81337229 ÷ 557 
The aim is to understand the frequency of 557 in 81337229.

On to step 1:
557 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 557

On to step 2:
The number 557 fits into 81 0 times, leaving a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Grab the next digit (3) from the dividend, add it to 81, then carry on: 813 / 557

On to step 3:
813 divided by 557 is 1 with a remainder of 256.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 557 from 813 and we're left with 256.
Take the next digit (3) from the dividend and append it to 256, then repeat: 2563 / 557

Going ahead to step 4:
2563 divided by 557 is 4 with a remainder of 335.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Subtract 2228 from 2563 to get 335.
Bring next digit (7) of the dividend behind the 335 and repeat the process: 3357 / 557

Going ahead to step 5:
If we divide 3357 by 557, we get 6 and a remainder of 15.
Record the quotient 6 as the next digit in the result. 
Result so far: 146.0
Deduct 3342 from 3357 and we're left with 15.
Bring next digit (2) of the dividend behind the 15 and repeat the process: 152 / 557

Step 6:
557 can be fit into 152 0 times, resulting in a remainder of 152.
Put 0 as the next digit of the answer. 
Result so far: 1460.0
If we take 0 away from 152, we end up with 152.
Grab the next digit (2) from the dividend, add it to 152, then carry on: 1522 / 557

Going ahead to step 7:
1522 divided by 557 is 2 with a remainder of 408.
Write down 2 as next digit of the result. 
Result so far: 14602.0
If we take 1114 away from 1522, we end up with 408.
Take the next digit (9) from the dividend and append it to 408, then repeat: 4089 / 557

On to step 8:
If we divide 4089 by 557, we get 7 and a remainder of 190.
Put 7 as the next digit of the answer. 
Result so far: 146027.0
Deduct 3899 from 4089 and we're left with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Step 9:
When dividing 1900 by 557, we get 3 with a remainder of 229.
Record the quotient 3 as the next digit in the result. 
Result so far: 146027.3
If we subtract 1671 from 1900, we get 229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

Step 10:
When dividing 2290 by 557, we get 4 with a remainder of 62.
Use 4 as the next digit of our solution. 
Result so far: 146027.34
Deduct 2228 from 2290 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 11:
When dividing 620 by 557, we get 1 with a remainder of 63.
Write down 1 as next digit of the result. 
Result so far: 146027.341
Subtract 557 from 620 to get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

On to step 12:
557 goes into 630 1 times with a remainder of 73.
Write down 1 as next digit of the result. 
Result so far: 146027.3411
If we take 557 away from 630, we end up with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

After the division, we end up with 146027.3411 and a remainder of 0.00073.
