We divide 76605601 by 210
We want to figure out the number of times 76605601 can be divided by 210.

Going ahead to step 1:
7 divided by 210 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 210

Moving on to step 2:
When dividing 76 by 210, we get 0 with a remainder of 76.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 76 after subtracting 0 from 76.
Include the next digit (6) from the dividend after 76, then repeat: 766 / 210

On to step 3:
766 divided by 210 is 3 with a remainder of 136.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 630 from 766, we get 136.
Fetch the next digit (0) from the dividend, attach it to 136 and continue: 1360 / 210

Moving on to step 4:
210 can be fit into 1360 6 times, resulting in a remainder of 100.
The next digit of our result is 6. 
Result so far: 36.0
The remainder is 100 after subtracting 1260 from 1360.
Include the next digit (5) from the dividend after 100, then repeat: 1005 / 210

Advancing to step 5:
If we divide 1005 by 210, we get 4 and a remainder of 165.
The number 4 becomes the next digit in our result. 
Result so far: 364.0
The remainder is 165 after subtracting 840 from 1005.
Include the next digit (6) from the dividend after 165, then repeat: 1656 / 210

Advancing to step 6:
1656 divided by 210 is 7 with a remainder of 186.
Write down 7 as next digit of the result. 
Result so far: 3647.0
The remainder is 186 after subtracting 1470 from 1656.
Grab the next digit (0) from the dividend, add it to 186, then carry on: 1860 / 210

Advancing to step 7:
210 can be fit into 1860 8 times, resulting in a remainder of 180.
Put 8 as the next digit of the answer. 
Result so far: 36478.0
If we take 1680 away from 1860, we end up with 180.
Include the next digit (1) from the dividend after 180, then repeat: 1801 / 210

On to step 8:
If we divide 1801 by 210, we get 8 and a remainder of 121.
The next digit of our result is 8. 
Result so far: 364788.0
If we take 1680 away from 1801, we end up with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Let's proceed to step 9:
210 can be fit into 1210 5 times, resulting in a remainder of 160.
Record the quotient 5 as the next digit in the result. 
Result so far: 364788.5
Deduct 1050 from 1210 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 10:
The number 210 fits into 1600 7 times, leaving a remainder of 130.
Put 7 as the next digit of the answer. 
Result so far: 364788.57
The remainder is 130 after subtracting 1470 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 11:
The number 210 fits into 1300 6 times, leaving a remainder of 40.
Use 6 as the next digit of our solution. 
Result so far: 364788.576
Deduct 1260 from 1300 and we're left 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.

Step 12:
When dividing 400 by 210, we get 1 with a remainder of 190.
Put 1 as the next digit of the answer. 
Result so far: 364788.5761
If we subtract 210 from 400, we get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Let's proceed to step 13:
210 goes into 1900 9 times with a remainder of 10.
The number 9 becomes the next digit in our result. 
Result so far: 364788.57619
If we subtract 1890 from 1900, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 14:
The number 210 fits into 100 0 times, leaving a remainder of 100.
The number 0 becomes the next digit in our result. 
Result so far: 364788.57619
Subtracting 0 from 100 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 15:
If we divide 1000 by 210, we get 4 and a remainder of 160.
Use 4 as the next digit of our solution. 
Result so far: 364788.5761904
If we subtract 840 from 1000, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 16:
If we divide 1600 by 210, we get 7 and a remainder of 130.
The next digit of our result is 7. 
Result so far: 364788.57619047
The remainder is 130 after subtracting 1470 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

The final result is 364788.57619047 with a remainder of 1.3e-07.
