1686196 ÷ 901 
The aim is to understand the frequency of 901 in 1686196.

Moving on to step 1:
901 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 901

Advancing to step 2:
901 can be fit into 16 0 times, resulting in a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 16 to get 16.
Fetch the next digit (8) from the dividend, attach it to 16 and continue: 168 / 901

Let's proceed to step 3:
168 divided by 901 is 0 with a remainder of 168.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 168, we end up with 168.
Append the next digit (6) from the dividend to 168 and continue with: 1686 / 901

Let's proceed to step 4:
1686 divided by 901 is 1 with a remainder of 785.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 901 from 1686 and we're left with 785.
Include the next digit (1) from the dividend after 785, then repeat: 7851 / 901

On to step 5:
7851 divided by 901 is 8 with a remainder of 643.
The next digit of our result is 8. 
Result so far: 18.0
If we subtract 7208 from 7851, we get 643.
Append the next digit (9) from the dividend to 643 and continue with: 6439 / 901

Advancing to step 6:
901 goes into 6439 7 times with a remainder of 132.
Put 7 as the next digit of the answer. 
Result so far: 187.0
The remainder is 132 after subtracting 6307 from 6439.
Append the next digit (6) from the dividend to 132 and continue with: 1326 / 901

On to step 7:
901 can be fit into 1326 1 times, resulting in a remainder of 425.
The next digit of our result is 1. 
Result so far: 1871.0
The remainder is 425 after subtracting 901 from 1326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Advancing to step 8:
When dividing 4250 by 901, we get 4 with a remainder of 646.
Write down 4 as next digit of the result. 
Result so far: 1871.4
The remainder is 646 after subtracting 3604 from 4250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6460, and continue the process.

Advancing to step 9:
901 goes into 6460 7 times with a remainder of 153.
Put 7 as the next digit of the answer. 
Result so far: 1871.47
The remainder is 153 after subtracting 6307 from 6460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

On to step 10:
When dividing 1530 by 901, we get 1 with a remainder of 629.
Put 1 as the next digit of the answer. 
Result so far: 1871.471
If we subtract 901 from 1530, we get 629.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6290, and continue the process.

Step 11:
If we divide 6290 by 901, we get 6 and a remainder of 884.
The number 6 becomes the next digit in our result. 
Result so far: 1871.4716
Subtract 5406 from 6290 to get 884.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8840, and continue the process.

Let's proceed to step 12:
901 goes into 8840 9 times with a remainder of 731.
The next digit of our result is 9. 
Result so far: 1871.47169
If we take 8109 away from 8840, we end up with 731.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7310, and continue the process.

Advancing to step 13:
The number 901 fits into 7310 8 times, leaving a remainder of 102.
Record the quotient 8 as the next digit in the result. 
Result so far: 1871.471698
If we take 7208 away from 7310, we end up with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Step 14:
901 can be fit into 1020 1 times, resulting in a remainder of 119.
Write down 1 as next digit of the result. 
Result so far: 1871.4716981
Subtract 901 from 1020 to get 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Advancing to step 15:
The number 901 fits into 1190 1 times, leaving a remainder of 289.
Record the quotient 1 as the next digit in the result. 
Result so far: 1871.47169811
Deduct 901 from 1190 and we're left with 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 1871.47169811 with a remaining 2.89e-07.
