We look at the division of 837573 by 89 
The aim is to understand the frequency of 89 in 837573.

Going ahead to step 1:
The number 89 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 89

Advancing to step 2:
If we divide 83 by 89, we get 0 and a remainder of 83.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 83 and we're left with 83.
Bring next digit (7) of the dividend behind the 83 and repeat the process: 837 / 89

Moving on to step 3:
89 goes into 837 9 times with a remainder of 36.
The next digit of our result is 9. 
Result so far: 9.0
If we take 801 away from 837, we end up with 36.
Append the next digit (5) from the dividend to 36 and continue with: 365 / 89

Advancing to step 4:
89 can be fit into 365 4 times, resulting in a remainder of 9.
The number 4 becomes the next digit in our result. 
Result so far: 94.0
Deduct 356 from 365 and we're left with 9.
Fetch the next digit (7) from the dividend, attach it to 9 and continue: 97 / 89

Moving on to step 5:
The number 89 fits into 97 1 times, leaving a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 941.0
Deduct 89 from 97 and we're left with 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 89

Moving on to step 6:
83 divided by 89 is 0 with a remainder of 83.
The number 0 becomes the next digit in our result. 
Result so far: 9410.0
Subtract 0 from 83 to get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Moving on to step 7:
If we divide 830 by 89, we get 9 and a remainder of 29.
Write down 9 as next digit of the result. 
Result so far: 9410.9
If we subtract 801 from 830, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 8:
When dividing 290 by 89, we get 3 with a remainder of 23.
Put 3 as the next digit of the answer. 
Result so far: 9410.93
Subtract 267 from 290 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 9:
89 can be fit into 230 2 times, resulting in a remainder of 52.
Write down 2 as next digit of the result. 
Result so far: 9410.932
Deduct 178 from 230 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 10:
The number 89 fits into 520 5 times, leaving a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 9410.9325
Subtracting 445 from 520 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.

Moving on to step 11:
If we divide 750 by 89, we get 8 and a remainder of 38.
The next digit of our result is 8. 
Result so far: 9410.93258
Deduct 712 from 750 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 12:
If we divide 380 by 89, we get 4 and a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 9410.932584
Deduct 356 from 380 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 13:
If we divide 240 by 89, we get 2 and a remainder of 62.
Use 2 as the next digit of our solution. 
Result so far: 9410.9325842
Deduct 178 from 240 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 14:
If we divide 620 by 89, we get 6 and a remainder of 86.
Put 6 as the next digit of the answer. 
Result so far: 9410.93258426
If we take 534 away from 620, we end up with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

The quotient of the division is 9410.93258426, and the remainder is 8.6e-08.
