We're dividing 15685074 by 356 
The aim is to understand the frequency of 356 in 15685074.

Advancing to step 1:
When dividing 1 by 356, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 356

On to step 2:
356 goes into 15 0 times with a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Fetch the next digit (6) from the dividend, attach it to 15 and continue: 156 / 356

Let's proceed to step 3:
If we divide 156 by 356, we get 0 and a remainder of 156.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 156, we end up with 156.
Fetch the next digit (8) from the dividend, attach it to 156 and continue: 1568 / 356

Going ahead to step 4:
356 can be fit into 1568 4 times, resulting in a remainder of 144.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 144 after subtracting 1424 from 1568.
Grab the next digit (5) from the dividend, add it to 144, then carry on: 1445 / 356

On to step 5:
When dividing 1445 by 356, we get 4 with a remainder of 21.
Write down 4 as next digit of the result. 
Result so far: 44.0
Subtract 1424 from 1445 to get 21.
Fetch the next digit (0) from the dividend, attach it to 21 and continue: 210 / 356

Going ahead to step 6:
If we divide 210 by 356, we get 0 and a remainder of 210.
Record the quotient 0 as the next digit in the result. 
Result so far: 440.0
If we subtract 0 from 210, we get 210.
Bring next digit (7) of the dividend behind the 210 and repeat the process: 2107 / 356

Let's proceed to step 7:
The number 356 fits into 2107 5 times, leaving a remainder of 327.
Use 5 as the next digit of our solution. 
Result so far: 4405.0
Subtracting 1780 from 2107 leaves us with 327.
Append the next digit (4) from the dividend to 327 and continue with: 3274 / 356

Moving on to step 8:
3274 divided by 356 is 9 with a remainder of 70.
Record the quotient 9 as the next digit in the result. 
Result so far: 44059.0
Subtracting 3204 from 3274 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 9:
700 divided by 356 is 1 with a remainder of 344.
Write down 1 as next digit of the result. 
Result so far: 44059.1
If we take 356 away from 700, we end up 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.

On to step 10:
The number 356 fits into 3440 9 times, leaving a remainder of 236.
Use 9 as the next digit of our solution. 
Result so far: 44059.19
If we take 3204 away from 3440, we end up with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Step 11:
356 goes into 2360 6 times with a remainder of 224.
Put 6 as the next digit of the answer. 
Result so far: 44059.196
Subtract 2136 from 2360 to 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 12:
If we divide 2240 by 356, we get 6 and a remainder of 104.
Use 6 as the next digit of our solution. 
Result so far: 44059.1966
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.

The quotient of the division is 44059.1966, and the remainder is 0.00104.
