15239109 ÷ 972 
We want to divide 15239109 by 972.

Advancing to step 1:
972 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 972

On to step 2:
If we divide 15 by 972, 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 / 972

Moving on to step 3:
When dividing 152 by 972, we get 0 with a remainder of 152.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 152, we get 152.
Include the next digit (3) from the dividend after 152, then repeat: 1523 / 972

Advancing to step 4:
If we divide 1523 by 972, we get 1 and a remainder of 551.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 972 from 1523 to get 551.
Take the next digit (9) from the dividend and append it to 551, then repeat: 5519 / 972

Step 5:
When dividing 5519 by 972, we get 5 with a remainder of 659.
Write down 5 as next digit of the result. 
Result so far: 15.0
Deduct 4860 from 5519 and we're left with 659.
Fetch the next digit (1) from the dividend, attach it to 659 and continue: 6591 / 972

Step 6:
When dividing 6591 by 972, we get 6 with a remainder of 759.
Put 6 as the next digit of the answer. 
Result so far: 156.0
Deduct 5832 from 6591 and we're left with 759.
Bring next digit (0) of the dividend behind the 759 and repeat the process: 7590 / 972

Step 7:
972 can be fit into 7590 7 times, resulting in a remainder of 786.
Record the quotient 7 as the next digit in the result. 
Result so far: 1567.0
If we take 6804 away from 7590, we end up with 786.
Append the next digit (9) from the dividend to 786 and continue with: 7869 / 972

Advancing to step 8:
972 goes into 7869 8 times with a remainder of 93.
The number 8 becomes the next digit in our result. 
Result so far: 15678.0
Subtract 7776 from 7869 to get 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Step 9:
972 can be fit into 930 0 times, resulting in a remainder of 930.
Use 0 as the next digit of our solution. 
Result so far: 15678.0
If we take 0 away from 930, we end up with 930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9300, and continue the process.

Advancing to step 10:
9300 divided by 972 is 9 with a remainder of 552.
Record the quotient 9 as the next digit in the result. 
Result so far: 15678.09
The remainder is 552 after subtracting 8748 from 9300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

Advancing to step 11:
972 can be fit into 5520 5 times, resulting in a remainder of 660.
The number 5 becomes the next digit in our result. 
Result so far: 15678.095
The remainder is 660 after subtracting 4860 from 5520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Advancing to step 12:
972 goes into 6600 6 times with a remainder of 768.
Record the quotient 6 as the next digit in the result. 
Result so far: 15678.0956
Deduct 5832 from 6600 and we're left with 768.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7680, and continue the process.

On to step 13:
The number 972 fits into 7680 7 times, leaving a remainder of 876.
Write down 7 as next digit of the result. 
Result so far: 15678.09567
Subtracting 6804 from 7680 leaves us with 876.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8760, and continue the process.

Let's proceed to step 14:
972 goes into 8760 9 times with a remainder of 12.
Write down 9 as next digit of the result. 
Result so far: 15678.095679
Deduct 8748 from 8760 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 15:
972 can be fit into 120 0 times, resulting in a remainder of 120.
Put 0 as the next digit of the answer. 
Result so far: 15678.095679
If we take 0 away from 120, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 16:
1200 divided by 972 is 1 with a remainder of 228.
Put 1 as the next digit of the answer. 
Result so far: 15678.09567901
If we take 972 away from 1200, we end up with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

After the division, we end up with 15678.09567901 and a remainder of 2.28e-07.
