We divide 11987171 by 376
The aim is to understand the frequency of 376 in 11987171.

On to step 1:
1 divided by 376 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 376

On to step 2:
376 can be fit into 11 0 times, resulting in a remainder of 11.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 11, we end up with 11.
Append the next digit (9) from the dividend to 11 and continue with: 119 / 376

Advancing to step 3:
119 divided by 376 is 0 with a remainder of 119.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 119 and we're left with 119.
Append the next digit (8) from the dividend to 119 and continue with: 1198 / 376

Going ahead to step 4:
376 goes into 1198 3 times with a remainder of 70.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 1128 from 1198 and we're left with 70.
Bring next digit (7) of the dividend behind the 70 and repeat the process: 707 / 376

Advancing to step 5:
When dividing 707 by 376, we get 1 with a remainder of 331.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
Subtracting 376 from 707 leaves us with 331.
Append the next digit (1) from the dividend to 331 and continue with: 3311 / 376

Advancing to step 6:
If we divide 3311 by 376, we get 8 and a remainder of 303.
Put 8 as the next digit of the answer. 
Result so far: 318.0
Subtracting 3008 from 3311 leaves us with 303.
Fetch the next digit (7) from the dividend, attach it to 303 and continue: 3037 / 376

Going ahead to step 7:
376 goes into 3037 8 times with a remainder of 29.
Record the quotient 8 as the next digit in the result. 
Result so far: 3188.0
Deduct 3008 from 3037 and we're left with 29.
Append the next digit (1) from the dividend to 29 and continue with: 291 / 376

On to step 8:
376 goes into 291 0 times with a remainder of 291.
Write down 0 as next digit of the result. 
Result so far: 31880.0
Subtract 0 from 291 to get 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

Let's proceed to step 9:
The number 376 fits into 2910 7 times, leaving a remainder of 278.
Use 7 as the next digit of our solution. 
Result so far: 31880.7
If we subtract 2632 from 2910, we get 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

On to step 10:
If we divide 2780 by 376, we get 7 and a remainder of 148.
Record the quotient 7 as the next digit in the result. 
Result so far: 31880.77
Subtract 2632 from 2780 to get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

The quotient of the division is 31880.77, and the remainder is 0.148.
