We're dividing 77139757 by 745 
Our goal is to divide 77139757 by 745.

Let's proceed to step 1:
If we divide 7 by 745, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 745

Moving on to step 2:
The number 745 fits into 77 0 times, leaving a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Include the next digit (1) from the dividend after 77, then repeat: 771 / 745

Let's proceed to step 3:
771 divided by 745 is 1 with a remainder of 26.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 745 from 771 to get 26.
Bring next digit (3) of the dividend behind the 26 and repeat the process: 263 / 745

Advancing to step 4:
745 goes into 263 0 times with a remainder of 263.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we subtract 0 from 263, we get 263.
Fetch the next digit (9) from the dividend, attach it to 263 and continue: 2639 / 745

On to step 5:
The number 745 fits into 2639 3 times, leaving a remainder of 404.
Record the quotient 3 as the next digit in the result. 
Result so far: 103.0
Deduct 2235 from 2639 and we're left with 404.
Fetch the next digit (7) from the dividend, attach it to 404 and continue: 4047 / 745

Moving on to step 6:
745 goes into 4047 5 times with a remainder of 322.
The next digit of our result is 5. 
Result so far: 1035.0
The remainder is 322 after subtracting 3725 from 4047.
Append the next digit (5) from the dividend to 322 and continue with: 3225 / 745

Step 7:
3225 divided by 745 is 4 with a remainder of 245.
Put 4 as the next digit of the answer. 
Result so far: 10354.0
Deduct 2980 from 3225 and we're left with 245.
Bring next digit (7) of the dividend behind the 245 and repeat the process: 2457 / 745

Step 8:
745 goes into 2457 3 times with a remainder of 222.
Put 3 as the next digit of the answer. 
Result so far: 103543.0
If we take 2235 away from 2457, we end up with 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Step 9:
When dividing 2220 by 745, we get 2 with a remainder of 730.
The next digit of our result is 2. 
Result so far: 103543.2
If we subtract 1490 from 2220, we get 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7300, and continue the process.

Moving on to step 10:
The number 745 fits into 7300 9 times, leaving a remainder of 595.
Record the quotient 9 as the next digit in the result. 
Result so far: 103543.29
Subtracting 6705 from 7300 leaves us with 595.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5950, and continue the process.

Step 11:
When dividing 5950 by 745, we get 7 with a remainder of 735.
The number 7 becomes the next digit in our result. 
Result so far: 103543.297
If we take 5215 away from 5950, we end up with 735.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7350, and continue the process.

Step 12:
If we divide 7350 by 745, we get 9 and a remainder of 645.
The next digit of our result is 9. 
Result so far: 103543.2979
If we subtract 6705 from 7350, we get 645.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6450, and continue the process.

Let's proceed to step 13:
If we divide 6450 by 745, we get 8 and a remainder of 490.
Put 8 as the next digit of the answer. 
Result so far: 103543.29798
If we take 5960 away from 6450, we end up with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Advancing to step 14:
745 goes into 4900 6 times with a remainder of 430.
The next digit of our result is 6. 
Result so far: 103543.297986
If we take 4470 away from 4900, we end up with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

On to step 15:
745 can be fit into 4300 5 times, resulting in a remainder of 575.
Record the quotient 5 as the next digit in the result. 
Result so far: 103543.2979865
Deduct 3725 from 4300 and we're left with 575.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5750, and continue the process.

On to step 16:
When dividing 5750 by 745, we get 7 with a remainder of 535.
Write down 7 as next digit of the result. 
Result so far: 103543.29798657
Deduct 5215 from 5750 and we're left with 535.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5350, and continue the process.

In conclusion, the division gives 103543.29798657 with a balance of 5.35e-07.
