70418270 ÷ 453 
We want to figure out the number of times 70418270 can be divided by 453.

Let's proceed to step 1:
453 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 453

Advancing to step 2:
If we divide 70 by 453, we get 0 and a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 70 to get 70.
Take the next digit (4) from the dividend and append it to 70, then repeat: 704 / 453

Step 3:
453 goes into 704 1 times with a remainder of 251.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 453 from 704 leaves us with 251.
Append the next digit (1) from the dividend to 251 and continue with: 2511 / 453

Advancing to step 4:
If we divide 2511 by 453, we get 5 and a remainder of 246.
Put 5 as the next digit of the answer. 
Result so far: 15.0
If we take 2265 away from 2511, we end up with 246.
Include the next digit (8) from the dividend after 246, then repeat: 2468 / 453

Advancing to step 5:
453 can be fit into 2468 5 times, resulting in a remainder of 203.
Record the quotient 5 as the next digit in the result. 
Result so far: 155.0
The remainder is 203 after subtracting 2265 from 2468.
Include the next digit (2) from the dividend after 203, then repeat: 2032 / 453

Going ahead to step 6:
When dividing 2032 by 453, we get 4 with a remainder of 220.
Use 4 as the next digit of our solution. 
Result so far: 1554.0
If we take 1812 away from 2032, we end up with 220.
Bring next digit (7) of the dividend behind the 220 and repeat the process: 2207 / 453

Moving on to step 7:
2207 divided by 453 is 4 with a remainder of 395.
Write down 4 as next digit of the result. 
Result so far: 15544.0
If we take 1812 away from 2207, we end up with 395.
Take the next digit (0) from the dividend and append it to 395, then repeat: 3950 / 453

Going ahead to step 8:
453 goes into 3950 8 times with a remainder of 326.
Record the quotient 8 as the next digit in the result. 
Result so far: 155448.0
The remainder is 326 after subtracting 3624 from 3950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Moving on to step 9:
453 goes into 3260 7 times with a remainder of 89.
The next digit of our result is 7. 
Result so far: 155448.7
Subtract 3171 from 3260 to get 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Step 10:
If we divide 890 by 453, we get 1 and a remainder of 437.
The number 1 becomes the next digit in our result. 
Result so far: 155448.71
Subtract 453 from 890 to get 437.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4370, and continue the process.

Going ahead to step 11:
When dividing 4370 by 453, we get 9 with a remainder of 293.
The next digit of our result is 9. 
Result so far: 155448.719
Deduct 4077 from 4370 and we're left with 293.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

Step 12:
453 goes into 2930 6 times with a remainder of 212.
Use 6 as the next digit of our solution. 
Result so far: 155448.7196
Subtract 2718 from 2930 to get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Moving on to step 13:
2120 divided by 453 is 4 with a remainder of 308.
The number 4 becomes the next digit in our result. 
Result so far: 155448.71964
Subtracting 1812 from 2120 leaves us with 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Going ahead to step 14:
453 can be fit into 3080 6 times, resulting in a remainder of 362.
Put 6 as the next digit of the answer. 
Result so far: 155448.719646
Deduct 2718 from 3080 and we're left with 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Going ahead to step 15:
When dividing 3620 by 453, we get 7 with a remainder of 449.
Write down 7 as next digit of the result. 
Result so far: 155448.7196467
If we subtract 3171 from 3620, we get 449.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4490, and continue the process.

On to step 16:
4490 divided by 453 is 9 with a remainder of 413.
The number 9 becomes the next digit in our result. 
Result so far: 155448.71964679
Subtract 4077 from 4490 to get 413.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4130, and continue the process.

The final outcome is 155448.71964679, with a leftover of 4.13e-07.
