99055588 ÷ 861 
The aim is to understand the frequency of 861 in 99055588.

Step 1:
The number 861 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 861

Going ahead to step 2:
When dividing 99 by 861, we get 0 with a remainder of 99.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 99 and we're left with 99.
Take the next digit (0) from the dividend and append it to 99, then repeat: 990 / 861

Advancing to step 3:
When dividing 990 by 861, we get 1 with a remainder of 129.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 861 from 990 leaves us with 129.
Append the next digit (5) from the dividend to 129 and continue with: 1295 / 861

Let's proceed to step 4:
When dividing 1295 by 861, we get 1 with a remainder of 434.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtracting 861 from 1295 leaves us with 434.
Append the next digit (5) from the dividend to 434 and continue with: 4345 / 861

Advancing to step 5:
4345 divided by 861 is 5 with a remainder of 40.
The next digit of our result is 5. 
Result so far: 115.0
If we subtract 4305 from 4345, we get 40.
Take the next digit (5) from the dividend and append it to 40, then repeat: 405 / 861

Going ahead to step 6:
861 can be fit into 405 0 times, resulting in a remainder of 405.
The number 0 becomes the next digit in our result. 
Result so far: 1150.0
The remainder is 405 after subtracting 0 from 405.
Grab the next digit (8) from the dividend, add it to 405, then carry on: 4058 / 861

On to step 7:
If we divide 4058 by 861, we get 4 and a remainder of 614.
The next digit of our result is 4. 
Result so far: 11504.0
The remainder is 614 after subtracting 3444 from 4058.
Fetch the next digit (8) from the dividend, attach it to 614 and continue: 6148 / 861

Step 8:
When dividing 6148 by 861, we get 7 with a remainder of 121.
Record the quotient 7 as the next digit in the result. 
Result so far: 115047.0
Deduct 6027 from 6148 and we're left with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

On to step 9:
1210 divided by 861 is 1 with a remainder of 349.
The next digit of our result is 1. 
Result so far: 115047.1
If we subtract 861 from 1210, we get 349.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3490, and continue the process.

Advancing to step 10:
When dividing 3490 by 861, we get 4 with a remainder of 46.
Put 4 as the next digit of the answer. 
Result so far: 115047.14
If we take 3444 away from 3490, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 11:
The number 861 fits into 460 0 times, leaving a remainder of 460.
Put 0 as the next digit of the answer. 
Result so far: 115047.14
Deduct 0 from 460 and we're left with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Step 12:
861 can be fit into 4600 5 times, resulting in a remainder of 295.
Record the quotient 5 as the next digit in the result. 
Result so far: 115047.1405
If we subtract 4305 from 4600, we get 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Let's proceed to step 13:
861 can be fit into 2950 3 times, resulting in a remainder of 367.
Write down 3 as next digit of the result. 
Result so far: 115047.14053
Subtract 2583 from 2950 to get 367.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3670, and continue the process.

Let's proceed to step 14:
When dividing 3670 by 861, we get 4 with a remainder of 226.
Write down 4 as next digit of the result. 
Result so far: 115047.140534
Subtracting 3444 from 3670 leaves us with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Step 15:
861 goes into 2260 2 times with a remainder of 538.
The next digit of our result is 2. 
Result so far: 115047.1405342
The remainder is 538 after subtracting 1722 from 2260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5380, and continue the process.

Moving on to step 16:
The number 861 fits into 5380 6 times, leaving a remainder of 214.
Put 6 as the next digit of the answer. 
Result so far: 115047.14053426
If we take 5166 away from 5380, we end up with 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

The final outcome is 115047.14053426, with a leftover of 2.14e-07.
