We're dividing 68428577 by 31 
The aim is to understand the frequency of 31 in 68428577.

Going ahead to step 1:
31 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 31

Let's proceed to step 2:
The number 31 fits into 68 2 times, leaving a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 6 after subtracting 62 from 68.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 31

Step 3:
The number 31 fits into 64 2 times, leaving a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 22.0
If we take 62 away from 64, we end up with 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 31

Going ahead to step 4:
The number 31 fits into 22 0 times, leaving a remainder of 22.
The next digit of our result is 0. 
Result so far: 220.0
If we take 0 away from 22, we end up with 22.
Take the next digit (8) from the dividend and append it to 22, then repeat: 228 / 31

Moving on to step 5:
When dividing 228 by 31, we get 7 with a remainder of 11.
Write down 7 as next digit of the result. 
Result so far: 2207.0
If we subtract 217 from 228, we get 11.
Fetch the next digit (5) from the dividend, attach it to 11 and continue: 115 / 31

Moving on to step 6:
31 goes into 115 3 times with a remainder of 22.
Write down 3 as next digit of the result. 
Result so far: 22073.0
Subtracting 93 from 115 leaves us with 22.
Grab the next digit (7) from the dividend, add it to 22, then carry on: 227 / 31

Advancing to step 7:
31 goes into 227 7 times with a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 220737.0
Subtracting 217 from 227 leaves us with 10.
Append the next digit (7) from the dividend to 10 and continue with: 107 / 31

On to step 8:
The number 31 fits into 107 3 times, leaving a remainder of 14.
The number 3 becomes the next digit in our result. 
Result so far: 2207373.0
Subtract 93 from 107 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 9:
31 can be fit into 140 4 times, resulting in a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 2207373.4
The remainder is 16 after subtracting 124 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 10:
The number 31 fits into 160 5 times, leaving a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 2207373.45
Deduct 155 from 160 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 11:
50 divided by 31 is 1 with a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 2207373.451
If we take 31 away from 50, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 12:
If we divide 190 by 31, we get 6 and a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 2207373.4516
Subtracting 186 from 190 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 13:
When dividing 40 by 31, we get 1 with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 2207373.45161
Deduct 31 from 40 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 14:
When dividing 90 by 31, we get 2 with a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 2207373.451612
Deduct 62 from 90 and we're left 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.

Step 15:
31 can be fit into 280 9 times, resulting in a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 2207373.4516129
If we take 279 away from 280, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 16:
31 goes into 10 0 times with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 2207373.4516129
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The quotient of the division is 2207373.4516129, and the remainder is 1e-08.
