We look at the division of 89941386 by 837 
The aim is to understand the frequency of 837 in 89941386.

Let's proceed to step 1:
8 divided by 837 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 837

Moving on to step 2:
The number 837 fits into 89 0 times, leaving a remainder of 89.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 89, we get 89.
Grab the next digit (9) from the dividend, add it to 89, then carry on: 899 / 837

On to step 3:
899 divided by 837 is 1 with a remainder of 62.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 837 from 899 leaves us with 62.
Take the next digit (4) from the dividend and append it to 62, then repeat: 624 / 837

On to step 4:
When dividing 624 by 837, we get 0 with a remainder of 624.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we subtract 0 from 624, we get 624.
Take the next digit (1) from the dividend and append it to 624, then repeat: 6241 / 837

Advancing to step 5:
837 can be fit into 6241 7 times, resulting in a remainder of 382.
Use 7 as the next digit of our solution. 
Result so far: 107.0
Deduct 5859 from 6241 and we're left with 382.
Grab the next digit (3) from the dividend, add it to 382, then carry on: 3823 / 837

Step 6:
The number 837 fits into 3823 4 times, leaving a remainder of 475.
Put 4 as the next digit of the answer. 
Result so far: 1074.0
Subtracting 3348 from 3823 leaves us with 475.
Bring next digit (8) of the dividend behind the 475 and repeat the process: 4758 / 837

Going ahead to step 7:
4758 divided by 837 is 5 with a remainder of 573.
Use 5 as the next digit of our solution. 
Result so far: 10745.0
Subtracting 4185 from 4758 leaves us with 573.
Grab the next digit (6) from the dividend, add it to 573, then carry on: 5736 / 837

Let's proceed to step 8:
837 can be fit into 5736 6 times, resulting in a remainder of 714.
Use 6 as the next digit of our solution. 
Result so far: 107456.0
If we subtract 5022 from 5736, we get 714.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7140, and continue the process.

Advancing to step 9:
837 goes into 7140 8 times with a remainder of 444.
Use 8 as the next digit of our solution. 
Result so far: 107456.8
If we take 6696 away from 7140, we end up with 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Moving on to step 10:
If we divide 4440 by 837, we get 5 and a remainder of 255.
Put 5 as the next digit of the answer. 
Result so far: 107456.85
The remainder is 255 after subtracting 4185 from 4440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Let's proceed to step 11:
837 can be fit into 2550 3 times, resulting in a remainder of 39.
The next digit of our result is 3. 
Result so far: 107456.853
Subtracting 2511 from 2550 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 12:
390 divided by 837 is 0 with a remainder of 390.
Use 0 as the next digit of our solution. 
Result so far: 107456.853
The remainder is 390 after subtracting 0 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Moving on to step 13:
837 can be fit into 3900 4 times, resulting in a remainder of 552.
Use 4 as the next digit of our solution. 
Result so far: 107456.85304
Subtracting 3348 from 3900 leaves us with 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

Going ahead to step 14:
The number 837 fits into 5520 6 times, leaving a remainder of 498.
Use 6 as the next digit of our solution. 
Result so far: 107456.853046
Deduct 5022 from 5520 and we're left with 498.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4980, and continue the process.

On to step 15:
If we divide 4980 by 837, we get 5 and a remainder of 795.
Record the quotient 5 as the next digit in the result. 
Result so far: 107456.8530465
The remainder is 795 after subtracting 4185 from 4980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7950, and continue the process.

Step 16:
7950 divided by 837 is 9 with a remainder of 417.
Use 9 as the next digit of our solution. 
Result so far: 107456.85304659
Deduct 7533 from 7950 and we're left with 417.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4170, and continue the process.

The final result is 107456.85304659 with a remainder of 4.17e-07.
