We look at the division of 70784419 by 453 
We want to figure out the number of times 70784419 can be divided by 453.

Going ahead to step 1:
When dividing 7 by 453, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 453

Moving on to step 2:
If we divide 70 by 453, we get 0 and a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 70 after subtracting 0 from 70.
Append the next digit (7) from the dividend to 70 and continue with: 707 / 453

Step 3:
If we divide 707 by 453, we get 1 and a remainder of 254.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 453 from 707 to get 254.
Fetch the next digit (8) from the dividend, attach it to 254 and continue: 2548 / 453

Going ahead to step 4:
453 can be fit into 2548 5 times, resulting in a remainder of 283.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
The remainder is 283 after subtracting 2265 from 2548.
Grab the next digit (4) from the dividend, add it to 283, then carry on: 2834 / 453

Going ahead to step 5:
When dividing 2834 by 453, we get 6 with a remainder of 116.
Write down 6 as next digit of the result. 
Result so far: 156.0
Subtract 2718 from 2834 to get 116.
Bring next digit (4) of the dividend behind the 116 and repeat the process: 1164 / 453

Advancing to step 6:
The number 453 fits into 1164 2 times, leaving a remainder of 258.
Use 2 as the next digit of our solution. 
Result so far: 1562.0
Subtracting 906 from 1164 leaves us with 258.
Grab the next digit (1) from the dividend, add it to 258, then carry on: 2581 / 453

Step 7:
If we divide 2581 by 453, we get 5 and a remainder of 316.
The number 5 becomes the next digit in our result. 
Result so far: 15625.0
If we subtract 2265 from 2581, we get 316.
Grab the next digit (9) from the dividend, add it to 316, then carry on: 3169 / 453

Moving on to step 8:
If we divide 3169 by 453, we get 6 and a remainder of 451.
The number 6 becomes the next digit in our result. 
Result so far: 156256.0
Subtract 2718 from 3169 to get 451.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4510, and continue the process.

Moving on to step 9:
4510 divided by 453 is 9 with a remainder of 433.
Put 9 as the next digit of the answer. 
Result so far: 156256.9
Subtract 4077 from 4510 to get 433.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4330, and continue the process.

Advancing to step 10:
453 goes into 4330 9 times with a remainder of 253.
Put 9 as the next digit of the answer. 
Result so far: 156256.99
Deduct 4077 from 4330 and we're left with 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

After the division, we end up with 156256.99 and a remainder of 0.253.
