We look at the division of 70480376 by 521 
We want to divide 70480376 by 521.

Step 1:
When dividing 7 by 521, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 521

On to step 2:
The number 521 fits into 70 0 times, leaving a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 70, we get 70.
Fetch the next digit (4) from the dividend, attach it to 70 and continue: 704 / 521

Step 3:
521 goes into 704 1 times with a remainder of 183.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 183 after subtracting 521 from 704.
Include the next digit (8) from the dividend after 183, then repeat: 1838 / 521

Advancing to step 4:
521 can be fit into 1838 3 times, resulting in a remainder of 275.
The next digit of our result is 3. 
Result so far: 13.0
If we subtract 1563 from 1838, we get 275.
Bring next digit (0) of the dividend behind the 275 and repeat the process: 2750 / 521

Going ahead to step 5:
When dividing 2750 by 521, we get 5 with a remainder of 145.
Use 5 as the next digit of our solution. 
Result so far: 135.0
If we take 2605 away from 2750, we end up with 145.
Grab the next digit (3) from the dividend, add it to 145, then carry on: 1453 / 521

Let's proceed to step 6:
1453 divided by 521 is 2 with a remainder of 411.
Record the quotient 2 as the next digit in the result. 
Result so far: 1352.0
The remainder is 411 after subtracting 1042 from 1453.
Take the next digit (7) from the dividend and append it to 411, then repeat: 4117 / 521

Let's proceed to step 7:
The number 521 fits into 4117 7 times, leaving a remainder of 470.
Write down 7 as next digit of the result. 
Result so far: 13527.0
Subtract 3647 from 4117 to get 470.
Fetch the next digit (6) from the dividend, attach it to 470 and continue: 4706 / 521

Moving on to step 8:
521 goes into 4706 9 times with a remainder of 17.
The next digit of our result is 9. 
Result so far: 135279.0
If we take 4689 away from 4706, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 9:
The number 521 fits into 170 0 times, leaving a remainder of 170.
The number 0 becomes the next digit in our result. 
Result so far: 135279.0
If we subtract 0 from 170, we get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Advancing to step 10:
521 goes into 1700 3 times with a remainder of 137.
Write down 3 as next digit of the result. 
Result so far: 135279.03
Subtract 1563 from 1700 to get 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Going ahead to step 11:
521 goes into 1370 2 times with a remainder of 328.
Use 2 as the next digit of our solution. 
Result so far: 135279.032
If we take 1042 away from 1370, we end up with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Moving on to step 12:
521 goes into 3280 6 times with a remainder of 154.
The number 6 becomes the next digit in our result. 
Result so far: 135279.0326
The remainder is 154 after subtracting 3126 from 3280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Let's proceed to step 13:
When dividing 1540 by 521, we get 2 with a remainder of 498.
The number 2 becomes the next digit in our result. 
Result so far: 135279.03262
If we take 1042 away from 1540, we end up with 498.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4980, and continue the process.

Let's proceed to step 14:
4980 divided by 521 is 9 with a remainder of 291.
Use 9 as the next digit of our solution. 
Result so far: 135279.032629
If we take 4689 away from 4980, we end up with 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

Step 15:
The number 521 fits into 2910 5 times, leaving a remainder of 305.
The next digit of our result is 5. 
Result so far: 135279.0326295
The remainder is 305 after subtracting 2605 from 2910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Going ahead to step 16:
If we divide 3050 by 521, we get 5 and a remainder of 445.
The next digit of our result is 5. 
Result so far: 135279.03262955
Deduct 2605 from 3050 and we're left with 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

The final outcome is 135279.03262955, with a leftover of 4.45e-07.
