We divide 81987245 by 811
We want to figure out the number of times 81987245 can be divided by 811.

Let's proceed to step 1:
If we divide 8 by 811, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 811

On to step 2:
811 can be fit into 81 0 times, resulting in a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Append the next digit (9) from the dividend to 81 and continue with: 819 / 811

Step 3:
When dividing 819 by 811, we get 1 with a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 811 from 819 leaves us with 8.
Grab the next digit (8) from the dividend, add it to 8, then carry on: 88 / 811

Let's proceed to step 4:
811 can be fit into 88 0 times, resulting in a remainder of 88.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
The remainder is 88 after subtracting 0 from 88.
Grab the next digit (7) from the dividend, add it to 88, then carry on: 887 / 811

Step 5:
If we divide 887 by 811, we get 1 and a remainder of 76.
Write down 1 as next digit of the result. 
Result so far: 101.0
Subtract 811 from 887 to get 76.
Fetch the next digit (2) from the dividend, attach it to 76 and continue: 762 / 811

On to step 6:
811 goes into 762 0 times with a remainder of 762.
The next digit of our result is 0. 
Result so far: 1010.0
If we take 0 away from 762, we end up with 762.
Take the next digit (4) from the dividend and append it to 762, then repeat: 7624 / 811

Let's proceed to step 7:
When dividing 7624 by 811, we get 9 with a remainder of 325.
Put 9 as the next digit of the answer. 
Result so far: 10109.0
Deduct 7299 from 7624 and we're left with 325.
Fetch the next digit (5) from the dividend, attach it to 325 and continue: 3255 / 811

Advancing to step 8:
The number 811 fits into 3255 4 times, leaving a remainder of 11.
Put 4 as the next digit of the answer. 
Result so far: 101094.0
The remainder is 11 after subtracting 3244 from 3255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 9:
The number 811 fits into 110 0 times, leaving a remainder of 110.
Record the quotient 0 as the next digit in the result. 
Result so far: 101094.0
Subtracting 0 from 110 leaves us with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

On to step 10:
1100 divided by 811 is 1 with a remainder of 289.
The next digit of our result is 1. 
Result so far: 101094.01
If we take 811 away from 1100, we end up with 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

Let's proceed to step 11:
811 goes into 2890 3 times with a remainder of 457.
The number 3 becomes the next digit in our result. 
Result so far: 101094.013
Deduct 2433 from 2890 and we're left with 457.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4570, and continue the process.

Let's proceed to step 12:
If we divide 4570 by 811, we get 5 and a remainder of 515.
The number 5 becomes the next digit in our result. 
Result so far: 101094.0135
If we subtract 4055 from 4570, we get 515.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5150, and continue the process.

Going ahead to step 13:
811 can be fit into 5150 6 times, resulting in a remainder of 284.
Record the quotient 6 as the next digit in the result. 
Result so far: 101094.01356
The remainder is 284 after subtracting 4866 from 5150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Step 14:
811 goes into 2840 3 times with a remainder of 407.
Write down 3 as next digit of the result. 
Result so far: 101094.013563
If we subtract 2433 from 2840, we get 407.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4070, and continue the process.

On to step 15:
4070 divided by 811 is 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 101094.0135635
If we subtract 4055 from 4070, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 16:
150 divided by 811 is 0 with a remainder of 150.
The number 0 becomes the next digit in our result. 
Result so far: 101094.0135635
Subtracting 0 from 150 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Our division results in 101094.0135635 with a remaining 1.5e-07.
