We divide 51525567 by 398
We're looking to find how many times 398 goes into 51525567.

Moving on to step 1:
If we divide 5 by 398, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 398

Step 2:
The number 398 fits into 51 0 times, leaving a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Include the next digit (5) from the dividend after 51, then repeat: 515 / 398

Step 3:
515 divided by 398 is 1 with a remainder of 117.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 398 from 515, we get 117.
Bring next digit (2) of the dividend behind the 117 and repeat the process: 1172 / 398

Advancing to step 4:
If we divide 1172 by 398, we get 2 and a remainder of 376.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we subtract 796 from 1172, we get 376.
Include the next digit (5) from the dividend after 376, then repeat: 3765 / 398

Advancing to step 5:
398 goes into 3765 9 times with a remainder of 183.
Use 9 as the next digit of our solution. 
Result so far: 129.0
If we take 3582 away from 3765, we end up with 183.
Grab the next digit (5) from the dividend, add it to 183, then carry on: 1835 / 398

Moving on to step 6:
The number 398 fits into 1835 4 times, leaving a remainder of 243.
Record the quotient 4 as the next digit in the result. 
Result so far: 1294.0
If we subtract 1592 from 1835, we get 243.
Append the next digit (6) from the dividend to 243 and continue with: 2436 / 398

Step 7:
398 goes into 2436 6 times with a remainder of 48.
Use 6 as the next digit of our solution. 
Result so far: 12946.0
The remainder is 48 after subtracting 2388 from 2436.
Fetch the next digit (7) from the dividend, attach it to 48 and continue: 487 / 398

On to step 8:
487 divided by 398 is 1 with a remainder of 89.
The next digit of our result is 1. 
Result so far: 129461.0
Subtract 398 from 487 to get 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Let's proceed to step 9:
The number 398 fits into 890 2 times, leaving a remainder of 94.
Record the quotient 2 as the next digit in the result. 
Result so far: 129461.2
If we take 796 away from 890, we end up with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Moving on to step 10:
940 divided by 398 is 2 with a remainder of 144.
Put 2 as the next digit of the answer. 
Result so far: 129461.22
The remainder is 144 after subtracting 796 from 940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Our division results in 129461.22 with a remaining 0.144.
