Let's divide 78345661 by 267
We want to figure out the number of times 78345661 can be divided by 267.

Going ahead to step 1:
When dividing 7 by 267, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 267

Moving on to step 2:
267 goes into 78 0 times with a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Fetch the next digit (3) from the dividend, attach it to 78 and continue: 783 / 267

Going ahead to step 3:
267 can be fit into 783 2 times, resulting in a remainder of 249.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 534 from 783, we get 249.
Grab the next digit (4) from the dividend, add it to 249, then carry on: 2494 / 267

Advancing to step 4:
2494 divided by 267 is 9 with a remainder of 91.
Use 9 as the next digit of our solution. 
Result so far: 29.0
If we subtract 2403 from 2494, we get 91.
Grab the next digit (5) from the dividend, add it to 91, then carry on: 915 / 267

Step 5:
The number 267 fits into 915 3 times, leaving a remainder of 114.
The next digit of our result is 3. 
Result so far: 293.0
Deduct 801 from 915 and we're left with 114.
Append the next digit (6) from the dividend to 114 and continue with: 1146 / 267

Moving on to step 6:
If we divide 1146 by 267, we get 4 and a remainder of 78.
The number 4 becomes the next digit in our result. 
Result so far: 2934.0
Deduct 1068 from 1146 and we're left with 78.
Include the next digit (6) from the dividend after 78, then repeat: 786 / 267

Step 7:
If we divide 786 by 267, we get 2 and a remainder of 252.
Put 2 as the next digit of the answer. 
Result so far: 29342.0
Subtracting 534 from 786 leaves us with 252.
Include the next digit (1) from the dividend after 252, then repeat: 2521 / 267

Let's proceed to step 8:
The number 267 fits into 2521 9 times, leaving a remainder of 118.
Use 9 as the next digit of our solution. 
Result so far: 293429.0
Deduct 2403 from 2521 and we're left with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Step 9:
The number 267 fits into 1180 4 times, leaving a remainder of 112.
The next digit of our result is 4. 
Result so far: 293429.4
Deduct 1068 from 1180 and we're left with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Step 10:
267 goes into 1120 4 times with a remainder of 52.
The number 4 becomes the next digit in our result. 
Result so far: 293429.44
Deduct 1068 from 1120 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Our division results in 293429.44 with a remaining 0.052.
