98970129 ÷ 77 
Our goal is to divide 98970129 by 77.

Step 1:
When dividing 9 by 77, we get 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Bring next digit (8) of the dividend behind the 9 and repeat the process: 98 / 77

Moving on to step 2:
77 can be fit into 98 1 times, resulting in a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 77 from 98, we get 21.
Bring next digit (9) of the dividend behind the 21 and repeat the process: 219 / 77

Let's proceed to step 3:
77 goes into 219 2 times with a remainder of 65.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we take 154 away from 219, we end up with 65.
Take the next digit (7) from the dividend and append it to 65, then repeat: 657 / 77

Going ahead to step 4:
657 divided by 77 is 8 with a remainder of 41.
Record the quotient 8 as the next digit in the result. 
Result so far: 128.0
The remainder is 41 after subtracting 616 from 657.
Fetch the next digit (0) from the dividend, attach it to 41 and continue: 410 / 77

Let's proceed to step 5:
410 divided by 77 is 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 1285.0
If we subtract 385 from 410, we get 25.
Fetch the next digit (1) from the dividend, attach it to 25 and continue: 251 / 77

Let's proceed to step 6:
77 can be fit into 251 3 times, resulting in a remainder of 20.
Record the quotient 3 as the next digit in the result. 
Result so far: 12853.0
If we subtract 231 from 251, we get 20.
Append the next digit (2) from the dividend to 20 and continue with: 202 / 77

Advancing to step 7:
If we divide 202 by 77, we get 2 and a remainder of 48.
Record the quotient 2 as the next digit in the result. 
Result so far: 128532.0
If we subtract 154 from 202, we get 48.
Include the next digit (9) from the dividend after 48, then repeat: 489 / 77

Advancing to step 8:
The number 77 fits into 489 6 times, leaving a remainder of 27.
The next digit of our result is 6. 
Result so far: 1285326.0
Subtracting 462 from 489 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 9:
When dividing 270 by 77, we get 3 with a remainder of 39.
Record the quotient 3 as the next digit in the result. 
Result so far: 1285326.3
Subtract 231 from 270 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 10:
77 can be fit into 390 5 times, resulting in a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 1285326.35
If we take 385 away from 390, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 11:
50 divided by 77 is 0 with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 1285326.35
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 12:
77 goes into 500 6 times with a remainder of 38.
Record the quotient 6 as the next digit in the result. 
Result so far: 1285326.3506
Deduct 462 from 500 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 13:
77 goes into 380 4 times with a remainder of 72.
Write down 4 as next digit of the result. 
Result so far: 1285326.35064
The remainder is 72 after subtracting 308 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 14:
720 divided by 77 is 9 with a remainder of 27.
The next digit of our result is 9. 
Result so far: 1285326.350649
The remainder is 27 after subtracting 693 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 15:
77 can be fit into 270 3 times, resulting in a remainder of 39.
The number 3 becomes the next digit in our result. 
Result so far: 1285326.3506493
Subtracting 231 from 270 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 16:
When dividing 390 by 77, we get 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 1285326.35064935
Subtract 385 from 390 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Our division results in 1285326.35064935 with a remaining 5e-09.
