30986216 ÷ 356 
The aim is to understand the frequency of 356 in 30986216.

Step 1:
The number 356 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 356

Going ahead to step 2:
30 divided by 356 is 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Take the next digit (9) from the dividend and append it to 30, then repeat: 309 / 356

On to step 3:
When dividing 309 by 356, we get 0 with a remainder of 309.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 309, we get 309.
Bring next digit (8) of the dividend behind the 309 and repeat the process: 3098 / 356

Moving on to step 4:
3098 divided by 356 is 8 with a remainder of 250.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 2848 away from 3098, we end up with 250.
Fetch the next digit (6) from the dividend, attach it to 250 and continue: 2506 / 356

Let's proceed to step 5:
The number 356 fits into 2506 7 times, leaving a remainder of 14.
Write down 7 as next digit of the result. 
Result so far: 87.0
If we take 2492 away from 2506, we end up with 14.
Include the next digit (2) from the dividend after 14, then repeat: 142 / 356

Advancing to step 6:
If we divide 142 by 356, we get 0 and a remainder of 142.
The next digit of our result is 0. 
Result so far: 870.0
Deduct 0 from 142 and we're left with 142.
Bring next digit (1) of the dividend behind the 142 and repeat the process: 1421 / 356

Advancing to step 7:
356 can be fit into 1421 3 times, resulting in a remainder of 353.
The next digit of our result is 3. 
Result so far: 8703.0
Deduct 1068 from 1421 and we're left with 353.
Take the next digit (6) from the dividend and append it to 353, then repeat: 3536 / 356

Advancing to step 8:
356 can be fit into 3536 9 times, resulting in a remainder of 332.
Put 9 as the next digit of the answer. 
Result so far: 87039.0
Deduct 3204 from 3536 and we're left with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

On to step 9:
356 goes into 3320 9 times with a remainder of 116.
The number 9 becomes the next digit in our result. 
Result so far: 87039.9
Deduct 3204 from 3320 and we're left with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Moving on to step 10:
356 can be fit into 1160 3 times, resulting in a remainder of 92.
Put 3 as the next digit of the answer. 
Result so far: 87039.93
Subtracting 1068 from 1160 leaves us 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.

Moving on to step 11:
920 divided by 356 is 2 with a remainder of 208.
Record the quotient 2 as the next digit in the result. 
Result so far: 87039.932
The remainder is 208 after subtracting 712 from 920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Step 12:
If we divide 2080 by 356, we get 5 and a remainder of 300.
The number 5 becomes the next digit in our result. 
Result so far: 87039.9325
If we take 1780 away from 2080, we end up with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

On to step 13:
When dividing 3000 by 356, we get 8 with a remainder of 152.
Record the quotient 8 as the next digit in the result. 
Result so far: 87039.93258
Subtracting 2848 from 3000 leaves us with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Moving on to step 14:
356 can be fit into 1520 4 times, resulting in a remainder of 96.
Put 4 as the next digit of the answer. 
Result so far: 87039.932584
Subtract 1424 from 1520 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Let's proceed to step 15:
356 can be fit into 960 2 times, resulting in a remainder of 248.
Record the quotient 2 as the next digit in the result. 
Result so far: 87039.9325842
The remainder is 248 after subtracting 712 from 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Advancing to step 16:
356 can be fit into 2480 6 times, resulting in a remainder of 344.
Write down 6 as next digit of the result. 
Result so far: 87039.93258426
Subtracting 2136 from 2480 leaves us with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

The quotient of the division is 87039.93258426, and the remainder is 3.44e-07.
