19651975 divided by 898 
The aim is to understand the frequency of 898 in 19651975.

Advancing to step 1:
If we divide 1 by 898, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 898

On to step 2:
When dividing 19 by 898, we get 0 with a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 19, we end up with 19.
Append the next digit (6) from the dividend to 19 and continue with: 196 / 898

On to step 3:
898 goes into 196 0 times with a remainder of 196.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 196 and we're left with 196.
Include the next digit (5) from the dividend after 196, then repeat: 1965 / 898

Going ahead to step 4:
1965 divided by 898 is 2 with a remainder of 169.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 1796 from 1965 and we're left with 169.
Append the next digit (1) from the dividend to 169 and continue with: 1691 / 898

Moving on to step 5:
The number 898 fits into 1691 1 times, leaving a remainder of 793.
Put 1 as the next digit of the answer. 
Result so far: 21.0
Subtracting 898 from 1691 leaves us with 793.
Append the next digit (9) from the dividend to 793 and continue with: 7939 / 898

Let's proceed to step 6:
7939 divided by 898 is 8 with a remainder of 755.
The next digit of our result is 8. 
Result so far: 218.0
If we take 7184 away from 7939, we end up with 755.
Bring next digit (7) of the dividend behind the 755 and repeat the process: 7557 / 898

Step 7:
7557 divided by 898 is 8 with a remainder of 373.
The next digit of our result is 8. 
Result so far: 2188.0
If we subtract 7184 from 7557, we get 373.
Append the next digit (5) from the dividend to 373 and continue with: 3735 / 898

Advancing to step 8:
898 can be fit into 3735 4 times, resulting in a remainder of 143.
The number 4 becomes the next digit in our result. 
Result so far: 21884.0
Deduct 3592 from 3735 and we're left with 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Advancing to step 9:
The number 898 fits into 1430 1 times, leaving a remainder of 532.
The next digit of our result is 1. 
Result so far: 21884.1
If we subtract 898 from 1430, we get 532.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

Advancing to step 10:
If we divide 5320 by 898, we get 5 and a remainder of 830.
The number 5 becomes the next digit in our result. 
Result so far: 21884.15
The remainder is 830 after subtracting 4490 from 5320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8300, and continue the process.

Going ahead to step 11:
898 can be fit into 8300 9 times, resulting in a remainder of 218.
Use 9 as the next digit of our solution. 
Result so far: 21884.159
If we subtract 8082 from 8300, we get 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Advancing to step 12:
The number 898 fits into 2180 2 times, leaving a remainder of 384.
Use 2 as the next digit of our solution. 
Result so far: 21884.1592
Subtract 1796 from 2180 to get 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Advancing to step 13:
If we divide 3840 by 898, we get 4 and a remainder of 248.
Record the quotient 4 as the next digit in the result. 
Result so far: 21884.15924
If we subtract 3592 from 3840, we get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Moving on to step 14:
898 can be fit into 2480 2 times, resulting in a remainder of 684.
Write down 2 as next digit of the result. 
Result so far: 21884.159242
Subtracting 1796 from 2480 leaves us with 684.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6840, and continue the process.

Let's proceed to step 15:
When dividing 6840 by 898, we get 7 with a remainder of 554.
Use 7 as the next digit of our solution. 
Result so far: 21884.1592427
If we take 6286 away from 6840, we end up with 554.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5540, and continue the process.

Advancing to step 16:
898 goes into 5540 6 times with a remainder of 152.
Put 6 as the next digit of the answer. 
Result so far: 21884.15924276
Subtracting 5388 from 5540 leaves us with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

After the division, we end up with 21884.15924276 and a remainder of 1.52e-07.
