39818101 divided by 770 
We want to figure out the number of times 39818101 can be divided by 770.

On to step 1:
3 divided by 770 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 770

Let's proceed to step 2:
If we divide 39 by 770, we get 0 and a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Bring next digit (8) of the dividend behind the 39 and repeat the process: 398 / 770

Moving on to step 3:
If we divide 398 by 770, we get 0 and a remainder of 398.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 398 to get 398.
Append the next digit (1) from the dividend to 398 and continue with: 3981 / 770

Advancing to step 4:
The number 770 fits into 3981 5 times, leaving a remainder of 131.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtracting 3850 from 3981 leaves us with 131.
Take the next digit (8) from the dividend and append it to 131, then repeat: 1318 / 770

Moving on to step 5:
770 goes into 1318 1 times with a remainder of 548.
The number 1 becomes the next digit in our result. 
Result so far: 51.0
If we subtract 770 from 1318, we get 548.
Append the next digit (1) from the dividend to 548 and continue with: 5481 / 770

Going ahead to step 6:
When dividing 5481 by 770, we get 7 with a remainder of 91.
The next digit of our result is 7. 
Result so far: 517.0
Subtracting 5390 from 5481 leaves us with 91.
Bring next digit (0) of the dividend behind the 91 and repeat the process: 910 / 770

Going ahead to step 7:
If we divide 910 by 770, we get 1 and a remainder of 140.
Write down 1 as next digit of the result. 
Result so far: 5171.0
Subtract 770 from 910 to get 140.
Bring next digit (1) of the dividend behind the 140 and repeat the process: 1401 / 770

On to step 8:
The number 770 fits into 1401 1 times, leaving a remainder of 631.
Use 1 as the next digit of our solution. 
Result so far: 51711.0
Subtract 770 from 1401 to get 631.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6310, and continue the process.

Step 9:
If we divide 6310 by 770, we get 8 and a remainder of 150.
The number 8 becomes the next digit in our result. 
Result so far: 51711.8
If we subtract 6160 from 6310, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Going ahead to step 10:
If we divide 1500 by 770, we get 1 and a remainder of 730.
Put 1 as the next digit of the answer. 
Result so far: 51711.81
If we subtract 770 from 1500, 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 11:
770 can be fit into 7300 9 times, resulting in a remainder of 370.
The number 9 becomes the next digit in our result. 
Result so far: 51711.819
Deduct 6930 from 7300 and we're left with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Moving on to step 12:
770 goes into 3700 4 times with a remainder of 620.
Put 4 as the next digit of the answer. 
Result so far: 51711.8194
If we subtract 3080 from 3700, we get 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Advancing to step 13:
6200 divided by 770 is 8 with a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 51711.81948
Subtracting 6160 from 6200 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 14:
When dividing 400 by 770, we get 0 with a remainder of 400.
Write down 0 as next digit of the result. 
Result so far: 51711.81948
Deduct 0 from 400 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Step 15:
770 can be fit into 4000 5 times, resulting in a remainder of 150.
Put 5 as the next digit of the answer. 
Result so far: 51711.8194805
If we take 3850 away from 4000, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 16:
If we divide 1500 by 770, we get 1 and a remainder of 730.
Use 1 as the next digit of our solution. 
Result so far: 51711.81948051
If we take 770 away from 1500, we end up with 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7300, and continue the process.

The final result is 51711.81948051 with a remainder of 7.3e-07.
