10121493 ÷ 435 
We want to figure out the number of times 10121493 can be divided by 435.

Let's proceed to step 1:
1 divided by 435 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 435

Let's proceed to step 2:
435 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 10, we end up with 10.
Bring next digit (1) of the dividend behind the 10 and repeat the process: 101 / 435

On to step 3:
When dividing 101 by 435, we get 0 with a remainder of 101.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 101 leaves us with 101.
Take the next digit (2) from the dividend and append it to 101, then repeat: 1012 / 435

Step 4:
The number 435 fits into 1012 2 times, leaving a remainder of 142.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 142 after subtracting 870 from 1012.
Take the next digit (1) from the dividend and append it to 142, then repeat: 1421 / 435

Step 5:
When dividing 1421 by 435, we get 3 with a remainder of 116.
Write down 3 as next digit of the result. 
Result so far: 23.0
Subtract 1305 from 1421 to get 116.
Include the next digit (4) from the dividend after 116, then repeat: 1164 / 435

Going ahead to step 6:
If we divide 1164 by 435, we get 2 and a remainder of 294.
Record the quotient 2 as the next digit in the result. 
Result so far: 232.0
Subtracting 870 from 1164 leaves us with 294.
Grab the next digit (9) from the dividend, add it to 294, then carry on: 2949 / 435

On to step 7:
If we divide 2949 by 435, we get 6 and a remainder of 339.
The next digit of our result is 6. 
Result so far: 2326.0
If we take 2610 away from 2949, we end up with 339.
Bring next digit (3) of the dividend behind the 339 and repeat the process: 3393 / 435

Going ahead to step 8:
435 goes into 3393 7 times with a remainder of 348.
Put 7 as the next digit of the answer. 
Result so far: 23267.0
The remainder is 348 after subtracting 3045 from 3393.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Moving on to step 9:
435 can be fit into 3480 8 times, resulting in a remainder of 0.
The next digit of our result is 8. 
Result so far: 23267.8
Deduct 3480 from 3480 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.

Step 10:
435 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 23267.8
The remainder is 0 after subtracting 0 from 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:
If we divide 0 by 435, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 23267.8
If we subtract 0 from 0, we 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.

The final result is 23267.8 with a remainder of 0.0.
