85623436 divided by 981 
The aim is to understand the frequency of 981 in 85623436.

Going ahead to step 1:
If we divide 8 by 981, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 981

Advancing to step 2:
85 divided by 981 is 0 with a remainder of 85.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 85, we get 85.
Grab the next digit (6) from the dividend, add it to 85, then carry on: 856 / 981

Moving on to step 3:
If we divide 856 by 981, we get 0 and a remainder of 856.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 856, we end up with 856.
Fetch the next digit (2) from the dividend, attach it to 856 and continue: 8562 / 981

Going ahead to step 4:
When dividing 8562 by 981, we get 8 with a remainder of 714.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we subtract 7848 from 8562, we get 714.
Fetch the next digit (3) from the dividend, attach it to 714 and continue: 7143 / 981

Step 5:
981 goes into 7143 7 times with a remainder of 276.
Put 7 as the next digit of the answer. 
Result so far: 87.0
Subtract 6867 from 7143 to get 276.
Grab the next digit (4) from the dividend, add it to 276, then carry on: 2764 / 981

On to step 6:
981 goes into 2764 2 times with a remainder of 802.
Put 2 as the next digit of the answer. 
Result so far: 872.0
If we take 1962 away from 2764, we end up with 802.
Include the next digit (3) from the dividend after 802, then repeat: 8023 / 981

Let's proceed to step 7:
8023 divided by 981 is 8 with a remainder of 175.
The next digit of our result is 8. 
Result so far: 8728.0
Deduct 7848 from 8023 and we're left with 175.
Include the next digit (6) from the dividend after 175, then repeat: 1756 / 981

Moving on to step 8:
If we divide 1756 by 981, we get 1 and a remainder of 775.
The next digit of our result is 1. 
Result so far: 87281.0
Deduct 981 from 1756 and we're left with 775.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7750, and continue the process.

Advancing to step 9:
The number 981 fits into 7750 7 times, leaving a remainder of 883.
Put 7 as the next digit of the answer. 
Result so far: 87281.7
Deduct 6867 from 7750 and we're left with 883.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8830, and continue the process.

Moving on to step 10:
When dividing 8830 by 981, we get 9 with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 87281.79
If we take 8829 away from 8830, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 11:
981 goes into 10 0 times with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 87281.79
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 12:
981 goes into 100 0 times with a remainder of 100.
The next digit of our result is 0. 
Result so far: 87281.79
Deduct 0 from 100 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final result is 87281.79 with a remainder of 0.001.
