64171345 ÷ 738 
Our goal is to divide 64171345 by 738.

Moving on to step 1:
6 divided by 738 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 738

On to step 2:
738 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
If we subtract 0 from 64, we get 64.
Take the next digit (1) from the dividend and append it to 64, then repeat: 641 / 738

Moving on to step 3:
If we divide 641 by 738, we get 0 and a remainder of 641.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 641, we get 641.
Append the next digit (7) from the dividend to 641 and continue with: 6417 / 738

Let's proceed to step 4:
The number 738 fits into 6417 8 times, leaving a remainder of 513.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 5904 from 6417 to get 513.
Take the next digit (1) from the dividend and append it to 513, then repeat: 5131 / 738

Moving on to step 5:
5131 divided by 738 is 6 with a remainder of 703.
Record the quotient 6 as the next digit in the result. 
Result so far: 86.0
If we take 4428 away from 5131, we end up with 703.
Fetch the next digit (3) from the dividend, attach it to 703 and continue: 7033 / 738

Advancing to step 6:
738 can be fit into 7033 9 times, resulting in a remainder of 391.
Record the quotient 9 as the next digit in the result. 
Result so far: 869.0
The remainder is 391 after subtracting 6642 from 7033.
Append the next digit (4) from the dividend to 391 and continue with: 3914 / 738

Step 7:
3914 divided by 738 is 5 with a remainder of 224.
Record the quotient 5 as the next digit in the result. 
Result so far: 8695.0
Subtracting 3690 from 3914 leaves us with 224.
Take the next digit (5) from the dividend and append it to 224, then repeat: 2245 / 738

Going ahead to step 8:
738 can be fit into 2245 3 times, resulting in a remainder of 31.
The number 3 becomes the next digit in our result. 
Result so far: 86953.0
Subtracting 2214 from 2245 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 9:
738 goes into 310 0 times with a remainder of 310.
Record the quotient 0 as the next digit in the result. 
Result so far: 86953.0
If we take 0 away from 310, we end up with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Advancing to step 10:
738 goes into 3100 4 times with a remainder of 148.
Record the quotient 4 as the next digit in the result. 
Result so far: 86953.04
Subtract 2952 from 3100 to get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Moving on to step 11:
738 goes into 1480 2 times with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 86953.042
If we subtract 1476 from 1480, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 12:
When dividing 40 by 738, we get 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 86953.042
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 13:
If we divide 400 by 738, we get 0 and a remainder of 400.
Write down 0 as next digit of the result. 
Result so far: 86953.042
Subtract 0 from 400 to get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Our division results in 86953.042 with a remaining 0.0004.
