Let's divide 64123988 by 747
We're looking to find how many times 747 goes into 64123988.

On to step 1:
If we divide 6 by 747, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 747

Step 2:
747 goes into 64 0 times with a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 64 leaves us with 64.
Include the next digit (1) from the dividend after 64, then repeat: 641 / 747

Step 3:
The number 747 fits into 641 0 times, leaving a remainder of 641.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 641 leaves us with 641.
Grab the next digit (2) from the dividend, add it to 641, then carry on: 6412 / 747

Step 4:
747 goes into 6412 8 times with a remainder of 436.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 5976 from 6412, we get 436.
Fetch the next digit (3) from the dividend, attach it to 436 and continue: 4363 / 747

Moving on to step 5:
The number 747 fits into 4363 5 times, leaving a remainder of 628.
Write down 5 as next digit of the result. 
Result so far: 85.0
Subtracting 3735 from 4363 leaves us with 628.
Append the next digit (9) from the dividend to 628 and continue with: 6289 / 747

On to step 6:
When dividing 6289 by 747, we get 8 with a remainder of 313.
Record the quotient 8 as the next digit in the result. 
Result so far: 858.0
Deduct 5976 from 6289 and we're left with 313.
Grab the next digit (8) from the dividend, add it to 313, then carry on: 3138 / 747

Advancing to step 7:
747 goes into 3138 4 times with a remainder of 150.
The next digit of our result is 4. 
Result so far: 8584.0
Subtract 2988 from 3138 to get 150.
Include the next digit (8) from the dividend after 150, then repeat: 1508 / 747

Advancing to step 8:
747 can be fit into 1508 2 times, resulting in a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 85842.0
Subtracting 1494 from 1508 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 9:
140 divided by 747 is 0 with a remainder of 140.
Record the quotient 0 as the next digit in the result. 
Result so far: 85842.0
The remainder is 140 after subtracting 0 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 10:
If we divide 1400 by 747, we get 1 and a remainder of 653.
Record the quotient 1 as the next digit in the result. 
Result so far: 85842.01
Subtract 747 from 1400 to get 653.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6530, and continue the process.

On to step 11:
When dividing 6530 by 747, we get 8 with a remainder of 554.
Put 8 as the next digit of the answer. 
Result so far: 85842.018
Deduct 5976 from 6530 and we're left with 554.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5540, and continue the process.

Going ahead to step 12:
The number 747 fits into 5540 7 times, leaving a remainder of 311.
Write down 7 as next digit of the result. 
Result so far: 85842.0187
Deduct 5229 from 5540 and we're left with 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

Going ahead to step 13:
747 can be fit into 3110 4 times, resulting in a remainder of 122.
Put 4 as the next digit of the answer. 
Result so far: 85842.01874
Subtracting 2988 from 3110 leaves us with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Advancing to step 14:
747 goes into 1220 1 times with a remainder of 473.
Write down 1 as next digit of the result. 
Result so far: 85842.018741
If we subtract 747 from 1220, we get 473.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4730, and continue the process.

On to step 15:
747 goes into 4730 6 times with a remainder of 248.
Use 6 as the next digit of our solution. 
Result so far: 85842.0187416
Subtract 4482 from 4730 to get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Going ahead to step 16:
2480 divided by 747 is 3 with a remainder of 239.
The next digit of our result is 3. 
Result so far: 85842.01874163
If we take 2241 away from 2480, we end up with 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

The final result is 85842.01874163 with a remainder of 2.39e-07.
