10640621 divided by 416 
The aim is to understand the frequency of 416 in 10640621.

Moving on to step 1:
When dividing 1 by 416, we get 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.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 416

Step 2:
416 goes into 10 0 times with a remainder of 10.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 10, we get 10.
Bring next digit (6) of the dividend behind the 10 and repeat the process: 106 / 416

Let's proceed to step 3:
416 can be fit into 106 0 times, resulting in a remainder of 106.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 106 and we're left with 106.
Take the next digit (4) from the dividend and append it to 106, then repeat: 1064 / 416

Going ahead to step 4:
416 goes into 1064 2 times with a remainder of 232.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 832 from 1064 and we're left with 232.
Append the next digit (0) from the dividend to 232 and continue with: 2320 / 416

On to step 5:
2320 divided by 416 is 5 with a remainder of 240.
Use 5 as the next digit of our solution. 
Result so far: 25.0
If we take 2080 away from 2320, we end up with 240.
Append the next digit (6) from the dividend to 240 and continue with: 2406 / 416

On to step 6:
416 goes into 2406 5 times with a remainder of 326.
The next digit of our result is 5. 
Result so far: 255.0
Subtracting 2080 from 2406 leaves us with 326.
Take the next digit (2) from the dividend and append it to 326, then repeat: 3262 / 416

Moving on to step 7:
3262 divided by 416 is 7 with a remainder of 350.
Record the quotient 7 as the next digit in the result. 
Result so far: 2557.0
If we subtract 2912 from 3262, we get 350.
Include the next digit (1) from the dividend after 350, then repeat: 3501 / 416

Step 8:
If we divide 3501 by 416, we get 8 and a remainder of 173.
The number 8 becomes the next digit in our result. 
Result so far: 25578.0
Deduct 3328 from 3501 and we're left with 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

Moving on to step 9:
1730 divided by 416 is 4 with a remainder of 66.
The next digit of our result is 4. 
Result so far: 25578.4
Subtract 1664 from 1730 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 10:
The number 416 fits into 660 1 times, leaving a remainder of 244.
Put 1 as the next digit of the answer. 
Result so far: 25578.41
If we subtract 416 from 660, we 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.

Step 11:
If we divide 2440 by 416, we get 5 and a remainder of 360.
Use 5 as the next digit of our solution. 
Result so far: 25578.415
Deduct 2080 from 2440 and we're left with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Step 12:
When dividing 3600 by 416, we get 8 with a remainder of 272.
The number 8 becomes the next digit in our result. 
Result so far: 25578.4158
The remainder is 272 after subtracting 3328 from 3600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Moving on to step 13:
2720 divided by 416 is 6 with a remainder of 224.
The next digit of our result is 6. 
Result so far: 25578.41586
If we subtract 2496 from 2720, we get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Moving on to step 14:
The number 416 fits into 2240 5 times, leaving a remainder of 160.
The next digit of our result is 5. 
Result so far: 25578.415865
Subtract 2080 from 2240 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 15:
When dividing 1600 by 416, we get 3 with a remainder of 352.
Put 3 as the next digit of the answer. 
Result so far: 25578.4158653
Deduct 1248 from 1600 and we're left with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

On to step 16:
416 can be fit into 3520 8 times, resulting in a remainder of 192.
Write down 8 as next digit of the result. 
Result so far: 25578.41586538
Subtracting 3328 from 3520 leaves us with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Our division results in 25578.41586538 with a remaining 1.92e-07.
