78746684 ÷ 77 
We're looking to find how many times 77 goes into 78746684.

On to step 1:
When dividing 7 by 77, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 77

Going ahead to step 2:
77 can be fit into 78 1 times, resulting in a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 77 away from 78, we end up with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 77

On to step 3:
If we divide 17 by 77, we get 0 and a remainder of 17.
The next digit of our result is 0. 
Result so far: 10.0
Deduct 0 from 17 and we're left with 17.
Fetch the next digit (4) from the dividend, attach it to 17 and continue: 174 / 77

Let's proceed to step 4:
The number 77 fits into 174 2 times, leaving a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 102.0
Subtracting 154 from 174 leaves us with 20.
Include the next digit (6) from the dividend after 20, then repeat: 206 / 77

On to step 5:
206 divided by 77 is 2 with a remainder of 52.
Use 2 as the next digit of our solution. 
Result so far: 1022.0
Subtract 154 from 206 to get 52.
Bring next digit (6) of the dividend behind the 52 and repeat the process: 526 / 77

Advancing to step 6:
The number 77 fits into 526 6 times, leaving a remainder of 64.
The next digit of our result is 6. 
Result so far: 10226.0
Deduct 462 from 526 and we're left with 64.
Include the next digit (8) from the dividend after 64, then repeat: 648 / 77

Let's proceed to step 7:
If we divide 648 by 77, we get 8 and a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 102268.0
Subtracting 616 from 648 leaves us with 32.
Take the next digit (4) from the dividend and append it to 32, then repeat: 324 / 77

Moving on to step 8:
77 can be fit into 324 4 times, resulting in a remainder of 16.
The next digit of our result is 4. 
Result so far: 1022684.0
The remainder is 16 after subtracting 308 from 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 9:
If we divide 160 by 77, we get 2 and a remainder of 6.
The next digit of our result is 2. 
Result so far: 1022684.2
Subtracting 154 from 160 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 10:
60 divided by 77 is 0 with a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 1022684.2
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 11:
600 divided by 77 is 7 with a remainder of 61.
The number 7 becomes the next digit in our result. 
Result so far: 1022684.207
Subtract 539 from 600 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Advancing to step 12:
610 divided by 77 is 7 with a remainder of 71.
Put 7 as the next digit of the answer. 
Result so far: 1022684.2077
If we take 539 away from 610, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Our division results in 1022684.2077 with a remaining 0.00071.
