21641335 divided by 346 
The aim is to understand the frequency of 346 in 21641335.

Let's proceed to step 1:
The number 346 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 346

Let's proceed to step 2:
The number 346 fits into 21 0 times, leaving a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Bring next digit (6) of the dividend behind the 21 and repeat the process: 216 / 346

Going ahead to step 3:
346 can be fit into 216 0 times, resulting in a remainder of 216.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 216 and we're left with 216.
Bring next digit (4) of the dividend behind the 216 and repeat the process: 2164 / 346

On to step 4:
When dividing 2164 by 346, we get 6 with a remainder of 88.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we take 2076 away from 2164, we end up with 88.
Append the next digit (1) from the dividend to 88 and continue with: 881 / 346

Going ahead to step 5:
The number 346 fits into 881 2 times, leaving a remainder of 189.
Use 2 as the next digit of our solution. 
Result so far: 62.0
If we subtract 692 from 881, we get 189.
Include the next digit (3) from the dividend after 189, then repeat: 1893 / 346

Going ahead to step 6:
The number 346 fits into 1893 5 times, leaving a remainder of 163.
Write down 5 as next digit of the result. 
Result so far: 625.0
If we take 1730 away from 1893, we end up with 163.
Grab the next digit (3) from the dividend, add it to 163, then carry on: 1633 / 346

Step 7:
When dividing 1633 by 346, we get 4 with a remainder of 249.
Put 4 as the next digit of the answer. 
Result so far: 6254.0
Deduct 1384 from 1633 and we're left with 249.
Grab the next digit (5) from the dividend, add it to 249, then carry on: 2495 / 346

Going ahead to step 8:
346 can be fit into 2495 7 times, resulting in a remainder of 73.
Write down 7 as next digit of the result. 
Result so far: 62547.0
Deduct 2422 from 2495 and we're left with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

On to step 9:
The number 346 fits into 730 2 times, leaving a remainder of 38.
Use 2 as the next digit of our solution. 
Result so far: 62547.2
Subtracting 692 from 730 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 10:
380 divided by 346 is 1 with a remainder of 34.
Write down 1 as next digit of the result. 
Result so far: 62547.21
If we take 346 away from 380, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 11:
346 can be fit into 340 0 times, resulting in a remainder of 340.
Use 0 as the next digit of our solution. 
Result so far: 62547.21
If we subtract 0 from 340, we get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Moving on to step 12:
346 can be fit into 3400 9 times, resulting in a remainder of 286.
The next digit of our result is 9. 
Result so far: 62547.2109
Subtract 3114 from 3400 to get 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Step 13:
If we divide 2860 by 346, we get 8 and a remainder of 92.
Put 8 as the next digit of the answer. 
Result so far: 62547.21098
Deduct 2768 from 2860 and we're left with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Going ahead to step 14:
The number 346 fits into 920 2 times, leaving a remainder of 228.
Use 2 as the next digit of our solution. 
Result so far: 62547.210982
Deduct 692 from 920 and we're left with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Going ahead to step 15:
When dividing 2280 by 346, we get 6 with a remainder of 204.
The number 6 becomes the next digit in our result. 
Result so far: 62547.2109826
Subtracting 2076 from 2280 leaves us with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Let's proceed to step 16:
When dividing 2040 by 346, we get 5 with a remainder of 310.
Write down 5 as next digit of the result. 
Result so far: 62547.21098265
Deduct 1730 from 2040 and we're left with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

After the division, we end up with 62547.21098265 and a remainder of 3.1e-07.
