We divide 91317020 by 402
The aim is to understand the frequency of 402 in 91317020.

Advancing to step 1:
If we divide 9 by 402, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 402

Step 2:
402 goes into 91 0 times with a remainder of 91.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 91, we get 91.
Include the next digit (3) from the dividend after 91, then repeat: 913 / 402

Going ahead to step 3:
When dividing 913 by 402, we get 2 with a remainder of 109.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 804 from 913, we get 109.
Include the next digit (1) from the dividend after 109, then repeat: 1091 / 402

On to step 4:
1091 divided by 402 is 2 with a remainder of 287.
Put 2 as the next digit of the answer. 
Result so far: 22.0
Deduct 804 from 1091 and we're left with 287.
Bring next digit (7) of the dividend behind the 287 and repeat the process: 2877 / 402

On to step 5:
402 can be fit into 2877 7 times, resulting in a remainder of 63.
Put 7 as the next digit of the answer. 
Result so far: 227.0
If we subtract 2814 from 2877, we get 63.
Take the next digit (0) from the dividend and append it to 63, then repeat: 630 / 402

Advancing to step 6:
630 divided by 402 is 1 with a remainder of 228.
Record the quotient 1 as the next digit in the result. 
Result so far: 2271.0
The remainder is 228 after subtracting 402 from 630.
Grab the next digit (2) from the dividend, add it to 228, then carry on: 2282 / 402

Advancing to step 7:
402 goes into 2282 5 times with a remainder of 272.
Record the quotient 5 as the next digit in the result. 
Result so far: 22715.0
Subtract 2010 from 2282 to get 272.
Take the next digit (0) from the dividend and append it to 272, then repeat: 2720 / 402

Advancing to step 8:
402 can be fit into 2720 6 times, resulting in a remainder of 308.
Write down 6 as next digit of the result. 
Result so far: 227156.0
Subtracting 2412 from 2720 leaves us with 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Moving on to step 9:
402 goes into 3080 7 times with a remainder of 266.
Write down 7 as next digit of the result. 
Result so far: 227156.7
Deduct 2814 from 3080 and we're left with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Step 10:
If we divide 2660 by 402, we get 6 and a remainder of 248.
The next digit of our result is 6. 
Result so far: 227156.76
If we subtract 2412 from 2660, we get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Step 11:
When dividing 2480 by 402, we get 6 with a remainder of 68.
Record the quotient 6 as the next digit in the result. 
Result so far: 227156.766
If we subtract 2412 from 2480, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

In conclusion, the division gives 227156.766 with a balance of 0.0068.
