We're dividing 35741583 by 877 
The aim is to understand the frequency of 877 in 35741583.

Step 1:
When dividing 3 by 877, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 877

Let's proceed to step 2:
When dividing 35 by 877, we get 0 with a remainder of 35.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 35 and we're left with 35.
Take the next digit (7) from the dividend and append it to 35, then repeat: 357 / 877

Step 3:
877 goes into 357 0 times with a remainder of 357.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 357 leaves us with 357.
Include the next digit (4) from the dividend after 357, then repeat: 3574 / 877

Going ahead to step 4:
When dividing 3574 by 877, we get 4 with a remainder of 66.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 3508 away from 3574, we end up with 66.
Bring next digit (1) of the dividend behind the 66 and repeat the process: 661 / 877

Moving on to step 5:
661 divided by 877 is 0 with a remainder of 661.
The number 0 becomes the next digit in our result. 
Result so far: 40.0
The remainder is 661 after subtracting 0 from 661.
Grab the next digit (5) from the dividend, add it to 661, then carry on: 6615 / 877

Step 6:
6615 divided by 877 is 7 with a remainder of 476.
Use 7 as the next digit of our solution. 
Result so far: 407.0
Subtracting 6139 from 6615 leaves us with 476.
Fetch the next digit (8) from the dividend, attach it to 476 and continue: 4768 / 877

Moving on to step 7:
When dividing 4768 by 877, we get 5 with a remainder of 383.
Write down 5 as next digit of the result. 
Result so far: 4075.0
If we subtract 4385 from 4768, we get 383.
Grab the next digit (3) from the dividend, add it to 383, then carry on: 3833 / 877

Moving on to step 8:
When dividing 3833 by 877, we get 4 with a remainder of 325.
Record the quotient 4 as the next digit in the result. 
Result so far: 40754.0
The remainder is 325 after subtracting 3508 from 3833.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

On to step 9:
877 goes into 3250 3 times with a remainder of 619.
Put 3 as the next digit of the answer. 
Result so far: 40754.3
The remainder is 619 after subtracting 2631 from 3250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6190, and continue the process.

Advancing to step 10:
The number 877 fits into 6190 7 times, leaving a remainder of 51.
The number 7 becomes the next digit in our result. 
Result so far: 40754.37
Subtracting 6139 from 6190 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 11:
If we divide 510 by 877, we get 0 and a remainder of 510.
The next digit of our result is 0. 
Result so far: 40754.37
The remainder is 510 after subtracting 0 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Moving on to step 12:
When dividing 5100 by 877, we get 5 with a remainder of 715.
Record the quotient 5 as the next digit in the result. 
Result so far: 40754.3705
The remainder is 715 after subtracting 4385 from 5100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7150, and continue the process.

Let's proceed to step 13:
If we divide 7150 by 877, we get 8 and a remainder of 134.
Put 8 as the next digit of the answer. 
Result so far: 40754.37058
Deduct 7016 from 7150 and we're left with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Going ahead to step 14:
If we divide 1340 by 877, we get 1 and a remainder of 463.
Write down 1 as next digit of the result. 
Result so far: 40754.370581
Deduct 877 from 1340 and we're left with 463.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4630, and continue the process.

Moving on to step 15:
The number 877 fits into 4630 5 times, leaving a remainder of 245.
Record the quotient 5 as the next digit in the result. 
Result so far: 40754.3705815
Subtracting 4385 from 4630 leaves us 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 16:
The number 877 fits into 2450 2 times, leaving a remainder of 696.
The number 2 becomes the next digit in our result. 
Result so far: 40754.37058152
Subtracting 1754 from 2450 leaves us with 696.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6960, and continue the process.

The final outcome is 40754.37058152, with a leftover of 6.96e-07.
