77552813 divided by 977 
We want to figure out the number of times 77552813 can be divided by 977.

Step 1:
977 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
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 / 977

Advancing to step 2:
977 goes into 77 0 times with a remainder of 77.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Append the next digit (5) from the dividend to 77 and continue with: 775 / 977

Advancing to step 3:
775 divided by 977 is 0 with a remainder of 775.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 775 to get 775.
Bring next digit (5) of the dividend behind the 775 and repeat the process: 7755 / 977

Advancing to step 4:
977 goes into 7755 7 times with a remainder of 916.
Write down 7 as next digit of the result. 
Result so far: 7.0
Deduct 6839 from 7755 and we're left with 916.
Append the next digit (2) from the dividend to 916 and continue with: 9162 / 977

Advancing to step 5:
The number 977 fits into 9162 9 times, leaving a remainder of 369.
Use 9 as the next digit of our solution. 
Result so far: 79.0
The remainder is 369 after subtracting 8793 from 9162.
Append the next digit (8) from the dividend to 369 and continue with: 3698 / 977

On to step 6:
If we divide 3698 by 977, we get 3 and a remainder of 767.
The next digit of our result is 3. 
Result so far: 793.0
Deduct 2931 from 3698 and we're left with 767.
Grab the next digit (1) from the dividend, add it to 767, then carry on: 7671 / 977

Step 7:
When dividing 7671 by 977, we get 7 with a remainder of 832.
Write down 7 as next digit of the result. 
Result so far: 7937.0
Subtracting 6839 from 7671 leaves us with 832.
Fetch the next digit (3) from the dividend, attach it to 832 and continue: 8323 / 977

Let's proceed to step 8:
8323 divided by 977 is 8 with a remainder of 507.
Record the quotient 8 as the next digit in the result. 
Result so far: 79378.0
Subtract 7816 from 8323 to get 507.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5070, and continue the process.

Let's proceed to step 9:
5070 divided by 977 is 5 with a remainder of 185.
The next digit of our result is 5. 
Result so far: 79378.5
If we take 4885 away from 5070, we end up with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Going ahead to step 10:
The number 977 fits into 1850 1 times, leaving a remainder of 873.
The next digit of our result is 1. 
Result so far: 79378.51
Subtracting 977 from 1850 leaves us with 873.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8730, and continue the process.

Moving on to step 11:
The number 977 fits into 8730 8 times, leaving a remainder of 914.
Write down 8 as next digit of the result. 
Result so far: 79378.518
Deduct 7816 from 8730 and we're left with 914.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9140, and continue the process.

Advancing to step 12:
977 goes into 9140 9 times with a remainder of 347.
Put 9 as the next digit of the answer. 
Result so far: 79378.5189
The remainder is 347 after subtracting 8793 from 9140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3470, and continue the process.

Moving on to step 13:
3470 divided by 977 is 3 with a remainder of 539.
Record the quotient 3 as the next digit in the result. 
Result so far: 79378.51893
Subtracting 2931 from 3470 leaves us with 539.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5390, and continue the process.

Advancing to step 14:
977 goes into 5390 5 times with a remainder of 505.
Use 5 as the next digit of our solution. 
Result so far: 79378.518935
Subtracting 4885 from 5390 leaves us with 505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

Step 15:
977 can be fit into 5050 5 times, resulting in a remainder of 165.
Put 5 as the next digit of the answer. 
Result so far: 79378.5189355
Deduct 4885 from 5050 and we're left with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

The quotient of the division is 79378.5189355, and the remainder is 1.65e-06.
