We look at the division of 37776069 by 10 
The aim is to understand the frequency of 10 in 37776069.

Going ahead to step 1:
When dividing 3 by 10, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 10

Advancing to step 2:
When dividing 37 by 10, we get 3 with a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 30 from 37 to get 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 10

Moving on to step 3:
If we divide 77 by 10, we get 7 and a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 37.0
Deduct 70 from 77 and we're left with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 10

Going ahead to step 4:
10 can be fit into 77 7 times, resulting in a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 377.0
The remainder is 7 after subtracting 70 from 77.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 10

On to step 5:
When dividing 76 by 10, we get 7 with a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 3777.0
Subtract 70 from 76 to get 6.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 10

Going ahead to step 6:
10 can be fit into 60 6 times, resulting in a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 37776.0
The remainder is 0 after subtracting 60 from 60.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 10

Going ahead to step 7:
10 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 377760.0
If we take 0 away from 6, we end up with 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 10

On to step 8:
69 divided by 10 is 6 with a remainder of 9.
Record the quotient 6 as the next digit in the result. 
Result so far: 3777606.0
If we take 60 away from 69, we end up 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.

On to step 9:
10 can be fit into 90 9 times, resulting in a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 3777606.9
If we subtract 90 from 90, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
10 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 3777606.9
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 11:
10 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 3777606.9
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 3777606.9 and a remainder of 0.0.
