45243787 ÷ 434 
We want to divide 45243787 by 434.

Let's proceed to step 1:
434 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 434

Moving on to step 2:
434 goes into 45 0 times with a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 45, we get 45.
Take the next digit (2) from the dividend and append it to 45, then repeat: 452 / 434

Let's proceed to step 3:
If we divide 452 by 434, we get 1 and a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 434 from 452 leaves us with 18.
Append the next digit (4) from the dividend to 18 and continue with: 184 / 434

Moving on to step 4:
If we divide 184 by 434, we get 0 and a remainder of 184.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we subtract 0 from 184, we get 184.
Bring next digit (3) of the dividend behind the 184 and repeat the process: 1843 / 434

Advancing to step 5:
When dividing 1843 by 434, we get 4 with a remainder of 107.
The number 4 becomes the next digit in our result. 
Result so far: 104.0
The remainder is 107 after subtracting 1736 from 1843.
Take the next digit (7) from the dividend and append it to 107, then repeat: 1077 / 434

On to step 6:
434 can be fit into 1077 2 times, resulting in a remainder of 209.
Write down 2 as next digit of the result. 
Result so far: 1042.0
If we take 868 away from 1077, we end up with 209.
Bring next digit (8) of the dividend behind the 209 and repeat the process: 2098 / 434

Step 7:
If we divide 2098 by 434, we get 4 and a remainder of 362.
Write down 4 as next digit of the result. 
Result so far: 10424.0
Subtracting 1736 from 2098 leaves us with 362.
Fetch the next digit (7) from the dividend, attach it to 362 and continue: 3627 / 434

Going ahead to step 8:
434 goes into 3627 8 times with a remainder of 155.
Record the quotient 8 as the next digit in the result. 
Result so far: 104248.0
Subtract 3472 from 3627 to get 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Let's proceed to step 9:
1550 divided by 434 is 3 with a remainder of 248.
The number 3 becomes the next digit in our result. 
Result so far: 104248.3
Subtract 1302 from 1550 to get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Going ahead to step 10:
When dividing 2480 by 434, we get 5 with a remainder of 310.
Put 5 as the next digit of the answer. 
Result so far: 104248.35
Subtract 2170 from 2480 to get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Advancing to step 11:
3100 divided by 434 is 7 with a remainder of 62.
The number 7 becomes the next digit in our result. 
Result so far: 104248.357
If we subtract 3038 from 3100, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 12:
620 divided by 434 is 1 with a remainder of 186.
The number 1 becomes the next digit in our result. 
Result so far: 104248.3571
If we take 434 away from 620, we end up with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Advancing to step 13:
When dividing 1860 by 434, we get 4 with a remainder of 124.
The next digit of our result is 4. 
Result so far: 104248.35714
The remainder is 124 after subtracting 1736 from 1860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Going ahead to step 14:
If we divide 1240 by 434, we get 2 and a remainder of 372.
Use 2 as the next digit of our solution. 
Result so far: 104248.357142
The remainder is 372 after subtracting 868 from 1240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Advancing to step 15:
When dividing 3720 by 434, we get 8 with a remainder of 248.
The number 8 becomes the next digit in our result. 
Result so far: 104248.3571428
Deduct 3472 from 3720 and we're left with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Advancing to step 16:
434 can be fit into 2480 5 times, resulting in a remainder of 310.
Write down 5 as next digit of the result. 
Result so far: 104248.35714285
Deduct 2170 from 2480 and we're left with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

The final result is 104248.35714285 with a remainder of 3.1e-07.
