91347749 ÷ 434 
We want to figure out the number of times 91347749 can be divided 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
Subtracting 0 from 9 leaves us with 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 434

Let's proceed to step 2:
When dividing 91 by 434, we get 0 with a remainder of 91.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 91, we get 91.
Include the next digit (3) from the dividend after 91, then repeat: 913 / 434

Let's proceed to step 3:
913 divided by 434 is 2 with a remainder of 45.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 868 from 913 leaves us with 45.
Append the next digit (4) from the dividend to 45 and continue with: 454 / 434

Going ahead to step 4:
If we divide 454 by 434, we get 1 and a remainder of 20.
Use 1 as the next digit of our solution. 
Result so far: 21.0
If we subtract 434 from 454, we get 20.
Take the next digit (7) from the dividend and append it to 20, then repeat: 207 / 434

Going ahead to step 5:
434 goes into 207 0 times with a remainder of 207.
The next digit of our result is 0. 
Result so far: 210.0
Subtracting 0 from 207 leaves us with 207.
Bring next digit (7) of the dividend behind the 207 and repeat the process: 2077 / 434

Moving on to step 6:
When dividing 2077 by 434, we get 4 with a remainder of 341.
The next digit of our result is 4. 
Result so far: 2104.0
If we subtract 1736 from 2077, we get 341.
Include the next digit (4) from the dividend after 341, then repeat: 3414 / 434

Moving on to step 7:
When dividing 3414 by 434, we get 7 with a remainder of 376.
Record the quotient 7 as the next digit in the result. 
Result so far: 21047.0
Deduct 3038 from 3414 and we're left with 376.
Fetch the next digit (9) from the dividend, attach it to 376 and continue: 3769 / 434

Going ahead to step 8:
3769 divided by 434 is 8 with a remainder of 297.
Write down 8 as next digit of the result. 
Result so far: 210478.0
If we take 3472 away from 3769, we end up with 297.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2970, and continue the process.

Let's proceed to step 9:
2970 divided by 434 is 6 with a remainder of 366.
Use 6 as the next digit of our solution. 
Result so far: 210478.6
Subtracting 2604 from 2970 leaves us with 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Going ahead to step 10:
When dividing 3660 by 434, we get 8 with a remainder of 188.
Write down 8 as next digit of the result. 
Result so far: 210478.68
Subtract 3472 from 3660 to get 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Advancing to step 11:
434 goes into 1880 4 times with a remainder of 144.
The number 4 becomes the next digit in our result. 
Result so far: 210478.684
Deduct 1736 from 1880 and we're left with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Moving on to step 12:
434 can be fit into 1440 3 times, resulting in a remainder of 138.
Record the quotient 3 as the next digit in the result. 
Result so far: 210478.6843
If we take 1302 away from 1440, we end up with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Going ahead to step 13:
434 can be fit into 1380 3 times, resulting in a remainder of 78.
Put 3 as the next digit of the answer. 
Result so far: 210478.68433
Subtract 1302 from 1380 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

In conclusion, the division gives 210478.68433 with a balance of 7.8e-05.
