81641394 ÷ 79 
We're looking to find how many times 79 goes into 81641394.

Let's proceed to step 1:
8 divided by 79 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 79

On to step 2:
When dividing 81 by 79, we get 1 with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 79 from 81 leaves us with 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 79

Moving on to step 3:
If we divide 26 by 79, we get 0 and a remainder of 26.
The next digit of our result is 0. 
Result so far: 10.0
If we subtract 0 from 26, we get 26.
Fetch the next digit (4) from the dividend, attach it to 26 and continue: 264 / 79

Advancing to step 4:
79 can be fit into 264 3 times, resulting in a remainder of 27.
The next digit of our result is 3. 
Result so far: 103.0
Subtracting 237 from 264 leaves us with 27.
Fetch the next digit (1) from the dividend, attach it to 27 and continue: 271 / 79

On to step 5:
79 can be fit into 271 3 times, resulting in a remainder of 34.
Use 3 as the next digit of our solution. 
Result so far: 1033.0
If we subtract 237 from 271, we get 34.
Take the next digit (3) from the dividend and append it to 34, then repeat: 343 / 79

Moving on to step 6:
79 can be fit into 343 4 times, resulting in a remainder of 27.
Use 4 as the next digit of our solution. 
Result so far: 10334.0
Subtract 316 from 343 to get 27.
Take the next digit (9) from the dividend and append it to 27, then repeat: 279 / 79

Advancing to step 7:
When dividing 279 by 79, we get 3 with a remainder of 42.
Record the quotient 3 as the next digit in the result. 
Result so far: 103343.0
Deduct 237 from 279 and we're left with 42.
Bring next digit (4) of the dividend behind the 42 and repeat the process: 424 / 79

Moving on to step 8:
If we divide 424 by 79, we get 5 and a remainder of 29.
Use 5 as the next digit of our solution. 
Result so far: 1033435.0
Subtract 395 from 424 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 9:
290 divided by 79 is 3 with a remainder of 53.
Put 3 as the next digit of the answer. 
Result so far: 1033435.3
If we take 237 away from 290, we end up 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.

Step 10:
530 divided by 79 is 6 with a remainder of 56.
Record the quotient 6 as the next digit in the result. 
Result so far: 1033435.36
The remainder is 56 after subtracting 474 from 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 11:
79 can be fit into 560 7 times, resulting in a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 1033435.367
The remainder is 7 after subtracting 553 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 12:
The number 79 fits into 70 0 times, leaving a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 1033435.367
If we take 0 away from 70, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 13:
When dividing 700 by 79, we get 8 with a remainder of 68.
Write down 8 as next digit of the result. 
Result so far: 1033435.36708
Subtract 632 from 700 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 14:
79 goes into 680 8 times with a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 1033435.367088
If we take 632 away from 680, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

After the division, we end up with 1033435.367088 and a remainder of 4.8e-06.
