We divide 52215491 by 478
We want to figure out the number of times 52215491 can be divided by 478.

Going ahead to step 1:
The number 478 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 478

Advancing to step 2:
The number 478 fits into 52 0 times, leaving a remainder of 52.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 52, we get 52.
Bring next digit (2) of the dividend behind the 52 and repeat the process: 522 / 478

Moving on to step 3:
522 divided by 478 is 1 with a remainder of 44.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 478 from 522 leaves us with 44.
Grab the next digit (1) from the dividend, add it to 44, then carry on: 441 / 478

Let's proceed to step 4:
If we divide 441 by 478, we get 0 and a remainder of 441.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we subtract 0 from 441, we get 441.
Take the next digit (5) from the dividend and append it to 441, then repeat: 4415 / 478

On to step 5:
If we divide 4415 by 478, we get 9 and a remainder of 113.
Write down 9 as next digit of the result. 
Result so far: 109.0
Subtract 4302 from 4415 to get 113.
Append the next digit (4) from the dividend to 113 and continue with: 1134 / 478

Let's proceed to step 6:
The number 478 fits into 1134 2 times, leaving a remainder of 178.
The number 2 becomes the next digit in our result. 
Result so far: 1092.0
Subtract 956 from 1134 to get 178.
Bring next digit (9) of the dividend behind the 178 and repeat the process: 1789 / 478

Moving on to step 7:
If we divide 1789 by 478, we get 3 and a remainder of 355.
Put 3 as the next digit of the answer. 
Result so far: 10923.0
Subtracting 1434 from 1789 leaves us with 355.
Fetch the next digit (1) from the dividend, attach it to 355 and continue: 3551 / 478

On to step 8:
The number 478 fits into 3551 7 times, leaving a remainder of 205.
The next digit of our result is 7. 
Result so far: 109237.0
Subtracting 3346 from 3551 leaves us with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Step 9:
If we divide 2050 by 478, we get 4 and a remainder of 138.
Record the quotient 4 as the next digit in the result. 
Result so far: 109237.4
If we take 1912 away from 2050, we end up with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Moving on to step 10:
478 goes into 1380 2 times with a remainder of 424.
The number 2 becomes the next digit in our result. 
Result so far: 109237.42
Subtract 956 from 1380 to get 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Going ahead to step 11:
4240 divided by 478 is 8 with a remainder of 416.
The number 8 becomes the next digit in our result. 
Result so far: 109237.428
If we subtract 3824 from 4240, we get 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Step 12:
4160 divided by 478 is 8 with a remainder of 336.
Use 8 as the next digit of our solution. 
Result so far: 109237.4288
If we subtract 3824 from 4160, we get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

The final outcome is 109237.4288, with a leftover of 0.00336.
