63210549 ÷ 749 
Our goal is to divide 63210549 by 749.

Step 1:
749 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 749

Let's proceed to step 2:
If we divide 63 by 749, we get 0 and a remainder of 63.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 63, we end up with 63.
Append the next digit (2) from the dividend to 63 and continue with: 632 / 749

Advancing to step 3:
The number 749 fits into 632 0 times, leaving a remainder of 632.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 632, we get 632.
Fetch the next digit (1) from the dividend, attach it to 632 and continue: 6321 / 749

On to step 4:
6321 divided by 749 is 8 with a remainder of 329.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 5992 away from 6321, we end up with 329.
Take the next digit (0) from the dividend and append it to 329, then repeat: 3290 / 749

Advancing to step 5:
When dividing 3290 by 749, we get 4 with a remainder of 294.
Write down 4 as next digit of the result. 
Result so far: 84.0
Deduct 2996 from 3290 and we're left with 294.
Fetch the next digit (5) from the dividend, attach it to 294 and continue: 2945 / 749

Going ahead to step 6:
749 goes into 2945 3 times with a remainder of 698.
The number 3 becomes the next digit in our result. 
Result so far: 843.0
The remainder is 698 after subtracting 2247 from 2945.
Include the next digit (4) from the dividend after 698, then repeat: 6984 / 749

Step 7:
6984 divided by 749 is 9 with a remainder of 243.
The next digit of our result is 9. 
Result so far: 8439.0
If we take 6741 away from 6984, we end up with 243.
Include the next digit (9) from the dividend after 243, then repeat: 2439 / 749

On to step 8:
If we divide 2439 by 749, we get 3 and a remainder of 192.
Put 3 as the next digit of the answer. 
Result so far: 84393.0
Subtracting 2247 from 2439 leaves us with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Let's proceed to step 9:
When dividing 1920 by 749, we get 2 with a remainder of 422.
Write down 2 as next digit of the result. 
Result so far: 84393.2
If we take 1498 away from 1920, we end up with 422.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

Moving on to step 10:
4220 divided by 749 is 5 with a remainder of 475.
The next digit of our result is 5. 
Result so far: 84393.25
If we subtract 3745 from 4220, we get 475.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

Going ahead to step 11:
749 goes into 4750 6 times with a remainder of 256.
Use 6 as the next digit of our solution. 
Result so far: 84393.256
Subtracting 4494 from 4750 leaves us with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Moving on to step 12:
2560 divided by 749 is 3 with a remainder of 313.
Write down 3 as next digit of the result. 
Result so far: 84393.2563
Subtract 2247 from 2560 to get 313.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3130, and continue the process.

Advancing to step 13:
When dividing 3130 by 749, we get 4 with a remainder of 134.
Write down 4 as next digit of the result. 
Result so far: 84393.25634
Deduct 2996 from 3130 and we're left with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Step 14:
If we divide 1340 by 749, we get 1 and a remainder of 591.
Put 1 as the next digit of the answer. 
Result so far: 84393.256341
Deduct 749 from 1340 and we're left with 591.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5910, and continue the process.

On to step 15:
749 goes into 5910 7 times with a remainder of 667.
Put 7 as the next digit of the answer. 
Result so far: 84393.2563417
If we subtract 5243 from 5910, we get 667.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6670, and continue the process.

Going ahead to step 16:
When dividing 6670 by 749, we get 8 with a remainder of 678.
The next digit of our result is 8. 
Result so far: 84393.25634178
Deduct 5992 from 6670 and we're left with 678.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6780, and continue the process.

The final outcome is 84393.25634178, with a leftover of 6.78e-07.
