6171780 ÷ 74 
Our goal is to divide 6171780 by 74.

Advancing to step 1:
If we divide 6 by 74, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 74

Step 2:
74 goes into 61 0 times with a remainder of 61.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 61, we end up with 61.
Include the next digit (7) from the dividend after 61, then repeat: 617 / 74

Advancing to step 3:
617 divided by 74 is 8 with a remainder of 25.
The next digit of our result is 8. 
Result so far: 8.0
If we subtract 592 from 617, we get 25.
Grab the next digit (1) from the dividend, add it to 25, then carry on: 251 / 74

Moving on to step 4:
251 divided by 74 is 3 with a remainder of 29.
Put 3 as the next digit of the answer. 
Result so far: 83.0
If we subtract 222 from 251, we get 29.
Bring next digit (7) of the dividend behind the 29 and repeat the process: 297 / 74

Advancing to step 5:
If we divide 297 by 74, we get 4 and a remainder of 1.
The next digit of our result is 4. 
Result so far: 834.0
Deduct 296 from 297 and we're left with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 74

On to step 6:
When dividing 18 by 74, we get 0 with a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 8340.0
If we take 0 away from 18, we end up with 18.
Include the next digit (0) from the dividend after 18, then repeat: 180 / 74

Step 7:
74 can be fit into 180 2 times, resulting in a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 83402.0
Subtracting 148 from 180 leaves us 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.

Step 8:
When dividing 320 by 74, we get 4 with a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 83402.4
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.

Let's proceed to step 9:
The number 74 fits into 240 3 times, leaving a remainder of 18.
Use 3 as the next digit of our solution. 
Result so far: 83402.43
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 10:
When dividing 180 by 74, we get 2 with a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 83402.432
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.

On to step 11:
74 goes into 320 4 times with a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 83402.4324
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 12:
When dividing 240 by 74, we get 3 with a remainder of 18.
The next digit of our result is 3. 
Result so far: 83402.43243
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.

Let's proceed to step 13:
If we divide 180 by 74, we get 2 and a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 83402.432432
Subtracting 148 from 180 leaves us 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.

Step 14:
The number 74 fits into 320 4 times, leaving a remainder of 24.
The next digit of our result is 4. 
Result so far: 83402.4324324
Subtract 296 from 320 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 15:
If we divide 240 by 74, we get 3 and a remainder of 18.
Write down 3 as next digit of the result. 
Result so far: 83402.43243243
If we take 222 away from 240, we end up 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.

The final result is 83402.43243243 with a remainder of 1.8e-08.
