it to 353, then carry on: 3531 / 435

Moving on to step 8:
The number 435 fits into 3531 8 times, leaving a remainder of 51.
Use 8 as the next digit of our solution. 
Result so far: 166388.0
Subtracting 3480 from 3531 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 9:
510 divided by 435 is 1 with a remainder of 75.
Write down 1 as next digit of the result. 
Result so far: 166388.1
Subtract 435 from 510 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 10:
435 goes into 750 1 times with a remainder of 315.
The next digit of our result is 1. 
Result so far: 166388.11
Subtract 435 from 750 to get 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

After the division, we end up with 166388.11 and a remainder of 0.315.
