We're dividing 66886702 by 913 
The aim is to understand the frequency of 913 in 66886702.

On to step 1:
913 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 913

Let's proceed to step 2:
When dividing 66 by 913, we get 0 with a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Grab the next digit (8) from the dividend, add it to 66, then carry on: 668 / 913

Let's proceed to step 3:
668 divided by 913 is 0 with a remainder of 668.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 668, we end up with 668.
Grab the next digit (8) from the dividend, add it to 668, then carry on: 6688 / 913

Let's proceed to step 4:
The number 913 fits into 6688 7 times, leaving a remainder of 297.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we take 6391 away from 6688, we end up with 297.
Take the next digit (6) from the dividend and append it to 297, then repeat: 2976 / 913

Let's proceed to step 5:
2976 divided by 913 is 3 with a remainder of 237.
Put 3 as the next digit of the answer. 
Result so far: 73.0
Subtract 2739 from 2976 to get 237.
Append the next digit (7) from the dividend to 237 and continue with: 2377 / 913

On to step 6:
913 can be fit into 2377 2 times, resulting in a remainder of 551.
The number 2 becomes the next digit in our result. 
Result so far: 732.0
The remainder is 551 after subtracting 1826 from 2377.
Fetch the next digit (0) from the dividend, attach it to 551 and continue: 5510 / 913

Let's proceed to step 7:
When dividing 5510 by 913, we get 6 with a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 7326.0
Deduct 5478 from 5510 and we're left with 32.
Include the next digit (2) from the dividend after 32, then repeat: 322 / 913

Let's proceed to step 8:
The number 913 fits into 322 0 times, leaving a remainder of 322.
Put 0 as the next digit of the answer. 
Result so far: 73260.0
If we take 0 away from 322, we end up with 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Step 9:
913 can be fit into 3220 3 times, resulting in a remainder of 481.
Write down 3 as next digit of the result. 
Result so far: 73260.3
The remainder is 481 after subtracting 2739 from 3220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4810, and continue the process.

Step 10:
The number 913 fits into 4810 5 times, leaving a remainder of 245.
Put 5 as the next digit of the answer. 
Result so far: 73260.35
Deduct 4565 from 4810 and we're left with 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Let's proceed to step 11:
913 can be fit into 2450 2 times, resulting in a remainder of 624.
Put 2 as the next digit of the answer. 
Result so far: 73260.352
If we take 1826 away from 2450, we end up with 624.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

Moving on to step 12:
913 can be fit into 6240 6 times, resulting in a remainder of 762.
Use 6 as the next digit of our solution. 
Result so far: 73260.3526
If we subtract 5478 from 6240, we get 762.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7620, and continue the process.

Step 13:
913 can be fit into 7620 8 times, resulting in a remainder of 316.
Put 8 as the next digit of the answer. 
Result so far: 73260.35268
If we subtract 7304 from 7620, we get 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Let's proceed to step 14:
913 can be fit into 3160 3 times, resulting in a remainder of 421.
Use 3 as the next digit of our solution. 
Result so far: 73260.352683
Subtract 2739 from 3160 to get 421.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4210, and continue the process.

Let's proceed to step 15:
If we divide 4210 by 913, we get 4 and a remainder of 558.
Put 4 as the next digit of the answer. 
Result so far: 73260.3526834
Deduct 3652 from 4210 and we're left with 558.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5580, and continue the process.

Going ahead to step 16:
913 can be fit into 5580 6 times, resulting in a remainder of 102.
The number 6 becomes the next digit in our result. 
Result so far: 73260.35268346
If we subtract 5478 from 5580, we get 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

The final outcome is 73260.35268346, with a leftover of 1.02e-07.
