We divide 94172992 by 646
The aim is to understand the frequency of 646 in 94172992.

Moving on to step 1:
If we divide 9 by 646, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Bring next digit (4) of the dividend behind the 9 and repeat the process: 94 / 646

Let's proceed to step 2:
94 divided by 646 is 0 with a remainder of 94.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 94 to get 94.
Include the next digit (1) from the dividend after 94, then repeat: 941 / 646

Step 3:
If we divide 941 by 646, we get 1 and a remainder of 295.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 295 after subtracting 646 from 941.
Append the next digit (7) from the dividend to 295 and continue with: 2957 / 646

Moving on to step 4:
If we divide 2957 by 646, we get 4 and a remainder of 373.
Write down 4 as next digit of the result. 
Result so far: 14.0
If we subtract 2584 from 2957, we get 373.
Include the next digit (2) from the dividend after 373, then repeat: 3732 / 646

On to step 5:
If we divide 3732 by 646, we get 5 and a remainder of 502.
Write down 5 as next digit of the result. 
Result so far: 145.0
If we take 3230 away from 3732, we end up with 502.
Take the next digit (9) from the dividend and append it to 502, then repeat: 5029 / 646

Let's proceed to step 6:
646 goes into 5029 7 times with a remainder of 507.
The next digit of our result is 7. 
Result so far: 1457.0
Subtract 4522 from 5029 to get 507.
Fetch the next digit (9) from the dividend, attach it to 507 and continue: 5079 / 646

On to step 7:
5079 divided by 646 is 7 with a remainder of 557.
The number 7 becomes the next digit in our result. 
Result so far: 14577.0
Subtract 4522 from 5079 to get 557.
Take the next digit (2) from the dividend and append it to 557, then repeat: 5572 / 646

Advancing to step 8:
646 goes into 5572 8 times with a remainder of 404.
Put 8 as the next digit of the answer. 
Result so far: 145778.0
Subtracting 5168 from 5572 leaves us with 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Step 9:
4040 divided by 646 is 6 with a remainder of 164.
Put 6 as the next digit of the answer. 
Result so far: 145778.6
Subtract 3876 from 4040 to get 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Advancing to step 10:
If we divide 1640 by 646, we get 2 and a remainder of 348.
Write down 2 as next digit of the result. 
Result so far: 145778.62
If we subtract 1292 from 1640, we get 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Moving on to step 11:
If we divide 3480 by 646, we get 5 and a remainder of 250.
The number 5 becomes the next digit in our result. 
Result so far: 145778.625
If we take 3230 away from 3480, we end up with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Advancing to step 12:
646 can be fit into 2500 3 times, resulting in a remainder of 562.
Use 3 as the next digit of our solution. 
Result so far: 145778.6253
Subtract 1938 from 2500 to get 562.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5620, and continue the process.

Let's proceed to step 13:
When dividing 5620 by 646, we get 8 with a remainder of 452.
Write down 8 as next digit of the result. 
Result so far: 145778.62538
If we subtract 5168 from 5620, we get 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Advancing to step 14:
When dividing 4520 by 646, we get 6 with a remainder of 644.
Record the quotient 6 as the next digit in the result. 
Result so far: 145778.625386
Deduct 3876 from 4520 and we're left with 644.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6440, and continue the process.

Advancing to step 15:
6440 divided by 646 is 9 with a remainder of 626.
Write down 9 as next digit of the result. 
Result so far: 145778.6253869
If we subtract 5814 from 6440, we get 626.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6260, and continue the process.

Step 16:
When dividing 6260 by 646, we get 9 with a remainder of 446.
The next digit of our result is 9. 
Result so far: 145778.62538699
If we take 5814 away from 6260, we end up with 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

After the division, we end up with 145778.62538699 and a remainder of 4.46e-07.
