We divide 15572039 by 770
We want to figure out the number of times 15572039 can be divided by 770.

Advancing to step 1:
770 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 770

On to step 2:
The number 770 fits into 15 0 times, leaving a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Take the next digit (5) from the dividend and append it to 15, then repeat: 155 / 770

On to step 3:
If we divide 155 by 770, we get 0 and a remainder of 155.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 155 and we're left with 155.
Take the next digit (7) from the dividend and append it to 155, then repeat: 1557 / 770

Step 4:
When dividing 1557 by 770, we get 2 with a remainder of 17.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 1540 from 1557, we get 17.
Grab the next digit (2) from the dividend, add it to 17, then carry on: 172 / 770

Moving on to step 5:
172 divided by 770 is 0 with a remainder of 172.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
Subtract 0 from 172 to get 172.
Fetch the next digit (0) from the dividend, attach it to 172 and continue: 1720 / 770

On to step 6:
If we divide 1720 by 770, we get 2 and a remainder of 180.
The number 2 becomes the next digit in our result. 
Result so far: 202.0
The remainder is 180 after subtracting 1540 from 1720.
Bring next digit (3) of the dividend behind the 180 and repeat the process: 1803 / 770

Step 7:
770 goes into 1803 2 times with a remainder of 263.
Put 2 as the next digit of the answer. 
Result so far: 2022.0
The remainder is 263 after subtracting 1540 from 1803.
Include the next digit (9) from the dividend after 263, then repeat: 2639 / 770

On to step 8:
When dividing 2639 by 770, we get 3 with a remainder of 329.
The number 3 becomes the next digit in our result. 
Result so far: 20223.0
Subtract 2310 from 2639 to get 329.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3290, and continue the process.

Moving on to step 9:
770 can be fit into 3290 4 times, resulting in a remainder of 210.
Write down 4 as next digit of the result. 
Result so far: 20223.4
If we take 3080 away from 3290, we end up with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Moving on to step 10:
The number 770 fits into 2100 2 times, leaving a remainder of 560.
Put 2 as the next digit of the answer. 
Result so far: 20223.42
If we take 1540 away from 2100, we end up with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Advancing to step 11:
770 goes into 5600 7 times with a remainder of 210.
Put 7 as the next digit of the answer. 
Result so far: 20223.427
Subtract 5390 from 5600 to get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Advancing to step 12:
If we divide 2100 by 770, we get 2 and a remainder of 560.
Use 2 as the next digit of our solution. 
Result so far: 20223.4272
Subtracting 1540 from 2100 leaves us with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Advancing to step 13:
When dividing 5600 by 770, we get 7 with a remainder of 210.
The number 7 becomes the next digit in our result. 
Result so far: 20223.42727
Deduct 5390 from 5600 and we're left with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Advancing to step 14:
770 goes into 2100 2 times with a remainder of 560.
The number 2 becomes the next digit in our result. 
Result so far: 20223.427272
Deduct 1540 from 2100 and we're left with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Going ahead to step 15:
If we divide 5600 by 770, we get 7 and a remainder of 210.
The number 7 becomes the next digit in our result. 
Result so far: 20223.4272727
The remainder is 210 after subtracting 5390 from 5600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

On to step 16:
If we divide 2100 by 770, we get 2 and a remainder of 560.
Use 2 as the next digit of our solution. 
Result so far: 20223.42727272
If we subtract 1540 from 2100, we get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

The final result is 20223.42727272 with a remainder of 5.6e-07.
