77700999 ÷ 373 
We want to figure out the number of times 77700999 can be divided by 373.

On to step 1:
The number 373 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 373

Going ahead to step 2:
373 can be fit into 77 0 times, resulting in a remainder of 77.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Append the next digit (7) from the dividend to 77 and continue with: 777 / 373

Step 3:
777 divided by 373 is 2 with a remainder of 31.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 746 from 777, we get 31.
Include the next digit (0) from the dividend after 31, then repeat: 310 / 373

Advancing to step 4:
The number 373 fits into 310 0 times, leaving a remainder of 310.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
Deduct 0 from 310 and we're left with 310.
Grab the next digit (0) from the dividend, add it to 310, then carry on: 3100 / 373

Advancing to step 5:
If we divide 3100 by 373, we get 8 and a remainder of 116.
Put 8 as the next digit of the answer. 
Result so far: 208.0
If we take 2984 away from 3100, we end up with 116.
Take the next digit (9) from the dividend and append it to 116, then repeat: 1169 / 373

Let's proceed to step 6:
When dividing 1169 by 373, we get 3 with a remainder of 50.
Use 3 as the next digit of our solution. 
Result so far: 2083.0
The remainder is 50 after subtracting 1119 from 1169.
Append the next digit (9) from the dividend to 50 and continue with: 509 / 373

Moving on to step 7:
373 can be fit into 509 1 times, resulting in a remainder of 136.
The next digit of our result is 1. 
Result so far: 20831.0
The remainder is 136 after subtracting 373 from 509.
Include the next digit (9) from the dividend after 136, then repeat: 1369 / 373

Advancing to step 8:
1369 divided by 373 is 3 with a remainder of 250.
The number 3 becomes the next digit in our result. 
Result so far: 208313.0
Subtract 1119 from 1369 to get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Let's proceed to step 9:
If we divide 2500 by 373, we get 6 and a remainder of 262.
Record the quotient 6 as the next digit in the result. 
Result so far: 208313.6
If we subtract 2238 from 2500, we get 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Advancing to step 10:
373 can be fit into 2620 7 times, resulting in a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 208313.67
If we subtract 2611 from 2620, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 11:
The number 373 fits into 90 0 times, leaving a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 208313.67
The remainder is 90 after subtracting 0 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 12:
373 goes into 900 2 times with a remainder of 154.
The number 2 becomes the next digit in our result. 
Result so far: 208313.6702
The remainder is 154 after subtracting 746 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Step 13:
373 can be fit into 1540 4 times, resulting in a remainder of 48.
Write down 4 as next digit of the result. 
Result so far: 208313.67024
Subtract 1492 from 1540 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 14:
When dividing 480 by 373, we get 1 with a remainder of 107.
Write down 1 as next digit of the result. 
Result so far: 208313.670241
Subtracting 373 from 480 leaves us with 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Step 15:
373 goes into 1070 2 times with a remainder of 324.
The next digit of our result is 2. 
Result so far: 208313.6702412
If we subtract 746 from 1070, we get 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Going ahead to step 16:
The number 373 fits into 3240 8 times, leaving a remainder of 256.
Record the quotient 8 as the next digit in the result. 
Result so far: 208313.67024128
If we subtract 2984 from 3240, we get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

The quotient of the division is 208313.67024128, and the remainder is 2.56e-07.
