89537030 ÷ 851 
The aim is to understand the frequency of 851 in 89537030.

On to step 1:
8 divided by 851 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 851

Step 2:
851 goes into 89 0 times with a remainder of 89.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 89, we end up with 89.
Take the next digit (5) from the dividend and append it to 89, then repeat: 895 / 851

Going ahead to step 3:
895 divided by 851 is 1 with a remainder of 44.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 44 after subtracting 851 from 895.
Include the next digit (3) from the dividend after 44, then repeat: 443 / 851

Moving on to step 4:
When dividing 443 by 851, we get 0 with a remainder of 443.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Deduct 0 from 443 and we're left with 443.
Bring next digit (7) of the dividend behind the 443 and repeat the process: 4437 / 851

Moving on to step 5:
The number 851 fits into 4437 5 times, leaving a remainder of 182.
Use 5 as the next digit of our solution. 
Result so far: 105.0
Deduct 4255 from 4437 and we're left with 182.
Include the next digit (0) from the dividend after 182, then repeat: 1820 / 851

Going ahead to step 6:
851 can be fit into 1820 2 times, resulting in a remainder of 118.
Write down 2 as next digit of the result. 
Result so far: 1052.0
Deduct 1702 from 1820 and we're left with 118.
Bring next digit (3) of the dividend behind the 118 and repeat the process: 1183 / 851

On to step 7:
The number 851 fits into 1183 1 times, leaving a remainder of 332.
Use 1 as the next digit of our solution. 
Result so far: 10521.0
If we subtract 851 from 1183, we get 332.
Grab the next digit (0) from the dividend, add it to 332, then carry on: 3320 / 851

Advancing to step 8:
851 goes into 3320 3 times with a remainder of 767.
Record the quotient 3 as the next digit in the result. 
Result so far: 105213.0
Subtracting 2553 from 3320 leaves us with 767.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7670, and continue the process.

On to step 9:
When dividing 7670 by 851, we get 9 with a remainder of 11.
The next digit of our result is 9. 
Result so far: 105213.9
Deduct 7659 from 7670 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 10:
110 divided by 851 is 0 with a remainder of 110.
The number 0 becomes the next digit in our result. 
Result so far: 105213.9
Deduct 0 from 110 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Moving on to step 11:
851 goes into 1100 1 times with a remainder of 249.
Write down 1 as next digit of the result. 
Result so far: 105213.901
If we take 851 away from 1100, we end up with 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

On to step 12:
851 can be fit into 2490 2 times, resulting in a remainder of 788.
Use 2 as the next digit of our solution. 
Result so far: 105213.9012
If we subtract 1702 from 2490, we get 788.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7880, and continue the process.

On to step 13:
If we divide 7880 by 851, we get 9 and a remainder of 221.
Put 9 as the next digit of the answer. 
Result so far: 105213.90129
Subtracting 7659 from 7880 leaves us with 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

Going ahead to step 14:
The number 851 fits into 2210 2 times, leaving a remainder of 508.
Record the quotient 2 as the next digit in the result. 
Result so far: 105213.901292
Subtracting 1702 from 2210 leaves us with 508.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

Step 15:
The number 851 fits into 5080 5 times, leaving a remainder of 825.
Write down 5 as next digit of the result. 
Result so far: 105213.9012925
If we subtract 4255 from 5080, we get 825.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8250, and continue the process.

Step 16:
851 goes into 8250 9 times with a remainder of 591.
Write down 9 as next digit of the result. 
Result so far: 105213.90129259
Deduct 7659 from 8250 and we're left with 591.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5910, and continue the process.

Our division results in 105213.90129259 with a remaining 5.91e-07.
