63880006 ÷ 986 
We're looking to find how many times 986 goes into 63880006.

Step 1:
If we divide 6 by 986, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 986

Let's proceed to step 2:
When dividing 63 by 986, we get 0 with a remainder of 63.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 63 after subtracting 0 from 63.
Take the next digit (8) from the dividend and append it to 63, then repeat: 638 / 986

On to step 3:
If we divide 638 by 986, we get 0 and a remainder of 638.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 638 after subtracting 0 from 638.
Include the next digit (8) from the dividend after 638, then repeat: 6388 / 986

Moving on to step 4:
The number 986 fits into 6388 6 times, leaving a remainder of 472.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
The remainder is 472 after subtracting 5916 from 6388.
Include the next digit (0) from the dividend after 472, then repeat: 4720 / 986

Advancing to step 5:
The number 986 fits into 4720 4 times, leaving a remainder of 776.
Put 4 as the next digit of the answer. 
Result so far: 64.0
Subtracting 3944 from 4720 leaves us with 776.
Fetch the next digit (0) from the dividend, attach it to 776 and continue: 7760 / 986

Moving on to step 6:
When dividing 7760 by 986, we get 7 with a remainder of 858.
The next digit of our result is 7. 
Result so far: 647.0
Subtract 6902 from 7760 to get 858.
Take the next digit (0) from the dividend and append it to 858, then repeat: 8580 / 986

Going ahead to step 7:
986 goes into 8580 8 times with a remainder of 692.
Record the quotient 8 as the next digit in the result. 
Result so far: 6478.0
Deduct 7888 from 8580 and we're left with 692.
Append the next digit (6) from the dividend to 692 and continue with: 6926 / 986

Step 8:
When dividing 6926 by 986, we get 7 with a remainder of 24.
The number 7 becomes the next digit in our result. 
Result so far: 64787.0
If we subtract 6902 from 6926, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 9:
986 can be fit into 240 0 times, resulting in a remainder of 240.
Use 0 as the next digit of our solution. 
Result so far: 64787.0
Subtract 0 from 240 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 10:
The number 986 fits into 2400 2 times, leaving a remainder of 428.
The number 2 becomes the next digit in our result. 
Result so far: 64787.02
The remainder is 428 after subtracting 1972 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Moving on to step 11:
If we divide 4280 by 986, we get 4 and a remainder of 336.
Use 4 as the next digit of our solution. 
Result so far: 64787.024
If we subtract 3944 from 4280, we get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Step 12:
When dividing 3360 by 986, we get 3 with a remainder of 402.
The next digit of our result is 3. 
Result so far: 64787.0243
Subtract 2958 from 3360 to get 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

Moving on to step 13:
The number 986 fits into 4020 4 times, leaving a remainder of 76.
Use 4 as the next digit of our solution. 
Result so far: 64787.02434
Subtract 3944 from 4020 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 14:
986 can be fit into 760 0 times, resulting in a remainder of 760.
Put 0 as the next digit of the answer. 
Result so far: 64787.02434
Subtracting 0 from 760 leaves us with 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Going ahead to step 15:
If we divide 7600 by 986, we get 7 and a remainder of 698.
Use 7 as the next digit of our solution. 
Result so far: 64787.0243407
The remainder is 698 after subtracting 6902 from 7600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6980, and continue the process.

Advancing to step 16:
986 can be fit into 6980 7 times, resulting in a remainder of 78.
The number 7 becomes the next digit in our result. 
Result so far: 64787.02434077
Subtract 6902 from 6980 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

The final outcome is 64787.02434077, with a leftover of 7.8e-08.
