We divide 77641579 by 887
The aim is to understand the frequency of 887 in 77641579.

Step 1:
The number 887 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 887

Going ahead to step 2:
887 goes into 77 0 times with a remainder of 77.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Fetch the next digit (6) from the dividend, attach it to 77 and continue: 776 / 887

Step 3:
887 goes into 776 0 times with a remainder of 776.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 776 after subtracting 0 from 776.
Grab the next digit (4) from the dividend, add it to 776, then carry on: 7764 / 887

On to step 4:
7764 divided by 887 is 8 with a remainder of 668.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Deduct 7096 from 7764 and we're left with 668.
Fetch the next digit (1) from the dividend, attach it to 668 and continue: 6681 / 887

Let's proceed to step 5:
887 can be fit into 6681 7 times, resulting in a remainder of 472.
Write down 7 as next digit of the result. 
Result so far: 87.0
Subtracting 6209 from 6681 leaves us with 472.
Append the next digit (5) from the dividend to 472 and continue with: 4725 / 887

On to step 6:
If we divide 4725 by 887, we get 5 and a remainder of 290.
The next digit of our result is 5. 
Result so far: 875.0
If we subtract 4435 from 4725, we get 290.
Bring next digit (7) of the dividend behind the 290 and repeat the process: 2907 / 887

Let's proceed to step 7:
2907 divided by 887 is 3 with a remainder of 246.
The number 3 becomes the next digit in our result. 
Result so far: 8753.0
If we subtract 2661 from 2907, we get 246.
Bring next digit (9) of the dividend behind the 246 and repeat the process: 2469 / 887

Moving on to step 8:
887 can be fit into 2469 2 times, resulting in a remainder of 695.
Use 2 as the next digit of our solution. 
Result so far: 87532.0
Deduct 1774 from 2469 and we're left with 695.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6950, and continue the process.

Moving on to step 9:
887 goes into 6950 7 times with a remainder of 741.
Write down 7 as next digit of the result. 
Result so far: 87532.7
Subtract 6209 from 6950 to get 741.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7410, and continue the process.

Step 10:
When dividing 7410 by 887, we get 8 with a remainder of 314.
The number 8 becomes the next digit in our result. 
Result so far: 87532.78
Subtract 7096 from 7410 to get 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Moving on to step 11:
3140 divided by 887 is 3 with a remainder of 479.
Record the quotient 3 as the next digit in the result. 
Result so far: 87532.783
Deduct 2661 from 3140 and we're left with 479.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4790, and continue the process.

On to step 12:
887 goes into 4790 5 times with a remainder of 355.
The next digit of our result is 5. 
Result so far: 87532.7835
Subtract 4435 from 4790 to get 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

Advancing to step 13:
887 can be fit into 3550 4 times, resulting in a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 87532.78354
The remainder is 2 after subtracting 3548 from 3550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 14:
20 divided by 887 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 87532.78354
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 15:
When dividing 200 by 887, we get 0 with a remainder of 200.
The number 0 becomes the next digit in our result. 
Result so far: 87532.78354
Subtract 0 from 200 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The final outcome is 87532.78354, with a leftover of 2e-06.
