Let's divide 78137122 by 972
The aim is to understand the frequency of 972 in 78137122.

Moving on to step 1:
If we divide 7 by 972, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 972

Advancing to step 2:
The number 972 fits into 78 0 times, leaving a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Append the next digit (1) from the dividend to 78 and continue with: 781 / 972

On to step 3:
972 goes into 781 0 times with a remainder of 781.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 781, we end up with 781.
Fetch the next digit (3) from the dividend, attach it to 781 and continue: 7813 / 972

Moving on to step 4:
972 can be fit into 7813 8 times, resulting in a remainder of 37.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we subtract 7776 from 7813, we get 37.
Append the next digit (7) from the dividend to 37 and continue with: 377 / 972

Advancing to step 5:
972 goes into 377 0 times with a remainder of 377.
The number 0 becomes the next digit in our result. 
Result so far: 80.0
Deduct 0 from 377 and we're left with 377.
Grab the next digit (1) from the dividend, add it to 377, then carry on: 3771 / 972

Moving on to step 6:
If we divide 3771 by 972, we get 3 and a remainder of 855.
Use 3 as the next digit of our solution. 
Result so far: 803.0
If we take 2916 away from 3771, we end up with 855.
Grab the next digit (2) from the dividend, add it to 855, then carry on: 8552 / 972

Advancing to step 7:
When dividing 8552 by 972, we get 8 with a remainder of 776.
Write down 8 as next digit of the result. 
Result so far: 8038.0
Subtract 7776 from 8552 to get 776.
Append the next digit (2) from the dividend to 776 and continue with: 7762 / 972

Going ahead to step 8:
The number 972 fits into 7762 7 times, leaving a remainder of 958.
Put 7 as the next digit of the answer. 
Result so far: 80387.0
If we take 6804 away from 7762, we end up with 958.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9580, and continue the process.

Advancing to step 9:
972 can be fit into 9580 9 times, resulting in a remainder of 832.
Put 9 as the next digit of the answer. 
Result so far: 80387.9
If we subtract 8748 from 9580, we get 832.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8320, and continue the process.

Going ahead to step 10:
8320 divided by 972 is 8 with a remainder of 544.
The number 8 becomes the next digit in our result. 
Result so far: 80387.98
Deduct 7776 from 8320 and we're left with 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Going ahead to step 11:
972 goes into 5440 5 times with a remainder of 580.
Put 5 as the next digit of the answer. 
Result so far: 80387.985
If we subtract 4860 from 5440, we get 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Let's proceed to step 12:
5800 divided by 972 is 5 with a remainder of 940.
Record the quotient 5 as the next digit in the result. 
Result so far: 80387.9855
Deduct 4860 from 5800 and we're left with 940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9400, and continue the process.

After the division, we end up with 80387.9855 and a remainder of 0.0094.
