77664140 ÷ 46 
We want to figure out the number of times 77664140 can be divided by 46.

Going ahead to step 1:
7 divided by 46 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 46

On to step 2:
77 divided by 46 is 1 with a remainder of 31.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 46 from 77 to get 31.
Fetch the next digit (6) from the dividend, attach it to 31 and continue: 316 / 46

Moving on to step 3:
The number 46 fits into 316 6 times, leaving a remainder of 40.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
If we take 276 away from 316, we end up with 40.
Grab the next digit (6) from the dividend, add it to 40, then carry on: 406 / 46

Moving on to step 4:
406 divided by 46 is 8 with a remainder of 38.
Use 8 as the next digit of our solution. 
Result so far: 168.0
Deduct 368 from 406 and we're left with 38.
Fetch the next digit (4) from the dividend, attach it to 38 and continue: 384 / 46

Step 5:
If we divide 384 by 46, we get 8 and a remainder of 16.
The next digit of our result is 8. 
Result so far: 1688.0
Subtract 368 from 384 to get 16.
Fetch the next digit (1) from the dividend, attach it to 16 and continue: 161 / 46

Advancing to step 6:
When dividing 161 by 46, we get 3 with a remainder of 23.
Put 3 as the next digit of the answer. 
Result so far: 16883.0
The remainder is 23 after subtracting 138 from 161.
Append the next digit (4) from the dividend to 23 and continue with: 234 / 46

Going ahead to step 7:
When dividing 234 by 46, we get 5 with a remainder of 4.
The number 5 becomes the next digit in our result. 
Result so far: 168835.0
Subtracting 230 from 234 leaves us with 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 46

Moving on to step 8:
When dividing 40 by 46, we get 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 1688350.0
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 9:
The number 46 fits into 400 8 times, leaving a remainder of 32.
The next digit of our result is 8. 
Result so far: 1688350.8
The remainder is 32 after subtracting 368 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 10:
46 can be fit into 320 6 times, resulting in a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 1688350.86
Subtracting 276 from 320 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 11:
46 can be fit into 440 9 times, resulting in a remainder of 26.
The number 9 becomes the next digit in our result. 
Result so far: 1688350.869
Subtracting 414 from 440 leaves us 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.

Step 12:
When dividing 260 by 46, we get 5 with a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 1688350.8695
If we take 230 away from 260, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 13:
When dividing 300 by 46, we get 6 with a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 1688350.86956
Deduct 276 from 300 and we're left 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.

On to step 14:
46 can be fit into 240 5 times, resulting in a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 1688350.869565
Deduct 230 from 240 and we're left 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 15:
100 divided by 46 is 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 1688350.8695652
If we subtract 92 from 100, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 16:
If we divide 80 by 46, we get 1 and a remainder of 34.
Record the quotient 1 as the next digit in the result. 
Result so far: 1688350.86956521
If we subtract 46 from 80, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

The final outcome is 1688350.86956521, with a leftover of 3.4e-08.
