Let's divide 79503453 by 972
The aim is to understand the frequency of 972 in 79503453.

Advancing to step 1:
972 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 972

Moving on to step 2:
If we divide 79 by 972, we get 0 and a remainder of 79.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 79 after subtracting 0 from 79.
Take the next digit (5) from the dividend and append it to 79, then repeat: 795 / 972

Advancing to step 3:
The number 972 fits into 795 0 times, leaving a remainder of 795.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 795 and we're left with 795.
Bring next digit (0) of the dividend behind the 795 and repeat the process: 7950 / 972

Moving on to step 4:
972 can be fit into 7950 8 times, resulting in a remainder of 174.
The next digit of our result is 8. 
Result so far: 8.0
The remainder is 174 after subtracting 7776 from 7950.
Bring next digit (3) of the dividend behind the 174 and repeat the process: 1743 / 972

Step 5:
The number 972 fits into 1743 1 times, leaving a remainder of 771.
The next digit of our result is 1. 
Result so far: 81.0
If we take 972 away from 1743, we end up with 771.
Bring next digit (4) of the dividend behind the 771 and repeat the process: 7714 / 972

Going ahead to step 6:
972 can be fit into 7714 7 times, resulting in a remainder of 910.
The next digit of our result is 7. 
Result so far: 817.0
Subtract 6804 from 7714 to get 910.
Include the next digit (5) from the dividend after 910, then repeat: 9105 / 972

Going ahead to step 7:
9105 divided by 972 is 9 with a remainder of 357.
Use 9 as the next digit of our solution. 
Result so far: 8179.0
The remainder is 357 after subtracting 8748 from 9105.
Grab the next digit (3) from the dividend, add it to 357, then carry on: 3573 / 972

Advancing to step 8:
If we divide 3573 by 972, we get 3 and a remainder of 657.
Use 3 as the next digit of our solution. 
Result so far: 81793.0
If we take 2916 away from 3573, we end up with 657.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6570, and continue the process.

Step 9:
972 goes into 6570 6 times with a remainder of 738.
Put 6 as the next digit of the answer. 
Result so far: 81793.6
Subtracting 5832 from 6570 leaves us with 738.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7380, and continue the process.

Advancing to step 10:
The number 972 fits into 7380 7 times, leaving a remainder of 576.
Put 7 as the next digit of the answer. 
Result so far: 81793.67
Subtracting 6804 from 7380 leaves us with 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Moving on to step 11:
When dividing 5760 by 972, we get 5 with a remainder of 900.
The number 5 becomes the next digit in our result. 
Result so far: 81793.675
If we take 4860 away from 5760, we end up with 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9000, and continue the process.

Step 12:
When dividing 9000 by 972, we get 9 with a remainder of 252.
Put 9 as the next digit of the answer. 
Result so far: 81793.6759
Subtracting 8748 from 9000 leaves us with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Step 13:
When dividing 2520 by 972, we get 2 with a remainder of 576.
The number 2 becomes the next digit in our result. 
Result so far: 81793.67592
Deduct 1944 from 2520 and we're left with 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Going ahead to step 14:
If we divide 5760 by 972, we get 5 and a remainder of 900.
Put 5 as the next digit of the answer. 
Result so far: 81793.675925
Deduct 4860 from 5760 and we're left with 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9000, and continue the process.

Step 15:
If we divide 9000 by 972, we get 9 and a remainder of 252.
Record the quotient 9 as the next digit in the result. 
Result so far: 81793.6759259
If we take 8748 away from 9000, we end up with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Step 16:
When dividing 2520 by 972, we get 2 with a remainder of 576.
Use 2 as the next digit of our solution. 
Result so far: 81793.67592592
The remainder is 576 after subtracting 1944 from 2520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

The final outcome is 81793.67592592, with a leftover of 5.76e-07.
