Let's divide 70219248 by 521
We want to figure out the number of times 70219248 can be divided by 521.

Going ahead to step 1:
521 can be fit into 7 0 times, resulting in 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.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 521

Step 2:
521 goes into 70 0 times with a remainder of 70.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 70 after subtracting 0 from 70.
Append the next digit (2) from the dividend to 70 and continue with: 702 / 521

Step 3:
If we divide 702 by 521, we get 1 and a remainder of 181.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 521 from 702 leaves us with 181.
Grab the next digit (1) from the dividend, add it to 181, then carry on: 1811 / 521

On to step 4:
521 can be fit into 1811 3 times, resulting in a remainder of 248.
The next digit of our result is 3. 
Result so far: 13.0
Deduct 1563 from 1811 and we're left with 248.
Bring next digit (9) of the dividend behind the 248 and repeat the process: 2489 / 521

Moving on to step 5:
521 goes into 2489 4 times with a remainder of 405.
Record the quotient 4 as the next digit in the result. 
Result so far: 134.0
Subtracting 2084 from 2489 leaves us with 405.
Grab the next digit (2) from the dividend, add it to 405, then carry on: 4052 / 521

On to step 6:
4052 divided by 521 is 7 with a remainder of 405.
Write down 7 as next digit of the result. 
Result so far: 1347.0
Subtracting 3647 from 4052 leaves us with 405.
Append the next digit (4) from the dividend to 405 and continue with: 4054 / 521

Moving on to step 7:
521 can be fit into 4054 7 times, resulting in a remainder of 407.
Use 7 as the next digit of our solution. 
Result so far: 13477.0
If we subtract 3647 from 4054, we get 407.
Fetch the next digit (8) from the dividend, attach it to 407 and continue: 4078 / 521

Let's proceed to step 8:
When dividing 4078 by 521, we get 7 with a remainder of 431.
Use 7 as the next digit of our solution. 
Result so far: 134777.0
Deduct 3647 from 4078 and we're left with 431.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4310, and continue the process.

Advancing to step 9:
The number 521 fits into 4310 8 times, leaving a remainder of 142.
The next digit of our result is 8. 
Result so far: 134777.8
Deduct 4168 from 4310 and we're left with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

On to step 10:
When dividing 1420 by 521, we get 2 with a remainder of 378.
Put 2 as the next digit of the answer. 
Result so far: 134777.82
If we subtract 1042 from 1420, we get 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Step 11:
The number 521 fits into 3780 7 times, leaving a remainder of 133.
The next digit of our result is 7. 
Result so far: 134777.827
Deduct 3647 from 3780 and we're left with 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Let's proceed to step 12:
When dividing 1330 by 521, we get 2 with a remainder of 288.
Use 2 as the next digit of our solution. 
Result so far: 134777.8272
If we subtract 1042 from 1330, we get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Advancing to step 13:
When dividing 2880 by 521, we get 5 with a remainder of 275.
Write down 5 as next digit of the result. 
Result so far: 134777.82725
Subtract 2605 from 2880 to get 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Step 14:
The number 521 fits into 2750 5 times, leaving a remainder of 145.
Write down 5 as next digit of the result. 
Result so far: 134777.827255
If we subtract 2605 from 2750, we get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Our division results in 134777.827255 with a remaining 1.45e-05.
