We're dividing 15217072 by 153 
We want to divide 15217072 by 153.

Advancing to step 1:
The number 153 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 153

Step 2:
If we divide 15 by 153, we get 0 and a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Take the next digit (2) from the dividend and append it to 15, then repeat: 152 / 153

Step 3:
When dividing 152 by 153, we get 0 with a remainder of 152.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 152, we end up with 152.
Take the next digit (1) from the dividend and append it to 152, then repeat: 1521 / 153

On to step 4:
If we divide 1521 by 153, we get 9 and a remainder of 144.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we take 1377 away from 1521, we end up with 144.
Fetch the next digit (7) from the dividend, attach it to 144 and continue: 1447 / 153

Let's proceed to step 5:
1447 divided by 153 is 9 with a remainder of 70.
The number 9 becomes the next digit in our result. 
Result so far: 99.0
Deduct 1377 from 1447 and we're left with 70.
Grab the next digit (0) from the dividend, add it to 70, then carry on: 700 / 153

Step 6:
153 goes into 700 4 times with a remainder of 88.
The number 4 becomes the next digit in our result. 
Result so far: 994.0
If we take 612 away from 700, we end up with 88.
Fetch the next digit (7) from the dividend, attach it to 88 and continue: 887 / 153

On to step 7:
The number 153 fits into 887 5 times, leaving a remainder of 122.
Write down 5 as next digit of the result. 
Result so far: 9945.0
If we subtract 765 from 887, we get 122.
Take the next digit (2) from the dividend and append it to 122, then repeat: 1222 / 153

Moving on to step 8:
153 can be fit into 1222 7 times, resulting in a remainder of 151.
Record the quotient 7 as the next digit in the result. 
Result so far: 99457.0
The remainder is 151 after subtracting 1071 from 1222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Going ahead to step 9:
153 can be fit into 1510 9 times, resulting in a remainder of 133.
Use 9 as the next digit of our solution. 
Result so far: 99457.9
Subtract 1377 from 1510 to get 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

On to step 10:
153 goes into 1330 8 times with a remainder of 106.
Use 8 as the next digit of our solution. 
Result so far: 99457.98
The remainder is 106 after subtracting 1224 from 1330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Advancing to step 11:
The number 153 fits into 1060 6 times, leaving a remainder of 142.
Write down 6 as next digit of the result. 
Result so far: 99457.986
The remainder is 142 after subtracting 918 from 1060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Moving on to step 12:
If we divide 1420 by 153, we get 9 and a remainder of 43.
Write down 9 as next digit of the result. 
Result so far: 99457.9869
Subtracting 1377 from 1420 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 13:
153 can be fit into 430 2 times, resulting in a remainder of 124.
Use 2 as the next digit of our solution. 
Result so far: 99457.98692
Subtract 306 from 430 to get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Going ahead to step 14:
When dividing 1240 by 153, we get 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 99457.986928
Subtracting 1224 from 1240 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 15:
153 can be fit into 160 1 times, resulting in a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 99457.9869281
Deduct 153 from 160 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 16:
When dividing 70 by 153, we get 0 with a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 99457.9869281
The remainder is 70 after subtracting 0 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final outcome is 99457.9869281, with a leftover of 7e-08.
