812100 ÷ 74 
We want to figure out the number of times 812100 can be divided by 74.

Advancing to step 1:
If we divide 8 by 74, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 74

Going ahead to step 2:
If we divide 81 by 74, we get 1 and a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 74 from 81 leaves us with 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 74

Going ahead to step 3:
74 goes into 72 0 times with a remainder of 72.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtract 0 from 72 to get 72.
Bring next digit (1) of the dividend behind the 72 and repeat the process: 721 / 74

Moving on to step 4:
721 divided by 74 is 9 with a remainder of 55.
Put 9 as the next digit of the answer. 
Result so far: 109.0
If we take 666 away from 721, we end up with 55.
Take the next digit (0) from the dividend and append it to 55, then repeat: 550 / 74

Step 5:
74 goes into 550 7 times with a remainder of 32.
The next digit of our result is 7. 
Result so far: 1097.0
Subtracting 518 from 550 leaves us with 32.
Take the next digit (0) from the dividend and append it to 32, then repeat: 320 / 74

On to step 6:
74 can be fit into 320 4 times, resulting in a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 10974.0
The remainder is 24 after subtracting 296 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 7:
The number 74 fits into 240 3 times, leaving a remainder of 18.
Put 3 as the next digit of the answer. 
Result so far: 10974.3
Deduct 222 from 240 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 8:
When dividing 180 by 74, we get 2 with a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 10974.32
Deduct 148 from 180 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 9:
The number 74 fits into 320 4 times, leaving a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 10974.324
If we take 296 away from 320, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 10:
74 goes into 240 3 times with a remainder of 18.
Use 3 as the next digit of our solution. 
Result so far: 10974.3243
Deduct 222 from 240 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 11:
74 can be fit into 180 2 times, resulting in a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 10974.32432
The remainder is 32 after subtracting 148 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 12:
When dividing 320 by 74, we get 4 with a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 10974.324324
Subtracting 296 from 320 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 13:
The number 74 fits into 240 3 times, leaving a remainder of 18.
Put 3 as the next digit of the answer. 
Result so far: 10974.3243243
The remainder is 18 after subtracting 222 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 14:
When dividing 180 by 74, we get 2 with a remainder of 32.
The next digit of our result is 2. 
Result so far: 10974.32432432
The remainder is 32 after subtracting 148 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final result is 10974.32432432 with a remainder of 3.2e-08.
