Let's divide 81987214 by 738
The aim is to understand the frequency of 738 in 81987214.

Let's proceed to step 1:
When dividing 8 by 738, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 738

Step 2:
When dividing 81 by 738, we get 0 with a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Grab the next digit (9) from the dividend, add it to 81, then carry on: 819 / 738

Step 3:
The number 738 fits into 819 1 times, leaving a remainder of 81.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 81 after subtracting 738 from 819.
Append the next digit (8) from the dividend to 81 and continue with: 818 / 738

Moving on to step 4:
When dividing 818 by 738, we get 1 with a remainder of 80.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we subtract 738 from 818, we get 80.
Append the next digit (7) from the dividend to 80 and continue with: 807 / 738

Advancing to step 5:
807 divided by 738 is 1 with a remainder of 69.
The number 1 becomes the next digit in our result. 
Result so far: 111.0
Subtract 738 from 807 to get 69.
Append the next digit (2) from the dividend to 69 and continue with: 692 / 738

On to step 6:
When dividing 692 by 738, we get 0 with a remainder of 692.
The next digit of our result is 0. 
Result so far: 1110.0
Subtract 0 from 692 to get 692.
Include the next digit (1) from the dividend after 692, then repeat: 6921 / 738

Going ahead to step 7:
738 goes into 6921 9 times with a remainder of 279.
Record the quotient 9 as the next digit in the result. 
Result so far: 11109.0
If we take 6642 away from 6921, we end up with 279.
Grab the next digit (4) from the dividend, add it to 279, then carry on: 2794 / 738

Let's proceed to step 8:
When dividing 2794 by 738, we get 3 with a remainder of 580.
Use 3 as the next digit of our solution. 
Result so far: 111093.0
The remainder is 580 after subtracting 2214 from 2794.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Going ahead to step 9:
The number 738 fits into 5800 7 times, leaving a remainder of 634.
Put 7 as the next digit of the answer. 
Result so far: 111093.7
Subtracting 5166 from 5800 leaves us with 634.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6340, and continue the process.

Advancing to step 10:
When dividing 6340 by 738, we get 8 with a remainder of 436.
The next digit of our result is 8. 
Result so far: 111093.78
Subtracting 5904 from 6340 leaves us with 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

Going ahead to step 11:
738 goes into 4360 5 times with a remainder of 670.
Write down 5 as next digit of the result. 
Result so far: 111093.785
If we take 3690 away from 4360, we end up with 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

Step 12:
738 can be fit into 6700 9 times, resulting in a remainder of 58.
The number 9 becomes the next digit in our result. 
Result so far: 111093.7859
Deduct 6642 from 6700 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 13:
738 goes into 580 0 times with a remainder of 580.
Put 0 as the next digit of the answer. 
Result so far: 111093.7859
Subtract 0 from 580 to get 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

On to step 14:
The number 738 fits into 5800 7 times, leaving a remainder of 634.
Write down 7 as next digit of the result. 
Result so far: 111093.785907
Subtracting 5166 from 5800 leaves us with 634.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6340, and continue the process.

Going ahead to step 15:
738 can be fit into 6340 8 times, resulting in a remainder of 436.
The number 8 becomes the next digit in our result. 
Result so far: 111093.7859078
Subtracting 5904 from 6340 leaves us with 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

Step 16:
4360 divided by 738 is 5 with a remainder of 670.
Write down 5 as next digit of the result. 
Result so far: 111093.78590785
Subtract 3690 from 4360 to get 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

After the division, we end up with 111093.78590785 and a remainder of 6.7e-07.
