91213806 ÷ 140 
Let's see how many times 140 fits into 91213806.

Moving on to step 1:
140 can be fit into 9 0 times, resulting in a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 140

Let's proceed to step 2:
The number 140 fits into 91 0 times, leaving a remainder of 91.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 91, we get 91.
Grab the next digit (2) from the dividend, add it to 91, then carry on: 912 / 140

Going ahead to step 3:
If we divide 912 by 140, we get 6 and a remainder of 72.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we subtract 840 from 912, we get 72.
Fetch the next digit (1) from the dividend, attach it to 72 and continue: 721 / 140

Advancing to step 4:
The number 140 fits into 721 5 times, leaving a remainder of 21.
Record the quotient 5 as the next digit in the result. 
Result so far: 65.0
Subtract 700 from 721 to get 21.
Fetch the next digit (3) from the dividend, attach it to 21 and continue: 213 / 140

Going ahead to step 5:
The number 140 fits into 213 1 times, leaving a remainder of 73.
The number 1 becomes the next digit in our result. 
Result so far: 651.0
Deduct 140 from 213 and we're left with 73.
Bring next digit (8) of the dividend behind the 73 and repeat the process: 738 / 140

On to step 6:
140 goes into 738 5 times with a remainder of 38.
Put 5 as the next digit of the answer. 
Result so far: 6515.0
Deduct 700 from 738 and we're left with 38.
Bring next digit (0) of the dividend behind the 38 and repeat the process: 380 / 140

Moving on to step 7:
When dividing 380 by 140, we get 2 with a remainder of 100.
The number 2 becomes the next digit in our result. 
Result so far: 65152.0
The remainder is 100 after subtracting 280 from 380.
Bring next digit (6) of the dividend behind the 100 and repeat the process: 1006 / 140

Advancing to step 8:
The number 140 fits into 1006 7 times, leaving a remainder of 26.
Put 7 as the next digit of the answer. 
Result so far: 651527.0
If we subtract 980 from 1006, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 9:
When dividing 260 by 140, we get 1 with a remainder of 120.
Write down 1 as next digit of the result. 
Result so far: 651527.1
Subtracting 140 from 260 leaves us with 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 10:
If we divide 1200 by 140, we get 8 and a remainder of 80.
The number 8 becomes the next digit in our result. 
Result so far: 651527.18
The remainder is 80 after subtracting 1120 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 11:
The number 140 fits into 800 5 times, leaving a remainder of 100.
Record the quotient 5 as the next digit in the result. 
Result so far: 651527.185
The remainder is 100 after subtracting 700 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 12:
The number 140 fits into 1000 7 times, leaving a remainder of 20.
The next digit of our result is 7. 
Result so far: 651527.1857
If we subtract 980 from 1000, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 13:
When dividing 200 by 140, we get 1 with a remainder of 60.
Write down 1 as next digit of the result. 
Result so far: 651527.18571
Subtracting 140 from 200 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 14:
If we divide 600 by 140, we get 4 and a remainder of 40.
Put 4 as the next digit of the answer. 
Result so far: 651527.185714
The remainder is 40 after subtracting 560 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 15:
140 goes into 400 2 times with a remainder of 120.
The number 2 becomes the next digit in our result. 
Result so far: 651527.1857142
The remainder is 120 after subtracting 280 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 16:
1200 divided by 140 is 8 with a remainder of 80.
Use 8 as the next digit of our solution. 
Result so far: 651527.18571428
If we subtract 1120 from 1200, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

In conclusion, the division gives 651527.18571428 with a balance of 8e-08.
