Let's divide 77880483 by 669
Our goal is to divide 77880483 by 669.

Advancing to step 1:
The number 669 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 669

Going ahead to step 2:
When dividing 77 by 669, we get 0 with a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Grab the next digit (8) from the dividend, add it to 77, then carry on: 778 / 669

On to step 3:
If we divide 778 by 669, we get 1 and a remainder of 109.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 109 after subtracting 669 from 778.
Include the next digit (8) from the dividend after 109, then repeat: 1098 / 669

Step 4:
When dividing 1098 by 669, we get 1 with a remainder of 429.
The next digit of our result is 1. 
Result so far: 11.0
If we subtract 669 from 1098, we get 429.
Fetch the next digit (0) from the dividend, attach it to 429 and continue: 4290 / 669

Going ahead to step 5:
When dividing 4290 by 669, we get 6 with a remainder of 276.
The number 6 becomes the next digit in our result. 
Result so far: 116.0
Deduct 4014 from 4290 and we're left with 276.
Append the next digit (4) from the dividend to 276 and continue with: 2764 / 669

On to step 6:
If we divide 2764 by 669, we get 4 and a remainder of 88.
Use 4 as the next digit of our solution. 
Result so far: 1164.0
If we subtract 2676 from 2764, we get 88.
Append the next digit (8) from the dividend to 88 and continue with: 888 / 669

Step 7:
When dividing 888 by 669, we get 1 with a remainder of 219.
Record the quotient 1 as the next digit in the result. 
Result so far: 11641.0
If we take 669 away from 888, we end up with 219.
Take the next digit (3) from the dividend and append it to 219, then repeat: 2193 / 669

Going ahead to step 8:
If we divide 2193 by 669, we get 3 and a remainder of 186.
Write down 3 as next digit of the result. 
Result so far: 116413.0
If we subtract 2007 from 2193, we get 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Going ahead to step 9:
669 goes into 1860 2 times with a remainder of 522.
The next digit of our result is 2. 
Result so far: 116413.2
If we take 1338 away from 1860, we end up with 522.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5220, and continue the process.

Advancing to step 10:
The number 669 fits into 5220 7 times, leaving a remainder of 537.
Put 7 as the next digit of the answer. 
Result so far: 116413.27
Deduct 4683 from 5220 and we're left with 537.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5370, and continue the process.

Advancing to step 11:
The number 669 fits into 5370 8 times, leaving a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 116413.278
Subtracting 5352 from 5370 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 12:
The number 669 fits into 180 0 times, leaving a remainder of 180.
The next digit of our result is 0. 
Result so far: 116413.278
If we subtract 0 from 180, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 13:
669 can be fit into 1800 2 times, resulting in a remainder of 462.
The next digit of our result is 2. 
Result so far: 116413.27802
Deduct 1338 from 1800 and we're left with 462.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

Advancing to step 14:
669 goes into 4620 6 times with a remainder of 606.
The next digit of our result is 6. 
Result so far: 116413.278026
If we subtract 4014 from 4620, we get 606.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6060, and continue the process.

Step 15:
When dividing 6060 by 669, we get 9 with a remainder of 39.
The next digit of our result is 9. 
Result so far: 116413.2780269
The remainder is 39 after subtracting 6021 from 6060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 16:
If we divide 390 by 669, we get 0 and a remainder of 390.
The next digit of our result is 0. 
Result so far: 116413.2780269
If we take 0 away from 390, we end up with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

The final outcome is 116413.2780269, with a leftover of 3.9e-07.
