We divide 55120347 by 15
Our goal is to divide 55120347 by 15.

On to step 1:
15 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 15

Moving on to step 2:
15 can be fit into 55 3 times, resulting in a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 45 from 55, we get 10.
Bring next digit (1) of the dividend behind the 10 and repeat the process: 101 / 15

On to step 3:
15 goes into 101 6 times with a remainder of 11.
The next digit of our result is 6. 
Result so far: 36.0
Deduct 90 from 101 and we're left with 11.
Append the next digit (2) from the dividend to 11 and continue with: 112 / 15

On to step 4:
When dividing 112 by 15, we get 7 with a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 367.0
The remainder is 7 after subtracting 105 from 112.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 15

Moving on to step 5:
15 can be fit into 70 4 times, resulting in a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 3674.0
The remainder is 10 after subtracting 60 from 70.
Take the next digit (3) from the dividend and append it to 10, then repeat: 103 / 15

Step 6:
If we divide 103 by 15, we get 6 and a remainder of 13.
The number 6 becomes the next digit in our result. 
Result so far: 36746.0
If we take 90 away from 103, we end up with 13.
Grab the next digit (4) from the dividend, add it to 13, then carry on: 134 / 15

Advancing to step 7:
If we divide 134 by 15, we get 8 and a remainder of 14.
The number 8 becomes the next digit in our result. 
Result so far: 367468.0
Subtracting 120 from 134 leaves us with 14.
Fetch the next digit (7) from the dividend, attach it to 14 and continue: 147 / 15

On to step 8:
If we divide 147 by 15, we get 9 and a remainder of 12.
Record the quotient 9 as the next digit in the result. 
Result so far: 3674689.0
If we subtract 135 from 147, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 9:
When dividing 120 by 15, we get 8 with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 3674689.8
Subtract 120 from 120 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 10:
The number 15 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 3674689.8
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 11:
When dividing 0 by 15, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 3674689.8
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 3674689.8, and the remainder is 0.0.
