We divide 37189996 by 991
The aim is to understand the frequency of 991 in 37189996.

Going ahead to step 1:
The number 991 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 991

Let's proceed to step 2:
If we divide 37 by 991, we get 0 and a remainder of 37.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 37 to get 37.
Include the next digit (1) from the dividend after 37, then repeat: 371 / 991

Let's proceed to step 3:
991 goes into 371 0 times with a remainder of 371.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 371 leaves us with 371.
Grab the next digit (8) from the dividend, add it to 371, then carry on: 3718 / 991

Step 4:
If we divide 3718 by 991, we get 3 and a remainder of 745.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 745 after subtracting 2973 from 3718.
Include the next digit (9) from the dividend after 745, then repeat: 7459 / 991

On to step 5:
When dividing 7459 by 991, we get 7 with a remainder of 522.
Use 7 as the next digit of our solution. 
Result so far: 37.0
If we subtract 6937 from 7459, we get 522.
Append the next digit (9) from the dividend to 522 and continue with: 5229 / 991

Let's proceed to step 6:
991 can be fit into 5229 5 times, resulting in a remainder of 274.
The next digit of our result is 5. 
Result so far: 375.0
The remainder is 274 after subtracting 4955 from 5229.
Append the next digit (9) from the dividend to 274 and continue with: 2749 / 991

Going ahead to step 7:
When dividing 2749 by 991, we get 2 with a remainder of 767.
Write down 2 as next digit of the result. 
Result so far: 3752.0
If we subtract 1982 from 2749, we get 767.
Bring next digit (6) of the dividend behind the 767 and repeat the process: 7676 / 991

On to step 8:
991 goes into 7676 7 times with a remainder of 739.
Write down 7 as next digit of the result. 
Result so far: 37527.0
If we subtract 6937 from 7676, we get 739.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7390, and continue the process.

Step 9:
When dividing 7390 by 991, we get 7 with a remainder of 453.
Write down 7 as next digit of the result. 
Result so far: 37527.7
The remainder is 453 after subtracting 6937 from 7390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4530, and continue the process.

Moving on to step 10:
991 goes into 4530 4 times with a remainder of 566.
Put 4 as the next digit of the answer. 
Result so far: 37527.74
If we subtract 3964 from 4530, we get 566.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5660, and continue the process.

Let's proceed to step 11:
When dividing 5660 by 991, we get 5 with a remainder of 705.
Put 5 as the next digit of the answer. 
Result so far: 37527.745
Subtract 4955 from 5660 to get 705.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7050, and continue the process.

Step 12:
If we divide 7050 by 991, we get 7 and a remainder of 113.
Put 7 as the next digit of the answer. 
Result so far: 37527.7457
Deduct 6937 from 7050 and we're left with 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Moving on to step 13:
If we divide 1130 by 991, we get 1 and a remainder of 139.
Record the quotient 1 as the next digit in the result. 
Result so far: 37527.74571
Subtract 991 from 1130 to get 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Advancing to step 14:
991 goes into 1390 1 times with a remainder of 399.
Record the quotient 1 as the next digit in the result. 
Result so far: 37527.745711
Subtract 991 from 1390 to get 399.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3990, and continue the process.

The final outcome is 37527.745711, with a leftover of 3.99e-05.
