73412390 ÷ 197 
We're looking to find how many times 197 goes into 73412390.

Moving on to step 1:
When dividing 7 by 197, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 197

On to step 2:
When dividing 73 by 197, we get 0 with a remainder of 73.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 73 to get 73.
Append the next digit (4) from the dividend to 73 and continue with: 734 / 197

Advancing to step 3:
197 goes into 734 3 times with a remainder of 143.
The next digit of our result is 3. 
Result so far: 3.0
If we take 591 away from 734, we end up with 143.
Grab the next digit (1) from the dividend, add it to 143, then carry on: 1431 / 197

Moving on to step 4:
When dividing 1431 by 197, we get 7 with a remainder of 52.
The next digit of our result is 7. 
Result so far: 37.0
If we subtract 1379 from 1431, we get 52.
Append the next digit (2) from the dividend to 52 and continue with: 522 / 197

Advancing to step 5:
197 goes into 522 2 times with a remainder of 128.
Record the quotient 2 as the next digit in the result. 
Result so far: 372.0
If we take 394 away from 522, we end up with 128.
Grab the next digit (3) from the dividend, add it to 128, then carry on: 1283 / 197

Moving on to step 6:
197 can be fit into 1283 6 times, resulting in a remainder of 101.
The next digit of our result is 6. 
Result so far: 3726.0
Deduct 1182 from 1283 and we're left with 101.
Append the next digit (9) from the dividend to 101 and continue with: 1019 / 197

Let's proceed to step 7:
When dividing 1019 by 197, we get 5 with a remainder of 34.
Record the quotient 5 as the next digit in the result. 
Result so far: 37265.0
The remainder is 34 after subtracting 985 from 1019.
Grab the next digit (0) from the dividend, add it to 34, then carry on: 340 / 197

On to step 8:
The number 197 fits into 340 1 times, leaving a remainder of 143.
The next digit of our result is 1. 
Result so far: 372651.0
Deduct 197 from 340 and we're left with 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Advancing to step 9:
1430 divided by 197 is 7 with a remainder of 51.
Record the quotient 7 as the next digit in the result. 
Result so far: 372651.7
Deduct 1379 from 1430 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 10:
510 divided by 197 is 2 with a remainder of 116.
Put 2 as the next digit of the answer. 
Result so far: 372651.72
Subtract 394 from 510 to get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Advancing to step 11:
197 can be fit into 1160 5 times, resulting in a remainder of 175.
Record the quotient 5 as the next digit in the result. 
Result so far: 372651.725
If we take 985 away from 1160, we end up with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Moving on to step 12:
197 can be fit into 1750 8 times, resulting in a remainder of 174.
Use 8 as the next digit of our solution. 
Result so far: 372651.7258
Deduct 1576 from 1750 and we're left with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Moving on to step 13:
197 goes into 1740 8 times with a remainder of 164.
Write down 8 as next digit of the result. 
Result so far: 372651.72588
Deduct 1576 from 1740 and we're left with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

The final result is 372651.72588 with a remainder of 0.000164.
