We're dividing 91152994 by 357 
The aim is to understand the frequency of 357 in 91152994.

Step 1:
The number 357 fits into 9 0 times, leaving a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 357

Going ahead to step 2:
91 divided by 357 is 0 with a remainder of 91.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 91, we get 91.
Take the next digit (1) from the dividend and append it to 91, then repeat: 911 / 357

On to step 3:
The number 357 fits into 911 2 times, leaving a remainder of 197.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 714 from 911 to get 197.
Bring next digit (5) of the dividend behind the 197 and repeat the process: 1975 / 357

On to step 4:
357 can be fit into 1975 5 times, resulting in a remainder of 190.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
If we take 1785 away from 1975, we end up with 190.
Take the next digit (2) from the dividend and append it to 190, then repeat: 1902 / 357

Advancing to step 5:
If we divide 1902 by 357, we get 5 and a remainder of 117.
Put 5 as the next digit of the answer. 
Result so far: 255.0
The remainder is 117 after subtracting 1785 from 1902.
Grab the next digit (9) from the dividend, add it to 117, then carry on: 1179 / 357

Let's proceed to step 6:
The number 357 fits into 1179 3 times, leaving a remainder of 108.
The number 3 becomes the next digit in our result. 
Result so far: 2553.0
If we subtract 1071 from 1179, we get 108.
Take the next digit (9) from the dividend and append it to 108, then repeat: 1089 / 357

Going ahead to step 7:
357 goes into 1089 3 times with a remainder of 18.
Write down 3 as next digit of the result. 
Result so far: 25533.0
The remainder is 18 after subtracting 1071 from 1089.
Grab the next digit (4) from the dividend, add it to 18, then carry on: 184 / 357

Let's proceed to step 8:
If we divide 184 by 357, we get 0 and a remainder of 184.
The number 0 becomes the next digit in our result. 
Result so far: 255330.0
Deduct 0 from 184 and we're left with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Going ahead to step 9:
357 goes into 1840 5 times with a remainder of 55.
The next digit of our result is 5. 
Result so far: 255330.5
The remainder is 55 after subtracting 1785 from 1840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 10:
If we divide 550 by 357, we get 1 and a remainder of 193.
The next digit of our result is 1. 
Result so far: 255330.51
Subtract 357 from 550 to get 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

Going ahead to step 11:
357 goes into 1930 5 times with a remainder of 145.
The next digit of our result is 5. 
Result so far: 255330.515
Subtract 1785 from 1930 to get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Step 12:
If we divide 1450 by 357, we get 4 and a remainder of 22.
The number 4 becomes the next digit in our result. 
Result so far: 255330.5154
Subtracting 1428 from 1450 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 13:
220 divided by 357 is 0 with a remainder of 220.
Use 0 as the next digit of our solution. 
Result so far: 255330.5154
If we take 0 away from 220, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Step 14:
When dividing 2200 by 357, we get 6 with a remainder of 58.
Record the quotient 6 as the next digit in the result. 
Result so far: 255330.515406
Deduct 2142 from 2200 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 15:
If we divide 580 by 357, we get 1 and a remainder of 223.
Write down 1 as next digit of the result. 
Result so far: 255330.5154061
If we take 357 away from 580, we end up with 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

Let's proceed to step 16:
The number 357 fits into 2230 6 times, leaving a remainder of 88.
Put 6 as the next digit of the answer. 
Result so far: 255330.51540616
The remainder is 88 after subtracting 2142 from 2230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

The final outcome is 255330.51540616, with a leftover of 8.8e-08.
