72090515 divided by 972 
The aim is to understand the frequency of 972 in 72090515.

Step 1:
972 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 972

Step 2:
972 can be fit into 72 0 times, resulting in a remainder of 72.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 72, we get 72.
Include the next digit (0) from the dividend after 72, then repeat: 720 / 972

Moving on to step 3:
The number 972 fits into 720 0 times, leaving a remainder of 720.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 720 to get 720.
Include the next digit (9) from the dividend after 720, then repeat: 7209 / 972

Step 4:
972 goes into 7209 7 times with a remainder of 405.
The next digit of our result is 7. 
Result so far: 7.0
If we take 6804 away from 7209, we end up with 405.
Include the next digit (0) from the dividend after 405, then repeat: 4050 / 972

Advancing to step 5:
972 goes into 4050 4 times with a remainder of 162.
Use 4 as the next digit of our solution. 
Result so far: 74.0
Subtract 3888 from 4050 to get 162.
Bring next digit (5) of the dividend behind the 162 and repeat the process: 1625 / 972

On to step 6:
The number 972 fits into 1625 1 times, leaving a remainder of 653.
Use 1 as the next digit of our solution. 
Result so far: 741.0
Subtracting 972 from 1625 leaves us with 653.
Append the next digit (1) from the dividend to 653 and continue with: 6531 / 972

Let's proceed to step 7:
The number 972 fits into 6531 6 times, leaving a remainder of 699.
Write down 6 as next digit of the result. 
Result so far: 7416.0
Deduct 5832 from 6531 and we're left with 699.
Append the next digit (5) from the dividend to 699 and continue with: 6995 / 972

Moving on to step 8:
If we divide 6995 by 972, we get 7 and a remainder of 191.
Put 7 as the next digit of the answer. 
Result so far: 74167.0
Subtracting 6804 from 6995 leaves us with 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

Moving on to step 9:
972 goes into 1910 1 times with a remainder of 938.
Put 1 as the next digit of the answer. 
Result so far: 74167.1
Subtract 972 from 1910 to get 938.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9380, and continue the process.

Going ahead to step 10:
When dividing 9380 by 972, we get 9 with a remainder of 632.
Record the quotient 9 as the next digit in the result. 
Result so far: 74167.19
Deduct 8748 from 9380 and we're left with 632.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

Let's proceed to step 11:
When dividing 6320 by 972, we get 6 with a remainder of 488.
Use 6 as the next digit of our solution. 
Result so far: 74167.196
Deduct 5832 from 6320 and we're left with 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

On to step 12:
When dividing 4880 by 972, we get 5 with a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 74167.1965
Subtract 4860 from 4880 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 13:
The number 972 fits into 200 0 times, leaving a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 74167.1965
Subtracting 0 from 200 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 14:
972 can be fit into 2000 2 times, resulting in a remainder of 56.
Write down 2 as next digit of the result. 
Result so far: 74167.196502
Deduct 1944 from 2000 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 15:
560 divided by 972 is 0 with a remainder of 560.
Put 0 as the next digit of the answer. 
Result so far: 74167.196502
If we take 0 away from 560, we end up with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Going ahead to step 16:
5600 divided by 972 is 5 with a remainder of 740.
The number 5 becomes the next digit in our result. 
Result so far: 74167.19650205
Subtracting 4860 from 5600 leaves us with 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

Our division results in 74167.19650205 with a remaining 7.4e-07.
