15141370 ÷ 891 
The aim is to understand the frequency of 891 in 15141370.

Going ahead to step 1:
891 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 891

Going ahead to step 2:
If we divide 15 by 891, we get 0 and a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Bring next digit (1) of the dividend behind the 15 and repeat the process: 151 / 891

Let's proceed to step 3:
The number 891 fits into 151 0 times, leaving a remainder of 151.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 151 leaves us with 151.
Append the next digit (4) from the dividend to 151 and continue with: 1514 / 891

Going ahead to step 4:
If we divide 1514 by 891, we get 1 and a remainder of 623.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 891 away from 1514, we end up with 623.
Fetch the next digit (1) from the dividend, attach it to 623 and continue: 6231 / 891

On to step 5:
891 goes into 6231 6 times with a remainder of 885.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
Deduct 5346 from 6231 and we're left with 885.
Fetch the next digit (3) from the dividend, attach it to 885 and continue: 8853 / 891

Step 6:
8853 divided by 891 is 9 with a remainder of 834.
Record the quotient 9 as the next digit in the result. 
Result so far: 169.0
The remainder is 834 after subtracting 8019 from 8853.
Fetch the next digit (7) from the dividend, attach it to 834 and continue: 8347 / 891

On to step 7:
If we divide 8347 by 891, we get 9 and a remainder of 328.
Record the quotient 9 as the next digit in the result. 
Result so far: 1699.0
If we take 8019 away from 8347, we end up with 328.
Grab the next digit (0) from the dividend, add it to 328, then carry on: 3280 / 891

Advancing to step 8:
If we divide 3280 by 891, we get 3 and a remainder of 607.
Record the quotient 3 as the next digit in the result. 
Result so far: 16993.0
Subtracting 2673 from 3280 leaves us with 607.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6070, and continue the process.

On to step 9:
When dividing 6070 by 891, we get 6 with a remainder of 724.
The next digit of our result is 6. 
Result so far: 16993.6
Subtracting 5346 from 6070 leaves us with 724.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7240, and continue the process.

Advancing to step 10:
The number 891 fits into 7240 8 times, leaving a remainder of 112.
Use 8 as the next digit of our solution. 
Result so far: 16993.68
Subtracting 7128 from 7240 leaves us with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

On to step 11:
891 can be fit into 1120 1 times, resulting in a remainder of 229.
Record the quotient 1 as the next digit in the result. 
Result so far: 16993.681
If we take 891 away from 1120, we end up with 229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

Step 12:
891 can be fit into 2290 2 times, resulting in a remainder of 508.
Put 2 as the next digit of the answer. 
Result so far: 16993.6812
Subtracting 1782 from 2290 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.

Going ahead to step 13:
5080 divided by 891 is 5 with a remainder of 625.
Use 5 as the next digit of our solution. 
Result so far: 16993.68125
If we subtract 4455 from 5080, we get 625.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6250, and continue the process.

Let's proceed to step 14:
The number 891 fits into 6250 7 times, leaving a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 16993.681257
If we subtract 6237 from 6250, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 15:
891 can be fit into 130 0 times, resulting in a remainder of 130.
Record the quotient 0 as the next digit in the result. 
Result so far: 16993.681257
The remainder is 130 after subtracting 0 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Moving on to step 16:
The number 891 fits into 1300 1 times, leaving a remainder of 409.
Put 1 as the next digit of the answer. 
Result so far: 16993.68125701
The remainder is 409 after subtracting 891 from 1300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4090, and continue the process.

In conclusion, the division gives 16993.68125701 with a balance of 4.09e-07.
