We look at the division of 61503538 by 948 
The aim is to understand the frequency of 948 in 61503538.

On to step 1:
6 divided by 948 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 948

Moving on to step 2:
When dividing 61 by 948, we get 0 with a remainder of 61.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 61, we end up with 61.
Append the next digit (5) from the dividend to 61 and continue with: 615 / 948

Moving on to step 3:
948 can be fit into 615 0 times, resulting in a remainder of 615.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 615 leaves us with 615.
Include the next digit (0) from the dividend after 615, then repeat: 6150 / 948

Moving on to step 4:
When dividing 6150 by 948, we get 6 with a remainder of 462.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we take 5688 away from 6150, we end up with 462.
Grab the next digit (3) from the dividend, add it to 462, then carry on: 4623 / 948

Let's proceed to step 5:
The number 948 fits into 4623 4 times, leaving a remainder of 831.
Record the quotient 4 as the next digit in the result. 
Result so far: 64.0
Deduct 3792 from 4623 and we're left with 831.
Fetch the next digit (5) from the dividend, attach it to 831 and continue: 8315 / 948

Going ahead to step 6:
When dividing 8315 by 948, we get 8 with a remainder of 731.
The next digit of our result is 8. 
Result so far: 648.0
If we subtract 7584 from 8315, we get 731.
Include the next digit (3) from the dividend after 731, then repeat: 7313 / 948

On to step 7:
The number 948 fits into 7313 7 times, leaving a remainder of 677.
Record the quotient 7 as the next digit in the result. 
Result so far: 6487.0
Subtracting 6636 from 7313 leaves us with 677.
Take the next digit (8) from the dividend and append it to 677, then repeat: 6778 / 948

On to step 8:
The number 948 fits into 6778 7 times, leaving a remainder of 142.
Put 7 as the next digit of the answer. 
Result so far: 64877.0
If we subtract 6636 from 6778, we get 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Advancing to step 9:
948 can be fit into 1420 1 times, resulting in a remainder of 472.
Record the quotient 1 as the next digit in the result. 
Result so far: 64877.1
Subtract 948 from 1420 to get 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Moving on to step 10:
948 goes into 4720 4 times with a remainder of 928.
The next digit of our result is 4. 
Result so far: 64877.14
If we take 3792 away from 4720, we end up with 928.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9280, and continue the process.

Going ahead to step 11:
9280 divided by 948 is 9 with a remainder of 748.
Put 9 as the next digit of the answer. 
Result so far: 64877.149
If we take 8532 away from 9280, we end up with 748.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7480, and continue the process.

Step 12:
When dividing 7480 by 948, we get 7 with a remainder of 844.
Record the quotient 7 as the next digit in the result. 
Result so far: 64877.1497
Deduct 6636 from 7480 and we're left with 844.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8440, and continue the process.

On to step 13:
When dividing 8440 by 948, we get 8 with a remainder of 856.
Put 8 as the next digit of the answer. 
Result so far: 64877.14978
Deduct 7584 from 8440 and we're left with 856.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8560, and continue the process.

Moving on to step 14:
948 goes into 8560 9 times with a remainder of 28.
Write down 9 as next digit of the result. 
Result so far: 64877.149789
If we take 8532 away from 8560, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 15:
948 goes into 280 0 times with a remainder of 280.
The number 0 becomes the next digit in our result. 
Result so far: 64877.149789
Subtracting 0 from 280 leaves us with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Let's proceed to step 16:
2800 divided by 948 is 2 with a remainder of 904.
Write down 2 as next digit of the result. 
Result so far: 64877.14978902
Deduct 1896 from 2800 and we're left with 904.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9040, and continue the process.

After the division, we end up with 64877.14978902 and a remainder of 9.04e-07.
