We're dividing 37862691 by 877 
The aim is to understand the frequency of 877 in 37862691.

On to step 1:
877 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 877

Advancing to step 2:
If we divide 37 by 877, we get 0 and a remainder of 37.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 37 to get 37.
Include the next digit (8) from the dividend after 37, then repeat: 378 / 877

Advancing to step 3:
877 goes into 378 0 times with a remainder of 378.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 378, we get 378.
Append the next digit (6) from the dividend to 378 and continue with: 3786 / 877

Going ahead to step 4:
When dividing 3786 by 877, we get 4 with a remainder of 278.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 3508 from 3786 to get 278.
Bring next digit (2) of the dividend behind the 278 and repeat the process: 2782 / 877

Moving on to step 5:
2782 divided by 877 is 3 with a remainder of 151.
The next digit of our result is 3. 
Result so far: 43.0
Deduct 2631 from 2782 and we're left with 151.
Include the next digit (6) from the dividend after 151, then repeat: 1516 / 877

Step 6:
If we divide 1516 by 877, we get 1 and a remainder of 639.
The number 1 becomes the next digit in our result. 
Result so far: 431.0
Deduct 877 from 1516 and we're left with 639.
Take the next digit (9) from the dividend and append it to 639, then repeat: 6399 / 877

Let's proceed to step 7:
The number 877 fits into 6399 7 times, leaving a remainder of 260.
Put 7 as the next digit of the answer. 
Result so far: 4317.0
If we take 6139 away from 6399, we end up with 260.
Grab the next digit (1) from the dividend, add it to 260, then carry on: 2601 / 877

On to step 8:
The number 877 fits into 2601 2 times, leaving a remainder of 847.
Record the quotient 2 as the next digit in the result. 
Result so far: 43172.0
Deduct 1754 from 2601 and we're left with 847.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8470, and continue the process.

Going ahead to step 9:
The number 877 fits into 8470 9 times, leaving a remainder of 577.
The number 9 becomes the next digit in our result. 
Result so far: 43172.9
Subtracting 7893 from 8470 leaves us with 577.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5770, and continue the process.

Advancing to step 10:
877 can be fit into 5770 6 times, resulting in a remainder of 508.
Record the quotient 6 as the next digit in the result. 
Result so far: 43172.96
Deduct 5262 from 5770 and we're left with 508.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

Going ahead to step 11:
877 goes into 5080 5 times with a remainder of 695.
Use 5 as the next digit of our solution. 
Result so far: 43172.965
Subtract 4385 from 5080 to get 695.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6950, and continue the process.

Let's proceed to step 12:
If we divide 6950 by 877, we get 7 and a remainder of 811.
Put 7 as the next digit of the answer. 
Result so far: 43172.9657
The remainder is 811 after subtracting 6139 from 6950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8110, and continue the process.

Going ahead to step 13:
877 goes into 8110 9 times with a remainder of 217.
The next digit of our result is 9. 
Result so far: 43172.96579
The remainder is 217 after subtracting 7893 from 8110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

Moving on to step 14:
877 can be fit into 2170 2 times, resulting in a remainder of 416.
The number 2 becomes the next digit in our result. 
Result so far: 43172.965792
The remainder is 416 after subtracting 1754 from 2170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Let's proceed to step 15:
877 can be fit into 4160 4 times, resulting in a remainder of 652.
The number 4 becomes the next digit in our result. 
Result so far: 43172.9657924
If we take 3508 away from 4160, we end up with 652.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6520, and continue the process.

Going ahead to step 16:
When dividing 6520 by 877, we get 7 with a remainder of 381.
The number 7 becomes the next digit in our result. 
Result so far: 43172.96579247
Deduct 6139 from 6520 and we're left with 381.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3810, and continue the process.

In conclusion, the division gives 43172.96579247 with a balance of 3.81e-07.
