77385021 divided by 220 
Our goal is to divide 77385021 by 220.

Moving on to step 1:
220 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 220

Let's proceed to step 2:
77 divided by 220 is 0 with a remainder of 77.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Bring next digit (3) of the dividend behind the 77 and repeat the process: 773 / 220

Advancing to step 3:
773 divided by 220 is 3 with a remainder of 113.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 660 from 773 and we're left with 113.
Fetch the next digit (8) from the dividend, attach it to 113 and continue: 1138 / 220

Step 4:
When dividing 1138 by 220, we get 5 with a remainder of 38.
Put 5 as the next digit of the answer. 
Result so far: 35.0
The remainder is 38 after subtracting 1100 from 1138.
Take the next digit (5) from the dividend and append it to 38, then repeat: 385 / 220

Going ahead to step 5:
385 divided by 220 is 1 with a remainder of 165.
Put 1 as the next digit of the answer. 
Result so far: 351.0
Subtract 220 from 385 to get 165.
Fetch the next digit (0) from the dividend, attach it to 165 and continue: 1650 / 220

Moving on to step 6:
If we divide 1650 by 220, we get 7 and a remainder of 110.
Write down 7 as next digit of the result. 
Result so far: 3517.0
Subtract 1540 from 1650 to get 110.
Include the next digit (2) from the dividend after 110, then repeat: 1102 / 220

Let's proceed to step 7:
220 goes into 1102 5 times with a remainder of 2.
Record the quotient 5 as the next digit in the result. 
Result so far: 35175.0
If we take 1100 away from 1102, we end up with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 220

On to step 8:
When dividing 21 by 220, we get 0 with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 351750.0
Subtracting 0 from 21 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 9:
If we divide 210 by 220, we get 0 and a remainder of 210.
The number 0 becomes the next digit in our result. 
Result so far: 351750.0
If we take 0 away from 210, we end up with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Step 10:
If we divide 2100 by 220, we get 9 and a remainder of 120.
Write down 9 as next digit of the result. 
Result so far: 351750.09
Subtract 1980 from 2100 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 11:
When dividing 1200 by 220, we get 5 with a remainder of 100.
Record the quotient 5 as the next digit in the result. 
Result so far: 351750.095
Deduct 1100 from 1200 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 12:
1000 divided by 220 is 4 with a remainder of 120.
The number 4 becomes the next digit in our result. 
Result so far: 351750.0954
The remainder is 120 after subtracting 880 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 13:
220 can be fit into 1200 5 times, resulting in a remainder of 100.
The next digit of our result is 5. 
Result so far: 351750.09545
If we take 1100 away from 1200, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 14:
220 can be fit into 1000 4 times, resulting in a remainder of 120.
Use 4 as the next digit of our solution. 
Result so far: 351750.095454
If we subtract 880 from 1000, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 15:
If we divide 1200 by 220, we get 5 and a remainder of 100.
Record the quotient 5 as the next digit in the result. 
Result so far: 351750.0954545
The remainder is 100 after subtracting 1100 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 16:
220 goes into 1000 4 times with a remainder of 120.
Write down 4 as next digit of the result. 
Result so far: 351750.09545454
If we subtract 880 from 1000, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

The quotient of the division is 351750.09545454, and the remainder is 1.2e-07.
