We divide 83431603 by 861
The aim is to understand the frequency of 861 in 83431603.

Step 1:
The number 861 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 861

On to step 2:
861 can be fit into 83 0 times, resulting in a remainder of 83.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 83 leaves us with 83.
Fetch the next digit (4) from the dividend, attach it to 83 and continue: 834 / 861

Step 3:
When dividing 834 by 861, we get 0 with a remainder of 834.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 834, we get 834.
Grab the next digit (3) from the dividend, add it to 834, then carry on: 8343 / 861

Advancing to step 4:
If we divide 8343 by 861, we get 9 and a remainder of 594.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we subtract 7749 from 8343, we get 594.
Take the next digit (1) from the dividend and append it to 594, then repeat: 5941 / 861

Advancing to step 5:
If we divide 5941 by 861, we get 6 and a remainder of 775.
Record the quotient 6 as the next digit in the result. 
Result so far: 96.0
The remainder is 775 after subtracting 5166 from 5941.
Take the next digit (6) from the dividend and append it to 775, then repeat: 7756 / 861

Let's proceed to step 6:
7756 divided by 861 is 9 with a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 969.0
If we subtract 7749 from 7756, we get 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 861

Going ahead to step 7:
If we divide 70 by 861, we get 0 and a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 9690.0
The remainder is 70 after subtracting 0 from 70.
Grab the next digit (3) from the dividend, add it to 70, then carry on: 703 / 861

Step 8:
If we divide 703 by 861, we get 0 and a remainder of 703.
Record the quotient 0 as the next digit in the result. 
Result so far: 96900.0
Subtract 0 from 703 to get 703.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7030, and continue the process.

On to step 9:
861 goes into 7030 8 times with a remainder of 142.
Record the quotient 8 as the next digit in the result. 
Result so far: 96900.8
The remainder is 142 after subtracting 6888 from 7030.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Moving on to step 10:
861 can be fit into 1420 1 times, resulting in a remainder of 559.
The next digit of our result is 1. 
Result so far: 96900.81
Subtracting 861 from 1420 leaves us with 559.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5590, and continue the process.

Advancing to step 11:
The number 861 fits into 5590 6 times, leaving a remainder of 424.
The number 6 becomes the next digit in our result. 
Result so far: 96900.816
Subtract 5166 from 5590 to get 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

On to step 12:
4240 divided by 861 is 4 with a remainder of 796.
Use 4 as the next digit of our solution. 
Result so far: 96900.8164
The remainder is 796 after subtracting 3444 from 4240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7960, and continue the process.

Step 13:
When dividing 7960 by 861, we get 9 with a remainder of 211.
The next digit of our result is 9. 
Result so far: 96900.81649
If we subtract 7749 from 7960, we get 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Let's proceed to step 14:
The number 861 fits into 2110 2 times, leaving a remainder of 388.
Write down 2 as next digit of the result. 
Result so far: 96900.816492
If we take 1722 away from 2110, we end up with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Moving on to step 15:
If we divide 3880 by 861, we get 4 and a remainder of 436.
The next digit of our result is 4. 
Result so far: 96900.8164924
The remainder is 436 after subtracting 3444 from 3880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

Let's proceed to step 16:
4360 divided by 861 is 5 with a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 96900.81649245
Subtracting 4305 from 4360 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

The final result is 96900.81649245 with a remainder of 5.5e-08.
