We're dividing 98958671 by 887 
The aim is to understand the frequency of 887 in 98958671.

On to step 1:
887 goes into 9 0 times with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 887

Step 2:
When dividing 98 by 887, we get 0 with a remainder of 98.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 98 to get 98.
Include the next digit (9) from the dividend after 98, then repeat: 989 / 887

On to step 3:
887 can be fit into 989 1 times, resulting in a remainder of 102.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 887 from 989 and we're left with 102.
Append the next digit (5) from the dividend to 102 and continue with: 1025 / 887

Advancing to step 4:
887 goes into 1025 1 times with a remainder of 138.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtracting 887 from 1025 leaves us with 138.
Append the next digit (8) from the dividend to 138 and continue with: 1388 / 887

Step 5:
When dividing 1388 by 887, we get 1 with a remainder of 501.
Put 1 as the next digit of the answer. 
Result so far: 111.0
If we subtract 887 from 1388, we get 501.
Take the next digit (6) from the dividend and append it to 501, then repeat: 5016 / 887

On to step 6:
If we divide 5016 by 887, we get 5 and a remainder of 581.
Record the quotient 5 as the next digit in the result. 
Result so far: 1115.0
If we take 4435 away from 5016, we end up with 581.
Fetch the next digit (7) from the dividend, attach it to 581 and continue: 5817 / 887

Going ahead to step 7:
The number 887 fits into 5817 6 times, leaving a remainder of 495.
The next digit of our result is 6. 
Result so far: 11156.0
Deduct 5322 from 5817 and we're left with 495.
Bring next digit (1) of the dividend behind the 495 and repeat the process: 4951 / 887

Step 8:
When dividing 4951 by 887, we get 5 with a remainder of 516.
Record the quotient 5 as the next digit in the result. 
Result so far: 111565.0
Deduct 4435 from 4951 and we're left with 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Moving on to step 9:
887 can be fit into 5160 5 times, resulting in a remainder of 725.
The next digit of our result is 5. 
Result so far: 111565.5
If we take 4435 away from 5160, we end up with 725.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7250, and continue the process.

On to step 10:
The number 887 fits into 7250 8 times, leaving a remainder of 154.
Put 8 as the next digit of the answer. 
Result so far: 111565.58
Subtract 7096 from 7250 to get 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Advancing to step 11:
The number 887 fits into 1540 1 times, leaving a remainder of 653.
The next digit of our result is 1. 
Result so far: 111565.581
The remainder is 653 after subtracting 887 from 1540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6530, and continue the process.

On to step 12:
887 goes into 6530 7 times with a remainder of 321.
Put 7 as the next digit of the answer. 
Result so far: 111565.5817
The remainder is 321 after subtracting 6209 from 6530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

Moving on to step 13:
The number 887 fits into 3210 3 times, leaving a remainder of 549.
The number 3 becomes the next digit in our result. 
Result so far: 111565.58173
If we take 2661 away from 3210, we end up with 549.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5490, and continue the process.

Step 14:
887 goes into 5490 6 times with a remainder of 168.
The next digit of our result is 6. 
Result so far: 111565.581736
Subtracting 5322 from 5490 leaves us with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Advancing to step 15:
887 can be fit into 1680 1 times, resulting in a remainder of 793.
The next digit of our result is 1. 
Result so far: 111565.5817361
Deduct 887 from 1680 and we're left with 793.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7930, and continue the process.

Let's proceed to step 16:
887 can be fit into 7930 8 times, resulting in a remainder of 834.
The next digit of our result is 8. 
Result so far: 111565.58173618
If we subtract 7096 from 7930, we get 834.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8340, and continue the process.

The final outcome is 111565.58173618, with a leftover of 8.34e-07.
