We look at the division of 64473197 by 620 
We're looking to find how many times 620 goes into 64473197.

Let's proceed to step 1:
6 divided by 620 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 620

On to step 2:
64 divided by 620 is 0 with a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Append the next digit (4) from the dividend to 64 and continue with: 644 / 620

Going ahead to step 3:
620 goes into 644 1 times with a remainder of 24.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 620 from 644, we get 24.
Take the next digit (7) from the dividend and append it to 24, then repeat: 247 / 620

Step 4:
When dividing 247 by 620, we get 0 with a remainder of 247.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we subtract 0 from 247, we get 247.
Bring next digit (3) of the dividend behind the 247 and repeat the process: 2473 / 620

Step 5:
620 can be fit into 2473 3 times, resulting in a remainder of 613.
Put 3 as the next digit of the answer. 
Result so far: 103.0
The remainder is 613 after subtracting 1860 from 2473.
Grab the next digit (1) from the dividend, add it to 613, then carry on: 6131 / 620

Advancing to step 6:
6131 divided by 620 is 9 with a remainder of 551.
Write down 9 as next digit of the result. 
Result so far: 1039.0
If we subtract 5580 from 6131, we get 551.
Bring next digit (9) of the dividend behind the 551 and repeat the process: 5519 / 620

On to step 7:
When dividing 5519 by 620, we get 8 with a remainder of 559.
The number 8 becomes the next digit in our result. 
Result so far: 10398.0
If we subtract 4960 from 5519, we get 559.
Grab the next digit (7) from the dividend, add it to 559, then carry on: 5597 / 620

Let's proceed to step 8:
620 can be fit into 5597 9 times, resulting in a remainder of 17.
Use 9 as the next digit of our solution. 
Result so far: 103989.0
If we take 5580 away from 5597, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 9:
170 divided by 620 is 0 with a remainder of 170.
Use 0 as the next digit of our solution. 
Result so far: 103989.0
Subtracting 0 from 170 leaves us with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

On to step 10:
1700 divided by 620 is 2 with a remainder of 460.
The number 2 becomes the next digit in our result. 
Result so far: 103989.02
Deduct 1240 from 1700 and we're left with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

On to step 11:
620 goes into 4600 7 times with a remainder of 260.
The number 7 becomes the next digit in our result. 
Result so far: 103989.027
The remainder is 260 after subtracting 4340 from 4600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Advancing to step 12:
2600 divided by 620 is 4 with a remainder of 120.
Put 4 as the next digit of the answer. 
Result so far: 103989.0274
Subtract 2480 from 2600 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 13:
If we divide 1200 by 620, we get 1 and a remainder of 580.
The number 1 becomes the next digit in our result. 
Result so far: 103989.02741
If we subtract 620 from 1200, we get 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Going ahead to step 14:
620 goes into 5800 9 times with a remainder of 220.
Record the quotient 9 as the next digit in the result. 
Result so far: 103989.027419
If we subtract 5580 from 5800, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Going ahead to step 15:
If we divide 2200 by 620, we get 3 and a remainder of 340.
Put 3 as the next digit of the answer. 
Result so far: 103989.0274193
If we subtract 1860 from 2200, we get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

On to step 16:
When dividing 3400 by 620, we get 5 with a remainder of 300.
Record the quotient 5 as the next digit in the result. 
Result so far: 103989.02741935
Subtracting 3100 from 3400 leaves us with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

In conclusion, the division gives 103989.02741935 with a balance of 3e-07.
