81643202 ÷ 74 
Let's see how many times 74 fits into 81643202.

Step 1:
The number 74 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 74

Advancing to step 2:
74 can be fit into 81 1 times, resulting in a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 74 away from 81, we end up with 7.
Take the next digit (6) from the dividend and append it to 7, then repeat: 76 / 74

Advancing to step 3:
The number 74 fits into 76 1 times, leaving a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 11.0
The remainder is 2 after subtracting 74 from 76.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 74

On to step 4:
If we divide 24 by 74, we get 0 and a remainder of 24.
Record the quotient 0 as the next digit in the result. 
Result so far: 110.0
Subtract 0 from 24 to get 24.
Grab the next digit (3) from the dividend, add it to 24, then carry on: 243 / 74

Moving on to step 5:
243 divided by 74 is 3 with a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 1103.0
If we subtract 222 from 243, we get 21.
Fetch the next digit (2) from the dividend, attach it to 21 and continue: 212 / 74

On to step 6:
The number 74 fits into 212 2 times, leaving a remainder of 64.
The next digit of our result is 2. 
Result so far: 11032.0
If we subtract 148 from 212, we get 64.
Fetch the next digit (0) from the dividend, attach it to 64 and continue: 640 / 74

Advancing to step 7:
74 can be fit into 640 8 times, resulting in a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 110328.0
The remainder is 48 after subtracting 592 from 640.
Fetch the next digit (2) from the dividend, attach it to 48 and continue: 482 / 74

Advancing to step 8:
74 can be fit into 482 6 times, resulting in a remainder of 38.
Write down 6 as next digit of the result. 
Result so far: 1103286.0
Subtract 444 from 482 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 9:
380 divided by 74 is 5 with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 1103286.5
Subtract 370 from 380 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 10:
The number 74 fits into 100 1 times, leaving a remainder of 26.
The number 1 becomes the next digit in our result. 
Result so far: 1103286.51
Deduct 74 from 100 and we're left 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.

Moving on to step 11:
If we divide 260 by 74, we get 3 and a remainder of 38.
Put 3 as the next digit of the answer. 
Result so far: 1103286.513
If we subtract 222 from 260, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 12:
74 goes into 380 5 times with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 1103286.5135
If we take 370 away from 380, we end up 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 13:
If we divide 100 by 74, we get 1 and a remainder of 26.
The next digit of our result is 1. 
Result so far: 1103286.51351
Subtract 74 from 100 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 14:
74 can be fit into 260 3 times, resulting in a remainder of 38.
The number 3 becomes the next digit in our result. 
Result so far: 1103286.513513
Subtract 222 from 260 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 15:
If we divide 380 by 74, we get 5 and a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 1103286.5135135
Subtracting 370 from 380 leaves us 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 16:
100 divided by 74 is 1 with a remainder of 26.
Use 1 as the next digit of our solution. 
Result so far: 1103286.51351351
The remainder is 26 after subtracting 74 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

After the division, we end up with 1103286.51351351 and a remainder of 2.6e-08.
