We're dividing 87783375 by 757 
The aim is to understand the frequency of 757 in 87783375.

On to step 1:
If we divide 8 by 757, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 757

Advancing to step 2:
When dividing 87 by 757, we get 0 with a remainder of 87.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 87 and we're left with 87.
Include the next digit (7) from the dividend after 87, then repeat: 877 / 757

Moving on to step 3:
877 divided by 757 is 1 with a remainder of 120.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 757 from 877 to get 120.
Fetch the next digit (8) from the dividend, attach it to 120 and continue: 1208 / 757

Moving on to step 4:
If we divide 1208 by 757, we get 1 and a remainder of 451.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtract 757 from 1208 to get 451.
Bring next digit (3) of the dividend behind the 451 and repeat the process: 4513 / 757

On to step 5:
The number 757 fits into 4513 5 times, leaving a remainder of 728.
Record the quotient 5 as the next digit in the result. 
Result so far: 115.0
If we subtract 3785 from 4513, we get 728.
Fetch the next digit (3) from the dividend, attach it to 728 and continue: 7283 / 757

On to step 6:
If we divide 7283 by 757, we get 9 and a remainder of 470.
The number 9 becomes the next digit in our result. 
Result so far: 1159.0
Subtract 6813 from 7283 to get 470.
Grab the next digit (7) from the dividend, add it to 470, then carry on: 4707 / 757

Let's proceed to step 7:
757 can be fit into 4707 6 times, resulting in a remainder of 165.
Use 6 as the next digit of our solution. 
Result so far: 11596.0
Deduct 4542 from 4707 and we're left with 165.
Bring next digit (5) of the dividend behind the 165 and repeat the process: 1655 / 757

Going ahead to step 8:
When dividing 1655 by 757, we get 2 with a remainder of 141.
Write down 2 as next digit of the result. 
Result so far: 115962.0
Subtract 1514 from 1655 to get 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Moving on to step 9:
1410 divided by 757 is 1 with a remainder of 653.
Use 1 as the next digit of our solution. 
Result so far: 115962.1
If we take 757 away from 1410, we end up with 653.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6530, and continue the process.

Let's proceed to step 10:
The number 757 fits into 6530 8 times, leaving a remainder of 474.
The next digit of our result is 8. 
Result so far: 115962.18
If we take 6056 away from 6530, we end up with 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

Step 11:
4740 divided by 757 is 6 with a remainder of 198.
The next digit of our result is 6. 
Result so far: 115962.186
Deduct 4542 from 4740 and we're left with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

On to step 12:
1980 divided by 757 is 2 with a remainder of 466.
Use 2 as the next digit of our solution. 
Result so far: 115962.1862
If we take 1514 away from 1980, we end up with 466.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

Going ahead to step 13:
When dividing 4660 by 757, we get 6 with a remainder of 118.
Record the quotient 6 as the next digit in the result. 
Result so far: 115962.18626
Deduct 4542 from 4660 and we're left with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

On to step 14:
The number 757 fits into 1180 1 times, leaving a remainder of 423.
Write down 1 as next digit of the result. 
Result so far: 115962.186261
Subtracting 757 from 1180 leaves us with 423.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4230, and continue the process.

Step 15:
The number 757 fits into 4230 5 times, leaving a remainder of 445.
The number 5 becomes the next digit in our result. 
Result so far: 115962.1862615
Subtract 3785 from 4230 to get 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

On to step 16:
4450 divided by 757 is 5 with a remainder of 665.
The number 5 becomes the next digit in our result. 
Result so far: 115962.18626155
Deduct 3785 from 4450 and we're left with 665.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6650, and continue the process.

The final outcome is 115962.18626155, with a leftover of 6.65e-07.
