70451511 ÷ 415 
We want to figure out the number of times 70451511 can be divided by 415.

On to step 1:
7 divided by 415 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 415

On to step 2:
The number 415 fits into 70 0 times, leaving a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 70 leaves us with 70.
Append the next digit (4) from the dividend to 70 and continue with: 704 / 415

Advancing to step 3:
415 goes into 704 1 times with a remainder of 289.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 415 from 704, we get 289.
Append the next digit (5) from the dividend to 289 and continue with: 2895 / 415

Let's proceed to step 4:
When dividing 2895 by 415, we get 6 with a remainder of 405.
The next digit of our result is 6. 
Result so far: 16.0
Deduct 2490 from 2895 and we're left with 405.
Grab the next digit (1) from the dividend, add it to 405, then carry on: 4051 / 415

Moving on to step 5:
When dividing 4051 by 415, we get 9 with a remainder of 316.
Put 9 as the next digit of the answer. 
Result so far: 169.0
If we take 3735 away from 4051, we end up with 316.
Fetch the next digit (5) from the dividend, attach it to 316 and continue: 3165 / 415

Let's proceed to step 6:
415 goes into 3165 7 times with a remainder of 260.
The next digit of our result is 7. 
Result so far: 1697.0
Subtracting 2905 from 3165 leaves us with 260.
Fetch the next digit (1) from the dividend, attach it to 260 and continue: 2601 / 415

Let's proceed to step 7:
When dividing 2601 by 415, we get 6 with a remainder of 111.
Put 6 as the next digit of the answer. 
Result so far: 16976.0
Deduct 2490 from 2601 and we're left with 111.
Append the next digit (1) from the dividend to 111 and continue with: 1111 / 415

Going ahead to step 8:
415 can be fit into 1111 2 times, resulting in a remainder of 281.
Use 2 as the next digit of our solution. 
Result so far: 169762.0
If we subtract 830 from 1111, we get 281.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2810, and continue the process.

Advancing to step 9:
If we divide 2810 by 415, we get 6 and a remainder of 320.
The number 6 becomes the next digit in our result. 
Result so far: 169762.6
Deduct 2490 from 2810 and we're left with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Moving on to step 10:
If we divide 3200 by 415, we get 7 and a remainder of 295.
Use 7 as the next digit of our solution. 
Result so far: 169762.67
The remainder is 295 after subtracting 2905 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Step 11:
415 can be fit into 2950 7 times, resulting in a remainder of 45.
The number 7 becomes the next digit in our result. 
Result so far: 169762.677
If we subtract 2905 from 2950, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

The final result is 169762.677 with a remainder of 0.0045.
