We're dividing 37790216 by 861 
The aim is to understand the frequency of 861 in 37790216.

Going ahead to step 1:
When dividing 3 by 861, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 861

Let's proceed to step 2:
37 divided by 861 is 0 with a remainder of 37.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 37 after subtracting 0 from 37.
Bring next digit (7) of the dividend behind the 37 and repeat the process: 377 / 861

Going ahead to step 3:
861 goes into 377 0 times with a remainder of 377.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 377 leaves us with 377.
Take the next digit (9) from the dividend and append it to 377, then repeat: 3779 / 861

Advancing to step 4:
The number 861 fits into 3779 4 times, leaving a remainder of 335.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 3444 from 3779 and we're left with 335.
Bring next digit (0) of the dividend behind the 335 and repeat the process: 3350 / 861

Step 5:
When dividing 3350 by 861, we get 3 with a remainder of 767.
Use 3 as the next digit of our solution. 
Result so far: 43.0
The remainder is 767 after subtracting 2583 from 3350.
Grab the next digit (2) from the dividend, add it to 767, then carry on: 7672 / 861

Let's proceed to step 6:
861 can be fit into 7672 8 times, resulting in a remainder of 784.
Put 8 as the next digit of the answer. 
Result so far: 438.0
If we subtract 6888 from 7672, we get 784.
Append the next digit (1) from the dividend to 784 and continue with: 7841 / 861

Let's proceed to step 7:
7841 divided by 861 is 9 with a remainder of 92.
Use 9 as the next digit of our solution. 
Result so far: 4389.0
Deduct 7749 from 7841 and we're left with 92.
Include the next digit (6) from the dividend after 92, then repeat: 926 / 861

Let's proceed to step 8:
The number 861 fits into 926 1 times, leaving a remainder of 65.
Put 1 as the next digit of the answer. 
Result so far: 43891.0
If we take 861 away from 926, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Step 9:
When dividing 650 by 861, we get 0 with a remainder of 650.
Use 0 as the next digit of our solution. 
Result so far: 43891.0
Subtracting 0 from 650 leaves us with 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Step 10:
6500 divided by 861 is 7 with a remainder of 473.
Record the quotient 7 as the next digit in the result. 
Result so far: 43891.07
If we take 6027 away from 6500, we end up with 473.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4730, and continue the process.

Let's proceed to step 11:
861 goes into 4730 5 times with a remainder of 425.
Put 5 as the next digit of the answer. 
Result so far: 43891.075
Subtract 4305 from 4730 to get 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Going ahead to step 12:
861 goes into 4250 4 times with a remainder of 806.
Use 4 as the next digit of our solution. 
Result so far: 43891.0754
Subtract 3444 from 4250 to get 806.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8060, and continue the process.

Advancing to step 13:
861 goes into 8060 9 times with a remainder of 311.
Put 9 as the next digit of the answer. 
Result so far: 43891.07549
If we subtract 7749 from 8060, we get 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

Advancing to step 14:
If we divide 3110 by 861, we get 3 and a remainder of 527.
The number 3 becomes the next digit in our result. 
Result so far: 43891.075493
The remainder is 527 after subtracting 2583 from 3110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5270, and continue the process.

Let's proceed to step 15:
5270 divided by 861 is 6 with a remainder of 104.
Use 6 as the next digit of our solution. 
Result so far: 43891.0754936
Subtracting 5166 from 5270 leaves us with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Step 16:
861 can be fit into 1040 1 times, resulting in a remainder of 179.
Use 1 as the next digit of our solution. 
Result so far: 43891.07549361
The remainder is 179 after subtracting 861 from 1040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Our division results in 43891.07549361 with a remaining 1.79e-07.
