We're dividing 15985037 by 972 
We want to divide 15985037 by 972.

Moving on to step 1:
972 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 972

On to step 2:
The number 972 fits into 15 0 times, leaving a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Fetch the next digit (9) from the dividend, attach it to 15 and continue: 159 / 972

Step 3:
The number 972 fits into 159 0 times, leaving a remainder of 159.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 159 to get 159.
Append the next digit (8) from the dividend to 159 and continue with: 1598 / 972

Going ahead to step 4:
972 goes into 1598 1 times with a remainder of 626.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 972 away from 1598, we end up with 626.
Take the next digit (5) from the dividend and append it to 626, then repeat: 6265 / 972

Step 5:
If we divide 6265 by 972, we get 6 and a remainder of 433.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
Deduct 5832 from 6265 and we're left with 433.
Append the next digit (0) from the dividend to 433 and continue with: 4330 / 972

Let's proceed to step 6:
4330 divided by 972 is 4 with a remainder of 442.
Put 4 as the next digit of the answer. 
Result so far: 164.0
Subtracting 3888 from 4330 leaves us with 442.
Fetch the next digit (3) from the dividend, attach it to 442 and continue: 4423 / 972

Going ahead to step 7:
4423 divided by 972 is 4 with a remainder of 535.
The number 4 becomes the next digit in our result. 
Result so far: 1644.0
The remainder is 535 after subtracting 3888 from 4423.
Fetch the next digit (7) from the dividend, attach it to 535 and continue: 5357 / 972

Moving on to step 8:
972 can be fit into 5357 5 times, resulting in a remainder of 497.
Record the quotient 5 as the next digit in the result. 
Result so far: 16445.0
The remainder is 497 after subtracting 4860 from 5357.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4970, and continue the process.

Step 9:
972 goes into 4970 5 times with a remainder of 110.
Write down 5 as next digit of the result. 
Result so far: 16445.5
The remainder is 110 after subtracting 4860 from 4970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

On to step 10:
When dividing 1100 by 972, we get 1 with a remainder of 128.
Put 1 as the next digit of the answer. 
Result so far: 16445.51
Subtracting 972 from 1100 leaves us with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

On to step 11:
1280 divided by 972 is 1 with a remainder of 308.
Record the quotient 1 as the next digit in the result. 
Result so far: 16445.511
If we take 972 away from 1280, we end up with 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

After the division, we end up with 16445.511 and a remainder of 0.0308.
