We look at the division of 50712145 by 931 
The aim is to understand the frequency of 931 in 50712145.

Step 1:
931 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 931

Let's proceed to step 2:
50 divided by 931 is 0 with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 50 to get 50.
Append the next digit (7) from the dividend to 50 and continue with: 507 / 931

Advancing to step 3:
If we divide 507 by 931, we get 0 and a remainder of 507.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 507 to get 507.
Take the next digit (1) from the dividend and append it to 507, then repeat: 5071 / 931

Advancing to step 4:
When dividing 5071 by 931, we get 5 with a remainder of 416.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Deduct 4655 from 5071 and we're left with 416.
Take the next digit (2) from the dividend and append it to 416, then repeat: 4162 / 931

Advancing to step 5:
931 goes into 4162 4 times with a remainder of 438.
Write down 4 as next digit of the result. 
Result so far: 54.0
Deduct 3724 from 4162 and we're left with 438.
Fetch the next digit (1) from the dividend, attach it to 438 and continue: 4381 / 931

On to step 6:
931 can be fit into 4381 4 times, resulting in a remainder of 657.
Put 4 as the next digit of the answer. 
Result so far: 544.0
Subtracting 3724 from 4381 leaves us with 657.
Grab the next digit (4) from the dividend, add it to 657, then carry on: 6574 / 931

Step 7:
The number 931 fits into 6574 7 times, leaving a remainder of 57.
Use 7 as the next digit of our solution. 
Result so far: 5447.0
Subtracting 6517 from 6574 leaves us with 57.
Take the next digit (5) from the dividend and append it to 57, then repeat: 575 / 931

Moving on to step 8:
When dividing 575 by 931, we get 0 with a remainder of 575.
The next digit of our result is 0. 
Result so far: 54470.0
If we subtract 0 from 575, we get 575.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5750, and continue the process.

Moving on to step 9:
5750 divided by 931 is 6 with a remainder of 164.
The number 6 becomes the next digit in our result. 
Result so far: 54470.6
If we subtract 5586 from 5750, we get 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Let's proceed to step 10:
If we divide 1640 by 931, we get 1 and a remainder of 709.
The number 1 becomes the next digit in our result. 
Result so far: 54470.61
If we take 931 away from 1640, we end up with 709.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7090, and continue the process.

Step 11:
931 can be fit into 7090 7 times, resulting in a remainder of 573.
The next digit of our result is 7. 
Result so far: 54470.617
If we subtract 6517 from 7090, we get 573.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5730, and continue the process.

Let's proceed to step 12:
931 goes into 5730 6 times with a remainder of 144.
The next digit of our result is 6. 
Result so far: 54470.6176
Subtract 5586 from 5730 to get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

On to step 13:
931 goes into 1440 1 times with a remainder of 509.
The next digit of our result is 1. 
Result so far: 54470.61761
Deduct 931 from 1440 and we're left with 509.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5090, and continue the process.

Let's proceed to step 14:
If we divide 5090 by 931, we get 5 and a remainder of 435.
The next digit of our result is 5. 
Result so far: 54470.617615
The remainder is 435 after subtracting 4655 from 5090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4350, and continue the process.

On to step 15:
4350 divided by 931 is 4 with a remainder of 626.
Use 4 as the next digit of our solution. 
Result so far: 54470.6176154
Subtracting 3724 from 4350 leaves us with 626.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6260, and continue the process.

Step 16:
931 can be fit into 6260 6 times, resulting in a remainder of 674.
Record the quotient 6 as the next digit in the result. 
Result so far: 54470.61761546
If we subtract 5586 from 6260, we get 674.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6740, and continue the process.

The final result is 54470.61761546 with a remainder of 6.74e-07.
