We divide 100970 by 81
We're looking to find how many times 81 goes into 100970.

Moving on to step 1:
If we divide 1 by 81, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 81

Moving on to step 2:
81 can be fit into 10 0 times, resulting in a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 10 to get 10.
Append the next digit (0) from the dividend to 10 and continue with: 100 / 81

Step 3:
The number 81 fits into 100 1 times, leaving a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 81 from 100 and we're left with 19.
Grab the next digit (9) from the dividend, add it to 19, then carry on: 199 / 81

Going ahead to step 4:
The number 81 fits into 199 2 times, leaving a remainder of 37.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we subtract 162 from 199, we get 37.
Grab the next digit (7) from the dividend, add it to 37, then carry on: 377 / 81

Step 5:
If we divide 377 by 81, we get 4 and a remainder of 53.
Record the quotient 4 as the next digit in the result. 
Result so far: 124.0
Deduct 324 from 377 and we're left with 53.
Bring next digit (0) of the dividend behind the 53 and repeat the process: 530 / 81

Step 6:
When dividing 530 by 81, we get 6 with a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 1246.0
Deduct 486 from 530 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 7:
81 can be fit into 440 5 times, resulting in a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 1246.5
Subtracting 405 from 440 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 8:
When dividing 350 by 81, we get 4 with a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 1246.54
If we take 324 away from 350, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 9:
81 goes into 260 3 times with a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 1246.543
Deduct 243 from 260 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 10:
81 can be fit into 170 2 times, resulting in a remainder of 8.
The next digit of our result is 2. 
Result so far: 1246.5432
If we subtract 162 from 170, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 11:
81 can be fit into 80 0 times, resulting in a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 1246.5432
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 12:
When dividing 800 by 81, we get 9 with a remainder of 71.
Use 9 as the next digit of our solution. 
Result so far: 1246.543209
The remainder is 71 after subtracting 729 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Moving on to step 13:
81 can be fit into 710 8 times, resulting in a remainder of 62.
Use 8 as the next digit of our solution. 
Result so far: 1246.5432098
Deduct 648 from 710 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 14:
620 divided by 81 is 7 with a remainder of 53.
Write down 7 as next digit of the result. 
Result so far: 1246.54320987
Subtracting 567 from 620 leaves us with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

The quotient of the division is 1246.54320987, and the remainder is 5.3e-08.
