83603810 ÷ 356 
The aim is to understand the frequency of 356 in 83603810.

On to step 1:
8 divided by 356 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 356

Advancing to step 2:
If we divide 83 by 356, we get 0 and a remainder of 83.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 83 to get 83.
Grab the next digit (6) from the dividend, add it to 83, then carry on: 836 / 356

On to step 3:
836 divided by 356 is 2 with a remainder of 124.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 712 from 836 to get 124.
Take the next digit (0) from the dividend and append it to 124, then repeat: 1240 / 356

Going ahead to step 4:
356 goes into 1240 3 times with a remainder of 172.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
If we subtract 1068 from 1240, we get 172.
Take the next digit (3) from the dividend and append it to 172, then repeat: 1723 / 356

Let's proceed to step 5:
The number 356 fits into 1723 4 times, leaving a remainder of 299.
Record the quotient 4 as the next digit in the result. 
Result so far: 234.0
If we take 1424 away from 1723, we end up with 299.
Append the next digit (8) from the dividend to 299 and continue with: 2998 / 356

Advancing to step 6:
356 goes into 2998 8 times with a remainder of 150.
Write down 8 as next digit of the result. 
Result so far: 2348.0
If we take 2848 away from 2998, we end up with 150.
Append the next digit (1) from the dividend to 150 and continue with: 1501 / 356

Let's proceed to step 7:
If we divide 1501 by 356, we get 4 and a remainder of 77.
Use 4 as the next digit of our solution. 
Result so far: 23484.0
The remainder is 77 after subtracting 1424 from 1501.
Grab the next digit (0) from the dividend, add it to 77, then carry on: 770 / 356

Moving on to step 8:
If we divide 770 by 356, we get 2 and a remainder of 58.
The next digit of our result is 2. 
Result so far: 234842.0
Deduct 712 from 770 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 9:
580 divided by 356 is 1 with a remainder of 224.
Record the quotient 1 as the next digit in the result. 
Result so far: 234842.1
Deduct 356 from 580 and we're left with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Going ahead to step 10:
The number 356 fits into 2240 6 times, leaving a remainder of 104.
Record the quotient 6 as the next digit in the result. 
Result so far: 234842.16
Subtract 2136 from 2240 to get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Step 11:
The number 356 fits into 1040 2 times, leaving a remainder of 328.
The next digit of our result is 2. 
Result so far: 234842.162
The remainder is 328 after subtracting 712 from 1040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Going ahead to step 12:
356 goes into 3280 9 times with a remainder of 76.
Put 9 as the next digit of the answer. 
Result so far: 234842.1629
Deduct 3204 from 3280 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 13:
356 can be fit into 760 2 times, resulting in a remainder of 48.
The next digit of our result is 2. 
Result so far: 234842.16292
If we take 712 away from 760, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 14:
When dividing 480 by 356, we get 1 with a remainder of 124.
The number 1 becomes the next digit in our result. 
Result so far: 234842.162921
The remainder is 124 after subtracting 356 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Step 15:
When dividing 1240 by 356, we get 3 with a remainder of 172.
Put 3 as the next digit of the answer. 
Result so far: 234842.1629213
Deduct 1068 from 1240 and we're left with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Moving on to step 16:
356 goes into 1720 4 times with a remainder of 296.
The next digit of our result is 4. 
Result so far: 234842.16292134
If we take 1424 away from 1720, we end up with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

The final outcome is 234842.16292134, with a leftover of 2.96e-07.
