We're dividing 49720777 by 861 
The aim is to understand the frequency of 861 in 49720777.

Step 1:
When dividing 4 by 861, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 861

On to step 2:
If we divide 49 by 861, we get 0 and a remainder of 49.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 49, we end up with 49.
Append the next digit (7) from the dividend to 49 and continue with: 497 / 861

Let's proceed to step 3:
If we divide 497 by 861, we get 0 and a remainder of 497.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 497, we end up with 497.
Bring next digit (2) of the dividend behind the 497 and repeat the process: 4972 / 861

Let's proceed to step 4:
4972 divided by 861 is 5 with a remainder of 667.
Write down 5 as next digit of the result. 
Result so far: 5.0
Deduct 4305 from 4972 and we're left with 667.
Grab the next digit (0) from the dividend, add it to 667, then carry on: 6670 / 861

On to step 5:
If we divide 6670 by 861, we get 7 and a remainder of 643.
Use 7 as the next digit of our solution. 
Result so far: 57.0
If we take 6027 away from 6670, we end up with 643.
Take the next digit (7) from the dividend and append it to 643, then repeat: 6437 / 861

Step 6:
When dividing 6437 by 861, we get 7 with a remainder of 410.
The number 7 becomes the next digit in our result. 
Result so far: 577.0
If we take 6027 away from 6437, we end up with 410.
Grab the next digit (7) from the dividend, add it to 410, then carry on: 4107 / 861

Going ahead to step 7:
The number 861 fits into 4107 4 times, leaving a remainder of 663.
Write down 4 as next digit of the result. 
Result so far: 5774.0
Subtract 3444 from 4107 to get 663.
Take the next digit (7) from the dividend and append it to 663, then repeat: 6637 / 861

Going ahead to step 8:
861 goes into 6637 7 times with a remainder of 610.
The number 7 becomes the next digit in our result. 
Result so far: 57747.0
Subtract 6027 from 6637 to get 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Advancing to step 9:
The number 861 fits into 6100 7 times, leaving a remainder of 73.
Use 7 as the next digit of our solution. 
Result so far: 57747.7
Deduct 6027 from 6100 and we're left with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Advancing to step 10:
The number 861 fits into 730 0 times, leaving a remainder of 730.
Record the quotient 0 as the next digit in the result. 
Result so far: 57747.7
Subtracting 0 from 730 leaves us with 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7300, and continue the process.

Going ahead to step 11:
When dividing 7300 by 861, we get 8 with a remainder of 412.
Record the quotient 8 as the next digit in the result. 
Result so far: 57747.708
Deduct 6888 from 7300 and we're left with 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

On to step 12:
If we divide 4120 by 861, we get 4 and a remainder of 676.
Record the quotient 4 as the next digit in the result. 
Result so far: 57747.7084
Deduct 3444 from 4120 and we're left with 676.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6760, and continue the process.

Let's proceed to step 13:
861 can be fit into 6760 7 times, resulting in a remainder of 733.
Record the quotient 7 as the next digit in the result. 
Result so far: 57747.70847
Deduct 6027 from 6760 and we're left with 733.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7330, and continue the process.

On to step 14:
If we divide 7330 by 861, we get 8 and a remainder of 442.
Put 8 as the next digit of the answer. 
Result so far: 57747.708478
If we take 6888 away from 7330, we end up with 442.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

Let's proceed to step 15:
861 can be fit into 4420 5 times, resulting in a remainder of 115.
Put 5 as the next digit of the answer. 
Result so far: 57747.7084785
The remainder is 115 after subtracting 4305 from 4420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Advancing to step 16:
The number 861 fits into 1150 1 times, leaving a remainder of 289.
Write down 1 as next digit of the result. 
Result so far: 57747.70847851
If we subtract 861 from 1150, we get 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

Our division results in 57747.70847851 with a remaining 2.89e-07.
