We're dividing 91579618 by 434 
We want to divide 91579618 by 434.

Going ahead to step 1:
The number 434 fits into 9 0 times, leaving a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 434

Going ahead to step 2:
The number 434 fits into 91 0 times, leaving a remainder of 91.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 91, we get 91.
Include the next digit (5) from the dividend after 91, then repeat: 915 / 434

Let's proceed to step 3:
915 divided by 434 is 2 with a remainder of 47.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 868 from 915, we get 47.
Grab the next digit (7) from the dividend, add it to 47, then carry on: 477 / 434

On to step 4:
If we divide 477 by 434, we get 1 and a remainder of 43.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
If we subtract 434 from 477, we get 43.
Append the next digit (9) from the dividend to 43 and continue with: 439 / 434

On to step 5:
When dividing 439 by 434, we get 1 with a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 211.0
Subtracting 434 from 439 leaves us with 5.
Take the next digit (6) from the dividend and append it to 5, then repeat: 56 / 434

Advancing to step 6:
When dividing 56 by 434, we get 0 with a remainder of 56.
Use 0 as the next digit of our solution. 
Result so far: 2110.0
Subtract 0 from 56 to get 56.
Fetch the next digit (1) from the dividend, attach it to 56 and continue: 561 / 434

Step 7:
The number 434 fits into 561 1 times, leaving a remainder of 127.
Put 1 as the next digit of the answer. 
Result so far: 21101.0
Subtracting 434 from 561 leaves us with 127.
Bring next digit (8) of the dividend behind the 127 and repeat the process: 1278 / 434

Let's proceed to step 8:
1278 divided by 434 is 2 with a remainder of 410.
Write down 2 as next digit of the result. 
Result so far: 211012.0
If we take 868 away from 1278, we end up with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Let's proceed to step 9:
4100 divided by 434 is 9 with a remainder of 194.
Write down 9 as next digit of the result. 
Result so far: 211012.9
If we subtract 3906 from 4100, we get 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Going ahead to step 10:
The number 434 fits into 1940 4 times, leaving a remainder of 204.
Use 4 as the next digit of our solution. 
Result so far: 211012.94
The remainder is 204 after subtracting 1736 from 1940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Step 11:
434 goes into 2040 4 times with a remainder of 304.
The number 4 becomes the next digit in our result. 
Result so far: 211012.944
Deduct 1736 from 2040 and we're left with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

The quotient of the division is 211012.944, and the remainder is 0.0304.
