91238698 divided by 837 
The aim is to understand the frequency of 837 in 91238698.

Step 1:
The number 837 fits into 9 0 times, leaving a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 837

Going ahead to step 2:
When dividing 91 by 837, we get 0 with a remainder of 91.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 91, we end up with 91.
Take the next digit (2) from the dividend and append it to 91, then repeat: 912 / 837

Step 3:
If we divide 912 by 837, we get 1 and a remainder of 75.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 837 from 912 leaves us with 75.
Include the next digit (3) from the dividend after 75, then repeat: 753 / 837

Step 4:
837 goes into 753 0 times with a remainder of 753.
Write down 0 as next digit of the result. 
Result so far: 10.0
Deduct 0 from 753 and we're left with 753.
Fetch the next digit (8) from the dividend, attach it to 753 and continue: 7538 / 837

Let's proceed to step 5:
837 goes into 7538 9 times with a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 109.0
Deduct 7533 from 7538 and we're left with 5.
Take the next digit (6) from the dividend and append it to 5, then repeat: 56 / 837

Advancing to step 6:
The number 837 fits into 56 0 times, leaving a remainder of 56.
Use 0 as the next digit of our solution. 
Result so far: 1090.0
The remainder is 56 after subtracting 0 from 56.
Bring next digit (9) of the dividend behind the 56 and repeat the process: 569 / 837

Let's proceed to step 7:
When dividing 569 by 837, we get 0 with a remainder of 569.
The next digit of our result is 0. 
Result so far: 10900.0
Subtract 0 from 569 to get 569.
Fetch the next digit (8) from the dividend, attach it to 569 and continue: 5698 / 837

Moving on to step 8:
837 goes into 5698 6 times with a remainder of 676.
The number 6 becomes the next digit in our result. 
Result so far: 109006.0
Deduct 5022 from 5698 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.

Going ahead to step 9:
When dividing 6760 by 837, we get 8 with a remainder of 64.
The next digit of our result is 8. 
Result so far: 109006.8
If we subtract 6696 from 6760, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 10:
When dividing 640 by 837, we get 0 with a remainder of 640.
Put 0 as the next digit of the answer. 
Result so far: 109006.8
If we take 0 away from 640, we end up with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

On to step 11:
The number 837 fits into 6400 7 times, leaving a remainder of 541.
Write down 7 as next digit of the result. 
Result so far: 109006.807
If we subtract 5859 from 6400, we get 541.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5410, and continue the process.

Step 12:
837 can be fit into 5410 6 times, resulting in a remainder of 388.
Use 6 as the next digit of our solution. 
Result so far: 109006.8076
If we take 5022 away from 5410, 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.

Advancing to step 13:
The number 837 fits into 3880 4 times, leaving a remainder of 532.
The next digit of our result is 4. 
Result so far: 109006.80764
If we take 3348 away from 3880, we end up with 532.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

Going ahead to step 14:
837 can be fit into 5320 6 times, resulting in a remainder of 298.
Write down 6 as next digit of the result. 
Result so far: 109006.807646
Subtract 5022 from 5320 to get 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

On to step 15:
The number 837 fits into 2980 3 times, leaving a remainder of 469.
The number 3 becomes the next digit in our result. 
Result so far: 109006.8076463
If we take 2511 away from 2980, we end up with 469.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4690, and continue the process.

Let's proceed to step 16:
837 goes into 4690 5 times with a remainder of 505.
Put 5 as the next digit of the answer. 
Result so far: 109006.80764635
The remainder is 505 after subtracting 4185 from 4690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

The quotient of the division is 109006.80764635, and the remainder is 5.05e-07.
