Let's divide 37975006 by 921
The aim is to understand the frequency of 921 in 37975006.

Going ahead to step 1:
921 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 921

Step 2:
The number 921 fits into 37 0 times, leaving a remainder of 37.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 37, we get 37.
Include the next digit (9) from the dividend after 37, then repeat: 379 / 921

Let's proceed to step 3:
The number 921 fits into 379 0 times, leaving a remainder of 379.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 379 and we're left with 379.
Include the next digit (7) from the dividend after 379, then repeat: 3797 / 921

Step 4:
921 can be fit into 3797 4 times, resulting in a remainder of 113.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 113 after subtracting 3684 from 3797.
Grab the next digit (5) from the dividend, add it to 113, then carry on: 1135 / 921

On to step 5:
When dividing 1135 by 921, we get 1 with a remainder of 214.
Record the quotient 1 as the next digit in the result. 
Result so far: 41.0
If we subtract 921 from 1135, we get 214.
Take the next digit (0) from the dividend and append it to 214, then repeat: 2140 / 921

Step 6:
When dividing 2140 by 921, we get 2 with a remainder of 298.
Use 2 as the next digit of our solution. 
Result so far: 412.0
Deduct 1842 from 2140 and we're left with 298.
Append the next digit (0) from the dividend to 298 and continue with: 2980 / 921

On to step 7:
2980 divided by 921 is 3 with a remainder of 217.
Use 3 as the next digit of our solution. 
Result so far: 4123.0
Deduct 2763 from 2980 and we're left with 217.
Bring next digit (6) of the dividend behind the 217 and repeat the process: 2176 / 921

Step 8:
When dividing 2176 by 921, we get 2 with a remainder of 334.
The number 2 becomes the next digit in our result. 
Result so far: 41232.0
Subtract 1842 from 2176 to get 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Let's proceed to step 9:
921 goes into 3340 3 times with a remainder of 577.
Put 3 as the next digit of the answer. 
Result so far: 41232.3
Deduct 2763 from 3340 and we're left with 577.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5770, and continue the process.

Moving on to step 10:
921 goes into 5770 6 times with a remainder of 244.
Record the quotient 6 as the next digit in the result. 
Result so far: 41232.36
Subtract 5526 from 5770 to get 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

On to step 11:
If we divide 2440 by 921, we get 2 and a remainder of 598.
Record the quotient 2 as the next digit in the result. 
Result so far: 41232.362
Deduct 1842 from 2440 and we're left with 598.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5980, and continue the process.

Let's proceed to step 12:
If we divide 5980 by 921, we get 6 and a remainder of 454.
The next digit of our result is 6. 
Result so far: 41232.3626
Subtracting 5526 from 5980 leaves us with 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

On to step 13:
If we divide 4540 by 921, we get 4 and a remainder of 856.
Write down 4 as next digit of the result. 
Result so far: 41232.36264
Subtract 3684 from 4540 to get 856.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8560, and continue the process.

Advancing to step 14:
If we divide 8560 by 921, we get 9 and a remainder of 271.
The number 9 becomes the next digit in our result. 
Result so far: 41232.362649
If we subtract 8289 from 8560, we get 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

Moving on to step 15:
2710 divided by 921 is 2 with a remainder of 868.
The number 2 becomes the next digit in our result. 
Result so far: 41232.3626492
If we take 1842 away from 2710, we end up with 868.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8680, and continue the process.

Step 16:
If we divide 8680 by 921, we get 9 and a remainder of 391.
The next digit of our result is 9. 
Result so far: 41232.36264929
Deduct 8289 from 8680 and we're left with 391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

After the division, we end up with 41232.36264929 and a remainder of 3.91e-07.
