We divide 15366999 by 122
We're looking to find how many times 122 goes into 15366999.

Advancing to step 1:
122 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 122

Step 2:
If we divide 15 by 122, we get 0 and a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Include the next digit (3) from the dividend after 15, then repeat: 153 / 122

Advancing to step 3:
The number 122 fits into 153 1 times, leaving a remainder of 31.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 122 from 153 and we're left with 31.
Take the next digit (6) from the dividend and append it to 31, then repeat: 316 / 122

Moving on to step 4:
122 can be fit into 316 2 times, resulting in a remainder of 72.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Deduct 244 from 316 and we're left with 72.
Grab the next digit (6) from the dividend, add it to 72, then carry on: 726 / 122

Going ahead to step 5:
726 divided by 122 is 5 with a remainder of 116.
Use 5 as the next digit of our solution. 
Result so far: 125.0
Subtracting 610 from 726 leaves us with 116.
Include the next digit (9) from the dividend after 116, then repeat: 1169 / 122

Let's proceed to step 6:
The number 122 fits into 1169 9 times, leaving a remainder of 71.
The number 9 becomes the next digit in our result. 
Result so far: 1259.0
The remainder is 71 after subtracting 1098 from 1169.
Take the next digit (9) from the dividend and append it to 71, then repeat: 719 / 122

On to step 7:
122 goes into 719 5 times with a remainder of 109.
Put 5 as the next digit of the answer. 
Result so far: 12595.0
The remainder is 109 after subtracting 610 from 719.
Take the next digit (9) from the dividend and append it to 109, then repeat: 1099 / 122

On to step 8:
1099 divided by 122 is 9 with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 125959.0
Subtracting 1098 from 1099 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 9:
10 divided by 122 is 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 125959.0
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 10:
122 can be fit into 100 0 times, resulting in a remainder of 100.
Write down 0 as next digit of the result. 
Result so far: 125959.0
Deduct 0 from 100 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

After the division, we end up with 125959.0 and a remainder of 0.1.
