45249459 ÷ 612 
We want to divide 45249459 by 612.

Moving on to step 1:
If we divide 4 by 612, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 612

Advancing to step 2:
45 divided by 612 is 0 with a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 45 and we're left with 45.
Take the next digit (2) from the dividend and append it to 45, then repeat: 452 / 612

Step 3:
612 goes into 452 0 times with a remainder of 452.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 452 after subtracting 0 from 452.
Bring next digit (4) of the dividend behind the 452 and repeat the process: 4524 / 612

Going ahead to step 4:
The number 612 fits into 4524 7 times, leaving a remainder of 240.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we subtract 4284 from 4524, we get 240.
Include the next digit (9) from the dividend after 240, then repeat: 2409 / 612

Going ahead to step 5:
When dividing 2409 by 612, we get 3 with a remainder of 573.
Put 3 as the next digit of the answer. 
Result so far: 73.0
The remainder is 573 after subtracting 1836 from 2409.
Include the next digit (4) from the dividend after 573, then repeat: 5734 / 612

On to step 6:
612 can be fit into 5734 9 times, resulting in a remainder of 226.
The number 9 becomes the next digit in our result. 
Result so far: 739.0
The remainder is 226 after subtracting 5508 from 5734.
Append the next digit (5) from the dividend to 226 and continue with: 2265 / 612

Let's proceed to step 7:
When dividing 2265 by 612, we get 3 with a remainder of 429.
The next digit of our result is 3. 
Result so far: 7393.0
Deduct 1836 from 2265 and we're left with 429.
Take the next digit (9) from the dividend and append it to 429, then repeat: 4299 / 612

Moving on to step 8:
612 can be fit into 4299 7 times, resulting in a remainder of 15.
The next digit of our result is 7. 
Result so far: 73937.0
Deduct 4284 from 4299 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 9:
612 can be fit into 150 0 times, resulting in a remainder of 150.
Put 0 as the next digit of the answer. 
Result so far: 73937.0
The remainder is 150 after subtracting 0 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 10:
1500 divided by 612 is 2 with a remainder of 276.
The next digit of our result is 2. 
Result so far: 73937.02
If we take 1224 away from 1500, we end up with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Step 11:
612 can be fit into 2760 4 times, resulting in a remainder of 312.
Write down 4 as next digit of the result. 
Result so far: 73937.024
Subtracting 2448 from 2760 leaves us with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Let's proceed to step 12:
612 can be fit into 3120 5 times, resulting in a remainder of 60.
The next digit of our result is 5. 
Result so far: 73937.0245
Subtracting 3060 from 3120 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 13:
612 can be fit into 600 0 times, resulting in a remainder of 600.
Record the quotient 0 as the next digit in the result. 
Result so far: 73937.0245
Subtract 0 from 600 to get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

On to step 14:
The number 612 fits into 6000 9 times, leaving a remainder of 492.
Put 9 as the next digit of the answer. 
Result so far: 73937.024509
If we subtract 5508 from 6000, we get 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

Step 15:
4920 divided by 612 is 8 with a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 73937.0245098
The remainder is 24 after subtracting 4896 from 4920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 16:
612 goes into 240 0 times with a remainder of 240.
Use 0 as the next digit of our solution. 
Result so far: 73937.0245098
Deduct 0 from 240 and we're left with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Our division results in 73937.0245098 with a remaining 2.4e-07.
