19640190 ÷ 376 
The aim is to understand the frequency of 376 in 19640190.

Going ahead to step 1:
If we divide 1 by 376, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 376

On to step 2:
19 divided by 376 is 0 with a remainder of 19.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 19 after subtracting 0 from 19.
Append the next digit (6) from the dividend to 19 and continue with: 196 / 376

On to step 3:
376 goes into 196 0 times with a remainder of 196.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 196 leaves us with 196.
Fetch the next digit (4) from the dividend, attach it to 196 and continue: 1964 / 376

Moving on to step 4:
When dividing 1964 by 376, we get 5 with a remainder of 84.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtracting 1880 from 1964 leaves us with 84.
Include the next digit (0) from the dividend after 84, then repeat: 840 / 376

Let's proceed to step 5:
The number 376 fits into 840 2 times, leaving a remainder of 88.
Put 2 as the next digit of the answer. 
Result so far: 52.0
Subtract 752 from 840 to get 88.
Include the next digit (1) from the dividend after 88, then repeat: 881 / 376

Advancing to step 6:
When dividing 881 by 376, we get 2 with a remainder of 129.
The next digit of our result is 2. 
Result so far: 522.0
If we subtract 752 from 881, we get 129.
Grab the next digit (9) from the dividend, add it to 129, then carry on: 1299 / 376

Step 7:
If we divide 1299 by 376, we get 3 and a remainder of 171.
Use 3 as the next digit of our solution. 
Result so far: 5223.0
Deduct 1128 from 1299 and we're left with 171.
Bring next digit (0) of the dividend behind the 171 and repeat the process: 1710 / 376

Moving on to step 8:
When dividing 1710 by 376, we get 4 with a remainder of 206.
The next digit of our result is 4. 
Result so far: 52234.0
Subtracting 1504 from 1710 leaves us with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Moving on to step 9:
The number 376 fits into 2060 5 times, leaving a remainder of 180.
Write down 5 as next digit of the result. 
Result so far: 52234.5
Deduct 1880 from 2060 and we're left with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Let's proceed to step 10:
When dividing 1800 by 376, we get 4 with a remainder of 296.
Use 4 as the next digit of our solution. 
Result so far: 52234.54
Subtracting 1504 from 1800 leaves us with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Going ahead to step 11:
If we divide 2960 by 376, we get 7 and a remainder of 328.
Record the quotient 7 as the next digit in the result. 
Result so far: 52234.547
If we subtract 2632 from 2960, we get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Step 12:
376 can be fit into 3280 8 times, resulting in a remainder of 272.
Write down 8 as next digit of the result. 
Result so far: 52234.5478
Subtract 3008 from 3280 to get 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Advancing to step 13:
The number 376 fits into 2720 7 times, leaving a remainder of 88.
The next digit of our result is 7. 
Result so far: 52234.54787
If we take 2632 away from 2720, we end up with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

On to step 14:
The number 376 fits into 880 2 times, leaving a remainder of 128.
Write down 2 as next digit of the result. 
Result so far: 52234.547872
Deduct 752 from 880 and we're left with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Advancing to step 15:
The number 376 fits into 1280 3 times, leaving a remainder of 152.
The next digit of our result is 3. 
Result so far: 52234.5478723
Subtracting 1128 from 1280 leaves us with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

On to step 16:
376 goes into 1520 4 times with a remainder of 16.
The next digit of our result is 4. 
Result so far: 52234.54787234
Subtract 1504 from 1520 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 52234.54787234 and a remainder of 1.6e-08.
