We're dividing 76331389 by 913 
The aim is to understand the frequency of 913 in 76331389.

Moving on to step 1:
When dividing 7 by 913, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (6) from the dividend and append it to 7, then repeat: 76 / 913

Going ahead to step 2:
913 can be fit into 76 0 times, resulting in a remainder of 76.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 76 to get 76.
Fetch the next digit (3) from the dividend, attach it to 76 and continue: 763 / 913

Let's proceed to step 3:
If we divide 763 by 913, we get 0 and a remainder of 763.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 763, we get 763.
Bring next digit (3) of the dividend behind the 763 and repeat the process: 7633 / 913

Advancing to step 4:
If we divide 7633 by 913, we get 8 and a remainder of 329.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtract 7304 from 7633 to get 329.
Grab the next digit (1) from the dividend, add it to 329, then carry on: 3291 / 913

Advancing to step 5:
When dividing 3291 by 913, we get 3 with a remainder of 552.
The number 3 becomes the next digit in our result. 
Result so far: 83.0
Subtract 2739 from 3291 to get 552.
Include the next digit (3) from the dividend after 552, then repeat: 5523 / 913

Advancing to step 6:
5523 divided by 913 is 6 with a remainder of 45.
Put 6 as the next digit of the answer. 
Result so far: 836.0
Subtracting 5478 from 5523 leaves us with 45.
Bring next digit (8) of the dividend behind the 45 and repeat the process: 458 / 913

Going ahead to step 7:
When dividing 458 by 913, we get 0 with a remainder of 458.
The number 0 becomes the next digit in our result. 
Result so far: 8360.0
Subtracting 0 from 458 leaves us with 458.
Fetch the next digit (9) from the dividend, attach it to 458 and continue: 4589 / 913

On to step 8:
4589 divided by 913 is 5 with a remainder of 24.
Record the quotient 5 as the next digit in the result. 
Result so far: 83605.0
If we take 4565 away from 4589, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 9:
240 divided by 913 is 0 with a remainder of 240.
Use 0 as the next digit of our solution. 
Result so far: 83605.0
Subtracting 0 from 240 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 10:
913 can be fit into 2400 2 times, resulting in a remainder of 574.
The next digit of our result is 2. 
Result so far: 83605.02
If we subtract 1826 from 2400, we get 574.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5740, and continue the process.

Advancing to step 11:
5740 divided by 913 is 6 with a remainder of 262.
The next digit of our result is 6. 
Result so far: 83605.026
Subtracting 5478 from 5740 leaves us with 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Step 12:
913 goes into 2620 2 times with a remainder of 794.
Put 2 as the next digit of the answer. 
Result so far: 83605.0262
Subtract 1826 from 2620 to get 794.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7940, and continue the process.

Step 13:
The number 913 fits into 7940 8 times, leaving a remainder of 636.
Record the quotient 8 as the next digit in the result. 
Result so far: 83605.02628
If we take 7304 away from 7940, we end up with 636.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

Moving on to step 14:
913 can be fit into 6360 6 times, resulting in a remainder of 882.
Write down 6 as next digit of the result. 
Result so far: 83605.026286
If we take 5478 away from 6360, we end up with 882.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8820, and continue the process.

Advancing to step 15:
The number 913 fits into 8820 9 times, leaving a remainder of 603.
Put 9 as the next digit of the answer. 
Result so far: 83605.0262869
If we take 8217 away from 8820, we end up with 603.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6030, and continue the process.

Going ahead to step 16:
The number 913 fits into 6030 6 times, leaving a remainder of 552.
Write down 6 as next digit of the result. 
Result so far: 83605.02628696
Subtract 5478 from 6030 to get 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

Our division results in 83605.02628696 with a remaining 5.52e-07.
