90774048 ÷ 837 
The aim is to understand the frequency of 837 in 90774048.

Going ahead to step 1:
When dividing 9 by 837, we get 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 837

Step 2:
The number 837 fits into 90 0 times, leaving a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 90 and we're left with 90.
Take the next digit (7) from the dividend and append it to 90, then repeat: 907 / 837

Going ahead to step 3:
837 goes into 907 1 times with a remainder of 70.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 837 from 907 and we're left with 70.
Bring next digit (7) of the dividend behind the 70 and repeat the process: 707 / 837

Let's proceed to step 4:
If we divide 707 by 837, we get 0 and a remainder of 707.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtracting 0 from 707 leaves us with 707.
Take the next digit (4) from the dividend and append it to 707, then repeat: 7074 / 837

On to step 5:
If we divide 7074 by 837, we get 8 and a remainder of 378.
Record the quotient 8 as the next digit in the result. 
Result so far: 108.0
Subtract 6696 from 7074 to get 378.
Grab the next digit (0) from the dividend, add it to 378, then carry on: 3780 / 837

Going ahead to step 6:
The number 837 fits into 3780 4 times, leaving a remainder of 432.
Put 4 as the next digit of the answer. 
Result so far: 1084.0
The remainder is 432 after subtracting 3348 from 3780.
Fetch the next digit (4) from the dividend, attach it to 432 and continue: 4324 / 837

Step 7:
If we divide 4324 by 837, we get 5 and a remainder of 139.
Write down 5 as next digit of the result. 
Result so far: 10845.0
If we subtract 4185 from 4324, we get 139.
Grab the next digit (8) from the dividend, add it to 139, then carry on: 1398 / 837

Going ahead to step 8:
If we divide 1398 by 837, we get 1 and a remainder of 561.
Record the quotient 1 as the next digit in the result. 
Result so far: 108451.0
Subtracting 837 from 1398 leaves us with 561.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5610, and continue the process.

Going ahead to step 9:
When dividing 5610 by 837, we get 6 with a remainder of 588.
Write down 6 as next digit of the result. 
Result so far: 108451.6
Deduct 5022 from 5610 and we're left with 588.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5880, and continue the process.

On to step 10:
If we divide 5880 by 837, we get 7 and a remainder of 21.
Record the quotient 7 as the next digit in the result. 
Result so far: 108451.67
If we subtract 5859 from 5880, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 11:
The number 837 fits into 210 0 times, leaving a remainder of 210.
The number 0 becomes the next digit in our result. 
Result so far: 108451.67
Subtracting 0 from 210 leaves us with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Let's proceed to step 12:
837 can be fit into 2100 2 times, resulting in a remainder of 426.
Use 2 as the next digit of our solution. 
Result so far: 108451.6702
Subtracting 1674 from 2100 leaves us with 426.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4260, and continue the process.

Going ahead to step 13:
4260 divided by 837 is 5 with a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 108451.67025
Subtracting 4185 from 4260 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 14:
If we divide 750 by 837, we get 0 and a remainder of 750.
Use 0 as the next digit of our solution. 
Result so far: 108451.67025
The remainder is 750 after subtracting 0 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

Step 15:
837 goes into 7500 8 times with a remainder of 804.
Put 8 as the next digit of the answer. 
Result so far: 108451.6702508
Subtracting 6696 from 7500 leaves us with 804.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8040, and continue the process.

Going ahead to step 16:
837 can be fit into 8040 9 times, resulting in a remainder of 507.
The number 9 becomes the next digit in our result. 
Result so far: 108451.67025089
The remainder is 507 after subtracting 7533 from 8040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5070, and continue the process.

In conclusion, the division gives 108451.67025089 with a balance of 5.07e-07.
