51151231 ÷ 894 
The aim is to understand the frequency of 894 in 51151231.

On to step 1:
894 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 894

Let's proceed to step 2:
894 goes into 51 0 times with a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Fetch the next digit (1) from the dividend, attach it to 51 and continue: 511 / 894

Advancing to step 3:
If we divide 511 by 894, we get 0 and a remainder of 511.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 511 to get 511.
Take the next digit (5) from the dividend and append it to 511, then repeat: 5115 / 894

Moving on to step 4:
894 can be fit into 5115 5 times, resulting in a remainder of 645.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtracting 4470 from 5115 leaves us with 645.
Append the next digit (1) from the dividend to 645 and continue with: 6451 / 894

Let's proceed to step 5:
When dividing 6451 by 894, we get 7 with a remainder of 193.
Put 7 as the next digit of the answer. 
Result so far: 57.0
If we subtract 6258 from 6451, we get 193.
Append the next digit (2) from the dividend to 193 and continue with: 1932 / 894

Moving on to step 6:
If we divide 1932 by 894, we get 2 and a remainder of 144.
Record the quotient 2 as the next digit in the result. 
Result so far: 572.0
Deduct 1788 from 1932 and we're left with 144.
Grab the next digit (3) from the dividend, add it to 144, then carry on: 1443 / 894

Step 7:
894 can be fit into 1443 1 times, resulting in a remainder of 549.
The number 1 becomes the next digit in our result. 
Result so far: 5721.0
Deduct 894 from 1443 and we're left with 549.
Bring next digit (1) of the dividend behind the 549 and repeat the process: 5491 / 894

Moving on to step 8:
894 can be fit into 5491 6 times, resulting in a remainder of 127.
Use 6 as the next digit of our solution. 
Result so far: 57216.0
If we subtract 5364 from 5491, we get 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Moving on to step 9:
When dividing 1270 by 894, we get 1 with a remainder of 376.
Use 1 as the next digit of our solution. 
Result so far: 57216.1
If we subtract 894 from 1270, we get 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Going ahead to step 10:
3760 divided by 894 is 4 with a remainder of 184.
The next digit of our result is 4. 
Result so far: 57216.14
Subtracting 3576 from 3760 leaves us with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Moving on to step 11:
If we divide 1840 by 894, we get 2 and a remainder of 52.
Put 2 as the next digit of the answer. 
Result so far: 57216.142
Subtracting 1788 from 1840 leaves us 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.

Let's proceed to step 12:
If we divide 520 by 894, we get 0 and a remainder of 520.
The next digit of our result is 0. 
Result so far: 57216.142
Deduct 0 from 520 and we're left with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Advancing to step 13:
When dividing 5200 by 894, we get 5 with a remainder of 730.
Write down 5 as next digit of the result. 
Result so far: 57216.14205
Subtract 4470 from 5200 to get 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7300, and continue the process.

Step 14:
7300 divided by 894 is 8 with a remainder of 148.
Record the quotient 8 as the next digit in the result. 
Result so far: 57216.142058
Deduct 7152 from 7300 and we're left with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Advancing to step 15:
1480 divided by 894 is 1 with a remainder of 586.
The number 1 becomes the next digit in our result. 
Result so far: 57216.1420581
Subtract 894 from 1480 to get 586.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5860, and continue the process.

On to step 16:
When dividing 5860 by 894, we get 6 with a remainder of 496.
Record the quotient 6 as the next digit in the result. 
Result so far: 57216.14205816
If we subtract 5364 from 5860, we get 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Our division results in 57216.14205816 with a remaining 4.96e-07.
